The essay that follows is a radio address by Leslie Alva Kenoyer, who served from 1922 to 1953 as Professor and Chairman of the Biology Department at Western Michigan University –at that time Western State Teachers College .  The piece is dated April 16, 1935.  It was written for Western’s Radio Hour, which was evidently a continuing feature on station WKZO.

NEWTON WOODS 

Leslie Kenoyer 

“Woodman, spare that tree, Touch not a single bough.”

 The sentiment that inspired this poem has not been firmly enough established in the minds of southern Michigan people to save from destruction any more than the most scattered remnants of our once beautiful and glorious forest lands. Some fifty thousand years ago the great continental glacier receded from what is now Michigan leaving a raw and barren glacial clay, streaked here and there with sand and gravel. Such soil, in the cool climate then found here, could support only a meager arctic vegetation, consisting of such low, spreading plants as we find today in our cold bogs. The rain and sun gradually brought about favorable chemical changes in the soil and the plants gradually decayed to form humus, hence, in the course of a few centuries, the scant arctic vegetation was replaced by larger shrubs. Centuries later trees occupied the ground, starting with the poplars and developing from stage to stage to dense shady forests of beech and sugar maple. such as covered much of southern Michigan 110 years ago when the government divided our land into townships and sections.

It was inevitable that the trees should succumb to the lumberman’s axe, when the land was cleared for farm homesteads, but it is particularly unfortunate that their removal should have been so complete. Indeed we have here and there a small woodlot to serve as a rather meager sample of the forests that were. but larger tracts are now exceedingly scarce. One of the finest and most extensive remaining areas is Newton Woods in Cass County, adjoining the road from Decatur to Cassopolis, and not far from the village of Volinia. Here are several hundred acres of practically virgin timber, including large blocks of both the beech-maple and oak-hickory types of timber. The trees of this forest were large long before southern Michigan was surveyed and opened to the settler. Among them is an elm which now lifts its head to the majestic height of 150 feet and has a circumference. three feet above ground of 24 feet [91-92 inches in diameter]. Some believe it to be the largest tree now standing in Michigan. There is also a magnificent group of giant tulip or whitewood, the largest of which is 145 feet high, 90 feet to the first branch and 30 feet in circumference [114-115 inches in diameter]. It takes three to five centuries to grow such trees as these.

Ten years ago we could see from our college campus, at a distance of eight or nine miles, a stately elm, towering far above the other trees. Suddenly this tree ceased to be seen, and we learned that it had been sold for $100 for the manufacture of barrel staves. On visiting the stump and counting the rings of growth, I found that the tree was considerably over 400 years old. It was a sapling when Columbus crossed the Atlantic in his puny sailing vessels. Probably the barrels have worn out and the $100 has been long since spent and forgotten, but it will take 400 years to grow another such tree.

When a forest is cut, it is not only the trees that go. The shrubs and the herbs, the orchids and other rare plants, the mosses and lichens that form the turf, will not live when deprived of the shade of the trees. The disappearance of this ground cover permits the erosion of the soil, which represents the accumulation of many thousands of years. The insects, the birds, and the beasts are dislodged from their accustomed haunts, many of them to perish. Hence the restoration of a denuded area cannot be accomplished by the mere planting of trees, nor does a planted forest ever prove a satisfactory substitute for a destroyed native forest.  The old conditions will not and cannot be restored, once the forest is gone.  How, then, will the next generation know anything of the beauties and glories of the forest with its wonderful variety of plant and animal forms  This is a question which our generation must answer.

A part of the Newton Woods is now in the hands of a lumber company and some cutting has already been done, but there is a chance that it may yet be rescued if the public will take sufficient interest in its preservation. The lumber firm is kindly witholding operations in view of an aggressive campaign that is now being sponsored by the Michigan Academy [of Science, Arts, and Letters], the Michigan Forestry Association, and other organizations and individuals who feel that the value to the people of such reserves for the continuation of our wild life is one that cannot be measured in mere dollars. The present leader of this movement is Shirley W. Allen, University of Michigan, Ann Arbor.

Professor Allen would like to hear from all who are interested in finding some means to save the tract.  It is well to bear in mind that our present state parks are mostly in northern Michigan remote from centers of population. Here is a real wilderness with immense trees, a small stream, a profusion of wild flowers, birds, and other natural beauties easy of access to a million people.  We cannot blame property owners for wishing to realize from their investments, but we deplore the fact that the people are not awake to the desirability of keeping the few remaining bits of out landscape as nature gave them to us, free from the artificial modifications imposed  by farm and city development.  With an awakened public, our officials and our public-spirited citizens of means would put forth the necessary efforts to save from the general destruction these remnants of wild nature for the instruction and enjoyment of generations yet to come.

Kenoyer’s comments on post-glacial vegetation change hold up well enough as a broad pattern.  However, the quoted estimate of 50,000 years ago since the last ice sheet melted from southern Michigan is too high. Something on the order of 15,000 years would be closer to the interval based on current evidence.

I like Kenoyer’s plea for protecting natural areas “for the enjoyment and instruction” of later generations.  If I were to revise it I might write “enjoyment, instruction, and health of our own and later generations.” But Kenoyer’s plea for land conservation was accurate and eloquent exactly as he wrote it and, in 1935 on a radio broadcast, far ahead of its time.

The script of this and a few other of Kenoyer’s radio addresses, preserved by Biology Prof. Frank Hinds, have been deposited in the WMU Archives and Regional History Collection

Kenoyer received his Ph.D. in 1916, evidently done in some sort of joint arrangement between the University of Chicago and Iowa State University.  He is credited with receiving the first Ph.D. granted by  what was then The Iowa State College of Agriculture and Mechanic Arts.  Kenoyer’s thesis research dealt with environmental influences on nectar secretion.  This and his research interests as shown in later life seem clearly in line with the work being done at Chicago by Henry Chandler Cowles and the other faculty and graduate students.

Kenoyer was born in 1883 in Dover, a small community in north-central Illinois. After completing his Ph.D., he taught botany in India for six years, then spent a year at Michigan State before coming to Kalamazoo.  He became head of the Biology Department soon after arriving, when LeRoy H. Harvey died.

Newton Woods was saved by a donation of  land (580 acres) and an endowment by Fred Russ in 1939 .  The story is complicated (and deserves a thorough treatment by someone), but there is a rough correspondence between the “Newton Woods” of the 1930s and Fred Russ Forest managed by Michigan State University.  MSU applies the name “Newton Woods” to 40 acres of old-growth hardwood, the only part of the forest that is protected from timber cutting.  E. Lucy Braun in her monumental study Deciduous Forests of Eastern North America (1950. Blakiston, Philadelphia) sampled two distinct areas at Russ Forest, probably in the early 1940s (pp 318-320).  One was beech-sugar maple with American elm, black walnut, tulip tree, and several other species well represented. The other was dominated by white oak with sugar maple second and red oak and black walnut tied for third.  Evidently, the oak-maple stand is what MSU terms “Newton Woods.”  

Whether Kenoyer and some of the other individuals and groups who worked to preserve Newton Woods 75 years ago would  be wholly be satisfied with the outcome is not certain.

Automobiles are a less serious contributor to ozone production since catalytic converters have been required. Photo in downtown Milwaukee, WI by Richard Brewer

President Obama made two serious mistakes early this fall. First, he told the Environmental Protection Agency to withdraw new, stronger, standards for ozone levels in the lower atmosphere that were intended to replace the standards held over from the Bush administration. Ozone (O₃) is an atmospheric pollutant dangerous to human health because it’s highly reactive in lung tissues. It’s involved in various respiratory diseases but evidently also in other sorts of human pathology; for example, it’s believed to contribute to the development of atherosclerosis. But ozone in the lower atmosphere also has many bad effects besides just our own health and life span.  It damages plants, lowering photosynthesis and growth and is implicated in die-offs of forest trees.

Ozone is produced in the lower atmosphere by reactions between nitrogen oxides and volatile organic compounds in the presence of sunlight. The nitrogen oxides and volatile organic compounds come mostly from power plants, various sorts of factories, automobiles, gasoline vapor, and chemical solvents.

There are interactions between ozone production and temperature and ozone effects and temperature, such that we get more ozone produced and stronger effects when temperatures are high. These are one of many kinds of interactions that may make global warming an even greater calamity than most of the early predictions claimed.

President Obama’s second mistake was his reason for turning down the new, science-based ozone recommendations. He said he wanted to reduce regulatory burdens and regulatory uncertainty. But tough regulations strictly enforced are what can make capitalism work. The last few years have shown us repeatedly how things go astray when politicians manage to weaken and thwart regulations.  Weakened regulations together with the unwillingness of federal agencies to enforce existing regulations were the main causes of the financial fiasco of 2007-2009 and the recession that came with it.

Michigan has been on the deregulation bandwagon right along.  In the DooDah parade of deregulation, it may even have been ahead of the bandwagon.  We had a governor a few years ago whose slogan was “Less enforcement, more compliance.”  Such a proposition if it were sincere would be fatuous, but considering everything, just calling it preposterous or ludicrous will probably have to serve.

President Obama seems to have accepted the argument of the extreme political right that there is a conflict between “the environment” and “the economy.”  For most Americans, the right wing lost on that issue 30 or 40 years ago. Some corporations tell us if the nation doesn’t give them lax environmental rules they’ll take their jobs overseas.  Since such corporations show little national loyalty, some have.

But the balance sheet we need to look at is the overall gain to our nation in terms of clean air and water, healthy citizens, healthy communities, and healthy ecosystems  compared with the cost of meeting any given environmental standard. Time after time we’ve seen that the costs of meeting new standards turns out lower than the company’s forecast, that new jobs are created connected with the improved technology needed, and that the overall national cost/benefit ratio is heavily in favor of the tougher standards.

Anyone who’s been paying attention anytime these past 40 years knows that.  Why doesn’t the President?

President Obama has another environmental decision coming up soon.  This is to accept or reject the proposed Keystone XL pipeline that would carry a form of crude oil processed from Canadian tar sands from Alberta to the U.S. Gulf Coast.  I hope to write more about this a little later.

The orchid is three birds orchid (Triphora trianthophora).  It’s known from Kalamazoo County and in fact from much of the eastern U.S., but in most places it has become rare. It is now considered threatened, endangered, or extirpated in most states. The last record in Michigan was evidently in 1981, from Berrien County.

It’s possible that three birds is gone from Kalamazoo County and Michigan. Perhaps the observations in the 20th century just caught the tail of a population dwindling toward extinction–in this region; three birds seems a little more numerous in the South.  However, there are some reasons why not many people are out looking in the beech-maple forests when it’s visible, and also some reasons why, even if you’re there, three birds isn’t necessarily easy to spot.

First, almost nothing else is in flower in the mesophytic forests at this time of year, so there’s not much to look at.  The many species of spring ephemerals that covered the ground in April and May are gone.  A few species that flower in summer are now in fruit, and it’s pleasant to be able to see the doll’s-eyes and blue cohosh.  But, in general, the beech-maple forests of late summer are dark, and the ground is obscured in many places with seedlings and saplings,

mostly sugar maple, or with thick foliage of ferns, wood nettle (Laportea), wild ginger, and a few other herbs.

Three birds is a short plant, 6 inches or thereabouts, so I imagine in the shade and under the foliage, it’s not easy to see. Nevertheless, considering how important rediscovering the species would be, if you can get to a beech-maple forest in the next few days, you ought to give it a try.

There is much yet to learn about the habitat and life history of three birds.  Within its mesophytic forest home, it’s said to favor sites where there’s a build-up of leaf litter and humus.  Probably this means small depressions.  Leaves accumulate other places, such as between two large fallen trunks, but I’m not sure if that microhabitat would be long-lived enough to allow time for the orchid to invade.  But maybe it would. From observations of the Michigan botanist Fred Case in his Orchids of the Western Great Lakes Region (Cranbrook Institute of Science, 1987), I suspect that most dispersal is through underground tuberoids that are dug up, carried off, and stored in the duff and litter by red squirrels, or perhaps chipmunks.

Late in the summer, fleshy stems sprout rapidly from the underground tuberoids.  Each plant bears only a few leaves which are oval, alternate, and clasp the stem.  Usually there will be a few stems in a clump. Not long after the plants appear, one or occasionally more of the buds open.  Flowering is possibly triggered by a couple of chilly nights in a row.  It is reported that most of the plants in a given area produce their first blooms at the same time.  After a day or so, the first set of blossoms shrivel, and in a few days, a second round of flowering may occur, and perhaps a third.

The flowers (often three per plant) are recognizably orchids but small, perhaps about an inch wide and an inch tall and are mostly whitish or pinkish with a greenish bearded stripe on the lip.  The fruits last for a couple of weeks before slits develop that allow the release of the spore-like seedsin the following days.  Although the plants are not at their showiest when they’re in fruit, this is the probably the longest period of their above-ground life.  You can see how the plant looks with fruit at this Connecticut Botanical Society site with photos by Eleanor Saulys.   The same site shows some plants in flower. Many more photos of flowering plants by Jim Fowler are shown at the North Carolina site  linked to earlier.

So, have a look at the photos and head for the nearest beech-maple forest.  If you find three birds orchids, please tell us about it in the comments section.  But don’t mention exactly where you found them. (If you do give information that might allow someone to locate them, I’ll edit your comment to remove those details.)  Rare plants, especially such things as orchids, have been known to disappear from sites that become known.  However, you should let the Michigan Natural Features Inventory know.  They’ll be tickled that three birds is not extinct in Michigan.–as will we all.

At a time in southwest Michigan when protecting all our remaining natural lands and waters would make sense for human health and economic viability, threats continue.

This morning I received the message copied in boldface below from the Saugatuck Dunes Coastal Alliance.  It is their updated look at the controversy involving the Lake Michigan sand dunes and beaches north of the mouth of the Kalamazoo River at Saugatuck, Allegan County, Michigan.  Background information is available at the Alliance’s website .  A December 2010 Wall Street Journal article, A Billionaire’s Dune Duel, is also informative. Some history, including the hope to have protected public lands from the Oval Beach north through Saugatuck State Park, is given at the website of the Concerned Citizens for Saugatuck State Park.

We want to take a moment to alert you to what is currently happening to defend local zoning in the Saugatuck area.

• On July 22nd the Saugatuck Township Board appeared to ignore four hours of testimony by many well-informed township residents asking them to consider all other possible solutions to the proposed settlement between Aubrey McClendon and Saugatuck Township to the on-going federal lawsuit. The Township Board unanimously passed the settlement.
• On July 29th three local groups – Saugatuck Dunes Coastal Alliance, Laketown Alliance for Neighborly Development and the Kalamazoo River Protection Association – file  a request for Judge Maloney to hold a fairness hearing. A fairness hearing, which is common in many different types of cases that affect communities or large numbers of third-parties, is used to ensure consent decrees are fair, reasonable and legal, and in the public interest.  Our belief is that the proposed consent decree does not meet these standards and should, therefore, be rejected by the court.
• On July 29th the National Trust for Historic Preservation also file a request for a fairness hearing. The National Trust is represented by Kalamazoo-based law firm Miller Canfield.
• On August 1st several Township residents who live close to the McClendon property also file papers requesting a fairness hearing. The neighbors are represented by Grand Rapids-based law firm Varnum.
• On Monday, August 8th additional neighbors, one of whom is completely surrounded by McClendon’s land, sign onto the request for a fairness hearing filed by Varnum.

We have taken this step (filing for a fairness hearing on July 29th) as we believe that this proposed consent decree is illegal because it circumvents local zoning laws, violates the State-mandated rezoning process, and blocks the Saugatuck Township Board’s oversight of the development.

To put it simply, the fundamental problem with the proposed settlement is that it includes provisions that neither Mr. McClendon nor the Township Board has the legal authority to do on their own. That is, they have overridden local zoning regulations without a proper process and they have approved a commercial development that is not permitted under current zoning and would also have not been permitted under the property’s previous zoning.

Under Michigan law, zoning ordinances should be based on the applicable master plan. The proposed consent decree, however, permits commercial-type uses that are clearly prohibited by the Township’s zoning ordinance and the Tri-Community Comprehensive Master Plan. It does this without any proper process or prior consultation with the Cities of Saugatuck and  Douglas, the two other jurisdictions that participated in the development of this Master Plan. Additionally, under this settlement, the Township has contracted away its legislative powers now and in the future in violation of Michigan law.

Furthermore, the Township Board reached the decision to accept the settlement under duress. This proposed settlement is not a “compromise” as touted by the McClendon team. It is, in fact, a “take it or leave it” offer, made after the Township was forced to incur hundreds of thousands of dollars of legal expenses, and then threatened with never ending legal expenses in the future. Only then did the Township capitulate to Mr. McClendon’s demands.

We appreciate the pressure the Township Board has been under and the difficult decision they were faced with. But this settlement sets a dangerous precedent because it suggests that there is one set of rules for investors with deep pockets who are willing to threaten the Township with bankruptcy and another set of rules for everyone else.

With the various requests for a fairness hearing, the community is stating publicly and before the Court that this proposed consent decree is unfair and illegal and should be set aside by the court.

We understand that many in the community are concerned about the costs of further litigation and the unfortunate divisions that this development proposal has caused in our community. As a practical matter, we agree that a fair settlement should be negotiated. That is why we are also calling on the township to propose to Mr. McClendon a mediation process, such as proposed by former Senator Birkholz, in order to reach a fair and legal settlement. We understand that Mr. McClendon owns the property and has a right to develop it. We only ask that it be developed in a manner that is consistent local zoning laws.

Many of you are asking how you can help. Thank you!  One important thing everyone can easily do is send this update out widely, post on facebook, and remind people that this issue is far from over.

Also, please keep repeating these three points:

1. The Coastal Allliance supports all property owners’ rights to develop their land legally and appropriately.

2. The Coastal Alliance supports locally determined zoning.

3. Aubrey McClendon sued Saugatuck Township to rewrite zoning laws. It’s worth noting that the Master Plan, from which these zoning laws originated, was unanimously approved by Saugatuck Township, Saugatuck City, and Douglas.

Wetland wilderness, however has not fallen quite so far…. Although many surviving wetlands have indeed suffered irreversible changes… it is remarkable how many of them remain relatively pristine. Most American wetlands have existed as such since the retreat of Pleistocene glaciers.  Some of their plant populations may, in many cases, be directly descended from the original wetland species of their locales.  The pleasure and adventure of experiencing a bog or marsh of native vegetation may bring us as close to experiencing true American wilderness as most of us may ever come.

–John Eastman

John Andrew Eastman was an American naturalist and writer and a Kalamazoo resident.  Of many publications, probably his most influential were three books, The Book of Forest and Thicket, The Book of Swamp and Bog, and  The Book of Field and Roadside.  They are field guides of a special, ecological sort.  Arranged by species of plant, they deal with the interactions of each species with its associates–consumers, parasites, competitors, mutualists–and with the physical features of its habitat.

The quotation is from the Introduction to the Swamp and Bog book and makes a point about many existing wetlands of North America that no one else has stated as directly:  Unlike most upland sites, wetland sites, if not destroyed, often preserve conditions and ecosystems with direct genetic connections to the landscapes encountered by the earliest European settlers–and, of course, by American Indians before them.

Many wetlands have another conservation connection: Pollen and other remains of plants and animals preserved in their sediments are the main evidence for reconstructing the vegetational and climatic history of the region surrounding the wetland basin.  Not mentioned in the Introduction, this important role is alluded to in the book’s entry on Mosses, Sphagnum (p.130).

Hazelnut catkins in Oshtemo Township, Michigan. Photo 10 April 2011 by Richard Brewer

Early this April, I saw a tall skinny shrub without leaves but with catkins.  It reminded me that early last fall I had come across a clump of similar skinny trunks that bore pointed, toothed leaves.  The leaves were more or less like leaves of several groups of woody plants–birches, elms, hornbeams, and conceivably a few others.  I had been puzzled by the plant and hadn’t identified it for sure but had narrowed it down to a handful of possibilities.  One of the possibilities had been American hazelnut (Corylus americanus).  The books I was using commented that catkins are produced in the fall but don’t open to produce pollen until the following spring.  These catkins weren’t quite open yet, but seeing them there tilted me toward thinking that the plants must be hazelnuts.

The plant was in a handy place to observe, so I was able to keep track of it over the next couple of weeks as the catkins lengthened and then opened, shedding pollen.

The pistillate flowers of hazelnut are tiny buds, but recognizable by the thin red styles–ready for pollen–poking out the end. The styles are easily seen with a lens. The hazelnuts when they ripen in the fall look like the European filbert of commerce, but smaller. They’re also similar in taste.

The first time I saw hazelnuts I was probably six or seven years old.  My parents took me along when they went hazelnut picking one day in the fall.  The spot wasn’t far from where we lived east of Murphysboro, Illinois, probably a quarter of a mile down the county road toward Route 13.  I enjoyed eating the nuts at the time but never became a big filbert fan.

I’ve seen hazelnut fruits in the wild in Michigan a few times, but never in these woods.  Two possibilities occur to me.  The first is that the woods are too shady, especially with the increasing abundance of red maple, for the shrubs to accumulate enough energy to produce fruits.  The second is that the nuts are so attractive to the squirrels, woodpeckers, and jays that they have always been eaten (or stored)  before I chance to wander by in the fall.

Now that I’m attuned to the look of hazel even without catkins or hazelnuts, I’ve seen several clumps  in both drier and wetter parts of the oak woods. Most of the clumps are between knee high and waist high, only a few head high or taller.

Since I’ve been in Michigan, I’ve associated hazelnut with the edges of prairies, and I think that’s apt.  But now I’ve begun to understand (1) its remarkably wide ecological amplitude and (2) how widespread it must have been in almost every permutation of prairie and savanna that existed in pre-settlement southwest Michigan.

One indication of hazelnut’s wide habitat occurrence can be drawn from John T. Curtis’s The Vegetation of Wisconsin. This excellent book has a species list in the back (after the Literature Cited and before the index), that gives the plant community where the species most frequently occurs and also given  the number of plant communities in which Curtis found the species in his studies. The community in which the species was found most often–the modal community–is presumably the most characteristic community; the number of communities from which the species is recorded is a measure of ecological amplitude of the species.

The book recognizes 34 plant communities. American hazelnut was reported most frequently from dry forest, but it occurred in 20 other communities, or  62 per cent in all.

I didn’t go through the species list line by line, but I did check on some species that I think of as occurring in a wide variety of situations. There were a few species in the 15-18 community range and at least one species that occurred in the same number of communities as hazelnut–21.  This was Cornus racemosa, gray dogwood.  Vitis riparia, river-bank grape, had a 22. There were only two species clearly ahead of  the hazelnut, dogwood, and grape.  These were Va. creeper, Parthenocissus quinquefolia, 1n 25 communities and poison ivy, Rhus radicans, in 26 (76%).  It may not be accidental that all five of these species are woody and have animal-dispersed seeds.

Hazelnut’s broad distribution more or less centered on dry forest fits well with the conception of oak openings that Kim Chapman and I expressed in an article (“Prairie and Savanna in Southern Lower Michigan: History, Classification, Ecology”) in the January 2008 Michigan Botanist.  We see oak openings in the pre-settlement landscape as a diverse community, the composition of which varied in space–different in low and high spots, north slopes and southwest slopes, sandy sites and gravelly sites. But it also varied in time at any given point based on the  latest disturbance (fire, tornado, insect infestation) and how recent it was, but also on the historic frequency of disturbance.  A north-facing slope running down to a pond in a small kettle might have included a set of plants much like mesic forest.  A gentle loamy slope after a few years of near-annual fires might have been covered with dry-mesic prairie.

This is oak openings in the sense of Michigan pioneer botanist Ruth Hoppin’s description (quoted on pages 7-8 of Chapman and Brewer). In this view, most of the prairie and savanna types are just different faces of one big community type.  Mesic prairie and bur oak plain, I would say, are different and so, of course, is mesic forest.

Hazelnut seems to have the life history traits to be a near-perfect fit to the oak openings habitat as it was.  Hazelnut can get around readily by the nuts being carried, and often buried, by mammals and birds. Over short distances, it spreads readily by rhizomes. It tolerates a wide range of light intensities though it tends to decline in deep shade.  It tolerates fire, but only up to a point. Most of its rhizomes and roots are in the upper six inches of soil.  Light fires kill the above-ground parts of the plant but stimulate vigorous sprouting from the rhizomes.  Fires hot enough to consume the litter often kill the underground parts.  Hence, hazelnut might be at least temporarily eliminated by fire from certain habitats where hot, litter-consuming fires occurred.

I suspect most of the hazelnut plants I’ve been finding in the Oshtemo oak woods are just hanging on, waiting for the fires the openings used to have, the fires that would stimulate sprouting and open the canopy to enough sunlight to yield a good crop of nuts. One more reason why few of the hazel bushes grow tall may be the high populations of deer these days.  Hazel is a favored browse plant of deer, so high populations may keep it pretty well clipped.

I need to give the results of the small trial mentioned a month ago, when I put out eight garlic mustard plants (four small and four large) that we had pulled up early in the spring on 23 April at the Audubon Society’s Harris Sanctuary.

I spread them out on the floor of an oak woods on a patch from which I had removed the leaf litter.

The upper parts of the larger plants remained plump and green for several days and flowers that had not been evident when the plants were pulled appeared on the large plants. (No flowers were seen on the small plants.)  Also, the tops turned upward and the roots turned down.  But soon the plants began to shrivel and darken.  The photo to the left is a view of one of the larger plants on 29 April. By 29 May, the plant bodies, including any flowers, had decomposed, with little structure still evident (see photo below).

On the basis of this small trial, it seems unnecessary to remove plants pulled early in the spring.

By early June, most of the second-year plants growing in the woods and on the roadsides have green fruits. It seems possible that large specimens pulled or clipped and tossed on the ground from late spring on might be able to draw enough water and energy from the fleshy leaves and stems to produce viable seeds.

Certainly, many of the invasive species websites tell us that only bagging and hauling the plants away from the control site can head off seed production and dispersal. The evidence is scant, but one study  (K. Solis, 1998, Restoration and Management Notes 16:223-224) seems to show that even plants pulled in the flower bud stage can produce viable seeds.  A serious, well-designed study of adequate sample size would be welcome.

Each town should have a park, or rather a primitive forest, of five hundred or a thousand acres, where a stick should never be cut for fuel, a common possession forever, for instruction and recreation. We hear of cow-commons and ministerial lots, but we want men-commons and lay lots, inalienable forever….

Button found 14 April 2011 and reused

All Walden Wood might have been preserved for our park forever, with Walden in its midst, and the Easterbrooks Country, an unoccupied area of some four square miles, might have been our huckleberry-field…. As some give to Harvard College or another institution, why might not another give a forest or huckleberry-field to Concord?

–Henry David Thoreau

Thoreau is well known as America’s philosopher-naturalist. Here he gives an early statement of the need to set aside natural land. By the mid-1800s, many people were lamenting the loss of the country’s wild lands, but few took the next step of recommending preservation.  In this passage and also other writings of his later years, Thoreau did.  He not only states that every town (what in the Midwest we call a township) ought to set aside a 500- to 1000-acre preserve, but also notes that the protection should be in perpetuity (“inalienable forever’) and suggests a method–by charitable donation to the town government.

This passage was in his journal for October 15, 1859, but he was also including it, slightly reworked, in his last book, eventually published in 2000 as Wild Fruit.

I spent the early part of the morning in the beech-maple forest.  It’s still early spring  and none of the spring wild flowers are blooming yet. A few things are up, notably wild leek.  It’s abundant in this sanctuary. The flowers don’t appear till June, long after the leaves are gone.  A few of last year’s flowering stalks are still upright–dry and pale tan–and a few of these still retain a black, shiny round seed.   Never more than one on any I noticed.

I saw quite a few patches of bedstraw, Galium aparine.  This early, they are short thin stems with whorls of miniature leaves.

A fair number of toothwort (Dentaria laciniata) plants were up and had buds.  Maybe they’ll be the first plants to flower here.  In a beech-maple forest in Pavilion Township I visited last weekend, harbinger of spring was in full bloom, but the species doesn’t occur at Harris.

In 40 minutes or so of walking, I found only one small patch of garlic mustard.  This includes my visiting 20 or so flagged sites where we had found and pulled garlic mustard in past years.  The new patch was not near any of the old ones.  But someone else might have spotted other plants.  The garlic mustard is short, just basal leaves; some other plants might have popped out for someone with good color vision.

I then picked up trash along the two roads that adjoin the sanctuary and walked back to the car through the field half of the sanctuary.  One plant species was in bloom in the field–a low member of the mustard family with small, very small, white flowers.  With its four white petals, it was pretty obviously a mustard, but I couldn’t satisfy myself just what the species was.  Probably in a week or so, when some of the flowers give rise to fruits, it’ll be easier to key out. It seemed to be a weed of the old hayfield–none in the woods.

I wasn’t paying a lot of attention to birds, but turkey gobbling was coming from two directions when I went into the woods.  They quieted down before 9:30 AM.  Red-bellied Woodpeckers and flickers were making noise and there was evidence on some of the dead trees of Pileated work.  As I was walking alongside the field a pair of Wood Ducks flew over making the distinctive upward-slurred “Ooh-eek.”  I’ve read that it’s the female that makes this call, but the two birds are usually together when I hear

it and I’m not sure that the male never produces it.

And there were Tufted Titmice singing in the woods and Field and Song Sparrow singing at the edges of the field.  And a few more I haven’t listed.

Back Tuesday for our second stewardship work day.

The second work day is Tuesday, April 12, hours 5:30-7:30 PM.

Anyone who has an interest in the sanctuary and its management is invited to join in the effort on one or both dates.

The other two spring workdays are Saturday April 23, 9-11 AM and Wednesday April 27, 5:30-7:30 PM.

The Mildred Harris Sanctuary is located in the southwest corner of F Ave. and 8th St. in Alamo Township, Kalamazoo County.

What we can accomplish depends on how many people show up.  On this first work day of the year, someone should walk the roads that border the 40-acre property and pick up any debris that has built up over the winter.  When Katy and I visited Thursday morning, there seemed to be no major accumulation.

One change last year in our approach to management included brushhogging along the edge of the forest.  The preserve is roughly 50:50 beech-maple forest (west side) and grassland (old hayfield, on the east side). The one place where garlic mustard is abundant is in the areas along the forest edge occupied by dense growths of raspberries and blackberries or multiflora rose.  Large segments of these all but impenetrable thickets have been mowed down enough that they are not quite impenetrable, hence open for garlic mustard control.

One major task that we will begin Saturday will be attacking the somewhat exposed garlic mustard.  This will be by spraying, daubing with glyphosate, and pulling.  The second and third will be done by the volunteers who show up.

Someone can walk through the beech-maple forest looking for garlic mustard plants, which will mostly be visible as basal clumps of leaves.  In the woods itself only occasional individual or small clusters of plants will be found. Flagging any plants spotted can be followed up on later trips by careful pulling with the pulled plants carried away in bags.

In the brushhogged strip along the edge of the wood, the stubs left over from the larger trees and clubs could be lopped off at ground level to reduce the likelihood of tripping and falling by stewards and other visitors and daubed with glyphosate to discourage resprouting.

Brushhogging was also done in the field.  About one-third of the field was mowed last summer.  We will be interested in how many of the woody invaders resprout as the spring and summer go along.  It’s possible that brushhogging one-third of the field every year, so that the whole area is mowed every three years could keep the shrubs and trees stunted enough that the field area remains effectively a grassland.

One more task that we need to tackle sometime this year is the Mildred Harris Sanctuary sign.  It needs, at a minimum, repainting of the routed letters.  A thorough renovation of the sign, including repainting is another possibility.  A third, if there should be a woodworker with skill at routing, would be a totally new sign.

Katy and I will see you at 8th and F Saturday morning and/or Tuesday early evening. Park around the corner on F Ave. Bring work gloves and any tools you favor.  We’ll have some lopping shears, glyphosate, vinyl disposable gloves, and plastic bags.

I first learned of the Harvey Ott Biological Preserve about 1967 from the study of the preserve’s forests by Tony Catana, then in the Biology Department at Albion College.  I have visited the preserve a good many times since, most frequently in the period after the timber cutting regrettably authorized by an earlier Calhoun County Board of Commissioners. In September 1994, I brought my ecology class from Western Michigan University to study the destruction, and over the next several months, directed a detailed study of the logged site by a graduate student.  In 1994 and 1995 I sat in on some of the meetings of the ad hoc committee that produced a management plan and policies for the preserve.  The plan and policies that were developed weren’t bad.  They would make a good starting place for a stricter and more comprehensive document for the future.

My opinion is that a bicycle trail of any sort, let alone a wide asphalt trail, would be harmful to the native plants, animals, and ecosystems of the site.  Damage would come from construction and would continue during later use of the trail.

I also believe that such an intrusion is contrary to stated aims for the preserve in every stage of its history and under every owner.   This includes ownership by Calhoun County.  To finance purchasing the preserve from Albion College, the County  applied for a federal Land and Water Conservation Fund grant.  Its application stated, “The property was originally purchased by Battle Creek College for a nature-biological study area.  The full intent of Calhoun County is to continue with the preservation….”  The Site Management Plan prepared by the ad hoc committee in 1994-1995 stated, “It is the intent of Calhoun County to maintain the Preserve as an area for passive, non-destructive, recreational, educational, and aesthetic use.” In the Plan, bicycling (and horseback riding, among other things) is specifically prohibited.

In my opinion the plan brought forth by the Trailways Alliance was not well designed.  It’s hard to believe that the group has spent eight years planning and promoting the trail without doing environmental due diligence.  Not only have no studies of the Ott Preserve been done, but it appears that no studies have been done anywhere along the proposed route.  What rare plants or animals or important natural features will be impacted?  But also, what contaminated or otherwise dangerous sites would the projected route take hikers through?

I am a supporter of trails.  Rail-trail conversions around the nation have nearly always been environmentally and socially beneficial.  The same can be said about many other sorts of trails–trails that were thoughtfully routed, carefully designed, and competently executed.  I do not consider trails that invade preserved natural areas to be in this category.  In fact, designing a trail by poaching on  protected public or other conservation lands seems to me a disservice to the citizens of the region– as well as showing a certain lack of initiative.  Optimal trail design would include, among other criteria, a route that eliminates or minimizes damage to preserves, parks, and other sensitive areas.

If the choice is between a hard-surfaced trail running through the preserve and no trail, then no trail is the responsible choice without question.

The only compromise I can see that would be respectful of the values of the preserve and meet the clear duty of Calhoun County as stewards of the preserve would be a trail that stopped outside the preserve, perhaps at a bicycle-parking area, also outside the preserve.  From the bicycle-parking area, a short foot trail to the preserve boundary could allow access to the foot trails of the preserve. Providing a way to get to the Ott Preserve without the use of a car is one good feature of the Trailways plan and probably worthy of retaining–but only if the preserve itself is absolutely protected.

Additional comments:  My impression is that the Calhoun County Board has done a good job of listening.  Perhaps they will adopt some sort of compromise position. But there are an infinite number of possible routes between the northwest parking lot of the Ott Preserve and the stoplight on Michigan Avenue (route mentioned in 12.A in the  Commission agenda for 7 April 2011).  Some of these might be almost totally protective of the Ott and some might be damaging.  It would be desirable that the route to be taken should be nailed down and described in any resolution adopted in the April 7 meeting.  Also spelled out should be the principles to be followed for any trail section where the precise route can’t be currently stated (for example, no alteration of existing land contours).

These requirements are essential considering that any construction is likely to be some little time away, probably several years. Public memories dim.  The trail advocates have fought doggedly for their vision of a 14-foot-wide bicycle path down the middle of the Ott. When construction begins, three or four or five years from now, a strong pull could exist toward dealing with any ambiguities in the statement of route by following the “bicycle-trail-through-the-Ott” game plan familiar to the Trailway Alliance and its allies in county government.

The Calhoun County Commissioners will be the ones voting on the trail.  They may give more weight to messages from their constituents; nevertheless, it will be of value to them to know if the threat to the Ott Preserve is a matter of concern to conservationists and nature lovers elsewhere.

Most of the information that follows is from the Say “No” to Pavement: Protect Ott Biological Preserve organization and was supplied by Sophia DiPietro. Comments in italics are mine.  Besides earlier posts at this website, information on the proposed trail through the preserve and its drawbacks are most readily accessible at the Facebook page Say “No” to Pavement: Protect Ott Biological Preserve, especially the Wall and Info sections.

Main Esker Trail, Ott Preserve. Photo February 2011 by Richard Brewer

Last Saturday, I took a walk with about twenty other people at the Harvey Ott Biological Preserve. This is where the Calhoun County Trailway Alliance wants to put a 10-foot wide paved cycling trail. Tom Funke, Director of Conservation for the Michigan Audubon Society, led the excursion. MAS owns about 20 sanctuaries. Tom is a Western Michigan University grad (Biological Sciences and Environmental Studies) who is well acquainted with the Ott Preserve, having spent his immediate post-graduation years in Battle Creek and having been a board member of Friends of the Ott Preserve. The Friends is a non-profit conservation group formed soon after the 1994 timber cutting in Ott but just now being reactivated after a dormant period following several tranquil years at the Preserve. We entered at a parking lot at the south end on land donated  by the Sutarek family as an addition to the preserve after the logging. I was glad to get a chance to walk a part of the proposed trail, though exactly where the trail is  supposed to go needs to be made clearer, at least to me. If I’m reading the available material correctly, the trail goes out of its way to invade the Ott Preserve, potentially bringing traffic whose interest is not the Preserve but mileage on the Calhoun County or North Country Trail. If things go on as they have been, the public may not get a full picture of the specifications for the trail until trail advocates and associated government agencies have settled everything among themselves.  Some comments by the trail advocates seem to suggest–maybe are meant to suggest–that that point may already have been reached.  We read comments like “Both of these entities could pull their funding for the project if the approved route… is changed.” and “If we change the plan or encounter significant delays in implementation, we could lose dollars committed to Calhoun County….” It does seem clear that part of the route in the preserve is projected to follow the existing main esker trail.  We reached this trail after traveling over other sections of the existing foot path, which included an unpaved dirt section, a Trek boardwalk, and an iron bridge.  I’m uncertain what the plans are for these sections of the path.  Are they flat enough, smooth enough, wide enough, and with a strong-enough base to be incorporated in the proposed trail?

Width of the Main Esker Trail, Ott Preserve. Photo February 2011 by Richard Brewer

The main esker trail begins not much past the bridge.  Currently this foot trail–shown in the first two photos–runs on the side of the esker and is less than five feet wide, or in other words, less than half the width of the proposed paved rail.  To the 10-foot paved trail would be added additional 2-foot-wide unpaved right-of-way strips on each side. The resulting 14-foot trail would mean a major remaking of this land. If it actually followed the current trail (which the trail advocates’ literature suggests), a much larger shelf than seen in the photo–three times as wide as shown, maybe more–would have to be cut in the side of the esker.  If, instead, the trail followed the top of the esker, a great deal of grading and filling would be needed to produce a flat, level surface for a 14-foot right of way. It seems clear that much more land in the preserve than just a claimed 2 acres (1.7 miles long X 10 feet wide) would be disturbed in the construction. Eskers are interesting land forms. They are formed toward the front of a sheet of glacial ice at a time when the front is just sitting there or wasting away at the end of a glacial advance.  Running water carrying rocks, gravel, sand, and silt forms channels through the ice–below it, on top of it, or even as a tunnel within it.  The rivers in these narrow. meandering channels deposit the sediments they’re carrying. The result, when the glacier has melted back, are ridges–eskers–of water-sorted, but mostly coarse, material. Aside from damages to the plant cover from construction, the existence and use of such a trail would have continuing harmful effects on the vegetation and wildlife. A broad, paved trail forms a barrier to travel for many small animals, fragmenting their populations. Birds and mammals move away from a trail when people go by, especially noisy people; hence the amount of usable habitat is reduced. Construction and maintenance equipment bring in seeds of invasive plants. Besides these unfortunate biological effects, there are other reasons to be sorry to see the esker whittled away.  It’s a specific habitat for organisms, but it’s also a distinctive landform, interesting in itself. An esker is worth protecting. About forty years ago, the city of Portage refurbished Ramona Park on Long Lake in Kalamazoo County.  One feature of Ramona Park was the presence of a couple of drumlins.  Like eskers, drumlins are glacier-produced hills, but they’re usually small, stream-lined, and symmetrical.  Frequently they’re tear-drop-shaped in outline, in which case the pointed ends show the direction the ice sheet was going toward. In fixing up the park, the Portage park department got rid of the drumlins–bull-dozed them flat and used the till to fill in some low spots.  I’m not sure whether the Portage politicians and bureaucrats didn’t know that the little hills were drumlins or didn’t care.  Possibly they knew very well and flattened them with sincere regret after an environmental assessment and a careful weighing of all economic, environmental, and societal costs and benefits.

Anyway, the drumlins are gone, replaced with playing fields, parking lots, and lawn. I think the citizens of southwest Michigan got skinned.

Preserving landforms–eskers, drumlins, waterfalls, caves, cliffs–is slightly different from preserving ecosystems or flora and fauna, though they go together.  But after all, the land is where Homo sapiens has always lived.  It’s pretty common for certain unusual landforms to be preserved. Waterfalls, caves, and natural bridges usually get protected, one way or another.  There are a few land trusts that specialize in caves, and there could certainly be others that specialize in, say, springs or serpentine soil. But we should recognize that humans have always altered, even damaged, the land they occupy. This includes eskers. Eskers are often associated with swampy or marshy areas, as at Ott, and for as long as humans have lived in the glaciated parts of the world–about 40,000 years for Europe, perhaps 15,000 years in North America–they have probably used eskers, where available, as a dry path.  Almost certainly, the local Indians trod the Ott esker, and there’s no reason for us not to do so still.  But we ought to tread as lightly as possible, not with bulldozers and asphalt.  I expect my ancestors in Europe as well as the Potawatomi here in Michigan walked single file.  That’s probably still good enough for us when we’re in a preserve.

Altering our living space is not a uniquely human thing; every organism does it—pigs rooting up spring wildflowers and buffalos enlarging their wallows are just obvious examples.  The difference between us and other organisms is that we are, or ought to be, aware of the damage we can do.  We can mend our ways rather than wait for destruction and catastrophe to take their toll on us.  Instant gratification without considering environmental consequences is behaving like every other member of the animal kingdom.  Thought which may lead to prudential restraint is what we do that is human.

Preserved natural areas are vulnerable.  I don’t mean they’re delicate.  It’s true that some will need a particular kind of management, such as prescribed fire, and some may not tolerate a lot of human traffic, but good-sized natural areas–a few hundred acres–are often fairly robust.  They’re vulnerable not because they’re fragile, but because there are always certain people who look at preserved land and think it’s not utilized. It’s just empty land, a land bank waiting for their higher and better, destructive use.

The vulnerability is complete when the appetite for a quick, cheap, and easy fix is joined with one more factor:  The organization charged with defense of the conserved land is not up to the job.

We have seen this vulnerability several times in southwest Michigan.  One recent case is the Colony Farm Orchard at Western Michigan University, described in a number of earlier posts at this website.  Land bought with tax-payer dollars was given to WMU by the state with the restriction that it be kept as open space for public use.  But a little more than 30 years later, in 2009, WMU persuaded the Michigan legislature and governor to strip the restriction from the Orchard.  The land is currently open to any kind of development.  Though WMU claimed expansion of their BTR park–to create jobs–as their justification, no such restriction remained in the bill signed by then-governor Jennifer Granholm.

Another example is Jean Klock Park on the Lake Michigan shore at Benton Harbor. It’s a particularly sad case. In 1917, John Nellis Klock and his wife Carrie gave the city 90 acres of coastal marsh and sand dunes, including nearly 3000 feet of lake frontage and beach. It was, as far as I can determine, the first Lake Michigan natural land protected for public use.

Given as a memorial to a daughter who died young, the land was meant to be for the benefit of the people of Benton Harbor but especially for the children.  The city proved a good steward for nearly 70 years. Then, in 1986, the city tried to add a large part of the park to its Downtown Development Authority.  This threat was rebuffed, but another surfaced in 2003 in the form of a proposed luxury housing development.  Although this specific proposal also failed, the settlement reached set the stage for a successful attack within two years in the form of the Harbor Shores development which includes a Jack Nicklaus Signature golf course that has subsumed a large area of the park’s best dunes.

The machinations that resulted in the degradation of Jean Klock Park are probably not yet totally revealed, but even so it is difficult to summarize the operation in a few paragraphs. Several people and agencies that might be seen as having protection of the park and its natural features as part of their job or mission, instead acted to undo the protection.  Among them were the Benton Harbor city commission, Governor Jennifer Granholm (again), U.S. Representative Fred Upton, Michigan’s Natural Resources Trust Fund board, and the U.S. Park Service.  There were, of course, also some conservation heroes fighting the development.

Loss of areas that we have every reason to think of as protected in perpetuity is not restricted to Michigan; attacks are regrettably widespread.  A current example is the pristine Izembek National Wildlife Refuge at the end of the Alaska Peninsula in southeastern Alaska.  The U.S. Congress provided pork-barrel funding to build a 9-mile road between King Cove and Cold Bay, two villages with a combined population of fewer than 900 people.  The road would run through designated wilderness including wetlands that are sites for feeding, nesting, or molting of black brant and Steller’s eider, among other arctic tundra species.   Construction is awaiting an environmental impact statement.

The current attempt to put a wide, paved trail through the best parts of the Harvey Ott Preserve in Battle Creek, Michigan, may not be as globally important as a road in a 400,000+ acre refuge containing wetlands of international importance. But otherwise the situation is fairly similar.

The Ott situation is especially unhappy because Ott has been through this before, about 15 years ago. The Calhoun County Commission sold about 300 trees, mostly large oaks, out of the preserve.  The catastrophe was not as complete as it could have been, because as the result of heavy citizen opposition, the commission canceled a second clear-cut that would have removed the rest of the upland forest in the preserve.

The 1993-1994 Ott timber sale had no redeeming features.  It happened mostly because the Calhoun County Parks Department was broke. On the other hand, a trail for hiking and biking can be a good thing.  (Trails and trail conservancies are given a thorough discussion in chapter 13 of Conservancy: The Land Trust Movement in America.) Certainly the existing foot paths in Ott are, to a point, good things.

One justification I’ve heard for running a trail through Ott is as a connector for the North Country Trail. If a connector is needed, it’s unlikely that a satisfactory route would need to invade the Ott Preserve.  I suspect that Ott has been chosen mostly because those pushing the trail see Ott as being unused, empty, not utilized.

I suspect they also see it as free land.

If the best route–avoiding the Ott Preserve except perhaps for a small spur–would involve private land, private land can be acquired by purchase or the right to use the land as a trail can be acquired as an easement.

Sometimes the right thing to do is a little harder than the expedient one.

It’s possible that a new trail for Calhoun County could be a good thing.  A new trail through the Ott Preserve wouldn’t be.  Ott is utilized.  It’s a preserve.

The Ott Preserve at the east edge of Battle Creek was the subject of an attack several years ago.  The 260 acres had been preserved early in the 20th century through joint efforts of local naturalists and John Harvey Kellogg.  In 1977, Calhoun County bought the preserve using money from the federal Land and Water Conservation Fund.  Fifteen years later, the 1993 County government, ignorant of what the Ott Preserve was about, agreed to sell 305 large trees, mostly oaks from a southern upland section of the preserve.  Battle Creek citizens and conservationists throughout the state protested and the County Commission backed off from a second cut that would have logged the rest  of the preserve.  There is more about the events of 1993 in Chapter 4 of Conservancy: The Land Trust Movement in America.

Serious damage had been done, but the oak forests of the upland ridges (eskers in geological terms) were saved and the wetlands that include the unusual type of vegetation referred to as fen were not seriously damaged.  Now another 15 years has gone by and a new threat has shown itself.  A group has proposed running a wide, paved trail through the preserve.  Part of the justification appears to be to provide a link with the North Country trail.  Pedestrian trails already exist within the Ott Preserve.  Much is still unclear about the current proposal including justification, alternatives, funding for construction, ability to pay for maintenance in the long term, immediate and continuing impact, and acceptability to the citizens of the county and the region.

The following comments on this current threat to the Ott Preserve were prepared by Sophia DiPietro, an advocate for the preserve and member of the Protect Ott Coalition. They were published in slightly different form in the Battle Creek Inquirer Sunday 6 February 2011 with the heading “Ott is natural gem worth preserving.” The Enquirer website includes several useful comments by readers in addition to the article.

Don’t Allow Degradation of the Harvey N. Ott Preserve

By Sophia DiPietro
The nonprofit Calhoun County Trailway Alliance has proposed a nearly $2 million, 14-foot-wide “smooth-surfaced” trail-to-nowhere through the heart of the 100-year-old Ott Biological Preserve, and throughout Calhoun County. The Trailway Alliance says their aim is to “enhance the quality of life and environment for present and future generations.” As an outdoor enthusiast and healthy lifestyle advocate, I am in favor of outdoor recreation; but at the expense of damaging the natural features of Calhoun County’s only preserve? No way!

Ott Biological Preserve is the most biologically diverse and pristine natural area that Calhoun County has. It is a living piece of Michigan’s geologic history. Ott’s unique 10,000 year-old glacially-formed eskers were once the streambeds of ancient rivers. They wind nearly one mile throughout the Preserve. Unlike the existing trail that follows these eskers, the “hard” engineering required to level out inclines, and to cut and dig a “smooth” or paved ten foot-wide trail (with two feet of clearing on each side,) would compromise the esker. In the blink of an eye our rich geologic history will be replaced with the everlasting footprint of heavy machinery. Downslope lies a globally rare prairie fen wetland habitat (fewer than 2000 acres occur in Michigan,) and three spring-fed kettle lakes– former sites of large ice block melts. These sites could receive inputs of sediment via erosion from construction disturbance and from pavement runoff. These vital headwater ecosystems are habitat to state and federally listed threatened plants and animals. They provide us with floodwater control and groundwater supply filtration that enhances our water quality. Ott provides breeding grounds, shelter, and food to mammals, reptiles, amphibians and birds.  Some may not survive, while adaptable ones may become “nuisances” in adjacent neighborhoods.

Ott’s trails are currently used for hiking, jogging, nature photography, birdwatching, snowshoeing, cross-country skiing, quiet reflection and educational studies. Since the first 105 acres were purchased in 1911, the land has been used as an outdoor classroom, especially for advanced college research. The notion that Ott is not used enough is false, and a “preserve” is no place for 10-speed bicycles, skateboards and rollerblades. In fact, any asphalt, gravel, or other “smooth” development of the trails will eliminate cross-country skiing, snow-shoeing and winter hiking in the Preserve, since non-dirt surfaces are not appropriate for these sports. The proposed smooth impermeable surfaces would retain water in puddles, refreeze into ice and create a slip-and-fall danger. This would effectively take the Preserve out of use for the cold months, when many people are even more active in Ott.

Luckily, an alternative route through Ott exists that is more economical, more handicap accessible, and scenic but with fewer negative impacts. Providing an independently conducted environmental evaluation would give this route a green light, the trail would follow an already-cleared Consumers Energy power-line right-of-way along the west boundary of the Preserve, right to East Michigan Avenue. That exit point places you a mere 50 feet from where the Alliance proposes that their trail meet back up with the same exact power lines, right across the street in Kimball Pines! It could incorporate the placement of a currently un-used historic bridge, to cross over a tributary to the Kalamazoo River. The diversity of “edge-loving” species of birds and mammals that inhabit areas between forest and open habitats makes this alternative route rich in wildlife-viewing opportunities. I have bird-watched this route many times, to my heart’s content.

The development of the preserve as currently proposed would have complex and permanent environmental impacts.  Much more is involved than just “how wide” the proposed trail development is, or “what surface” is used. Transforming this peaceful nature preserve into an urban park would make Ott into what every other urban park is: paved, loud and with limited nature experience. And let’s face it, in a county that is recovering from one of the worst oil spills in its history, does it really make sense to develop and destroy the one last remaining public wilderness area we have?

I was happy to accept answers at any level of the environment from “If I don’t build my house in chaparral I won’t get burnt up in the next chaparral fire.” to “I’ll cut down on energy usage, hence CO2 emissions, and I and the rest of us won’t get drowned when we’re living in Miami, Charleston, or Wilmington and the sea level rises.”

Some students got it, but a few didn’t.  For the latter, perhaps ecology was simply a required course, as remote from real life as a class in theatrical costumes of the 17th century.

Just out is an interesting article by two who get it, Jim Armstrong, a poet, and Kim Chapman, an old friend and former student.  Both got a lot of their schooling in Kalamazoo.  The article is called What Laura Saw: Making a Little Home on the Extreme Great Plains. The article is about the Little House series by Laura Ingalls Wilder but puts it in an ecological context.  Ecology turns out to set the social and economic contexts of the Ingalls’ lives also.

The article appears in the recently published Proceedings of the 21st North American Prairie Conference. The conference was at Winona State University in Minnesota in August 2008.

Western Michigan University was host in 1982 to the Eighth Prairie Conference. Kim Chapman, then a graduate student, served as field trip coordinator, poetry contest chairman, and co-designer of the logo.  He was also finishing up his master’s thesis.

What Laura saw around her little house, in Armstrong and Chapman’s words, was “a highly evolved environment, where several thousand years of drought, fire, hail, harsh winters, and intense grazing by ungulates and locusts shaped a responsiveness in plant and animal life that enabled the whole of the environment to persist even as individuals and species disappeared or shifted in abundance and location. That environment was beautiful and hostile by turns and Laura described this in memorable detail.”

The bison and the grasshoppers (the Rocky Mountain locust) were members of this ecosystem.  The locust is now extinct and the bison no longer around as a free-roaming species.  Still extant because they don’t infringe much on human property rights or economics are most of the bird species whose life histories fit them for flourishing in the years of good rainfall and good growth and pretty much moving out in the droughts.  The Yellow-headed Blackbird is an example that I talked about a few months ago.

“The argument threaded through all the books,” Armstrong and Chapman point out, “is that an independent-minded family, pulling together and with a little help from neighbors, could make a living on the Great Plains by their enterprise and hard labor.  As the books progress, however, the reader understands that Pa [Charles P. Ingalls] was not able to realize that dream for his family.  This tension is what makes the books readable today.”

By 1894, Laura and her husband, Almanzo,  had moved to “the well-watered Missouri Ozarks where they lived for the rest of their lives.”  And where Laura and her daughter, Rose Wilder Lane, worked on the Little House books starting in 1930.

The books promote individualism, hard work, and self-sufficiency.  These are admirable traits, but were not enough in themselves to bring success in the unpredictable habitat of the Great Plains.  Even here in the “well-watered” eastern U.S. and, in fact, in the world as whole, we now live in an environment  characterized by unpredictability–largely brought on by our own actions.  Other virtues, especially an attention to the whole ecosystem, human, biotic, and abiotic, will have to be added if success is to be ours.

When I go outside this summer I’m impressed by the amount of greenery.  I don’t have data, but it’s the greenest summer–the largest volume of foliage–I remember.

This makes sense.  The limiting factors for photosynthesis, Biology 101 tells us, are temperature, light, and carbon dioxide.  Translating photosynthesis into plant growth–that is, new biomass–also involves availability of water and soil nutrients, such as nitrogen.

This  growing season has been, day after day, one of the most consistently warm years–hot, I’d say–that I remember.

As for sunlight, I doubt that one summer is a lot different from another. Certainly, day length is the same from one year to the next.  There may be a few more cloudy hours one year than another, but all in all I suspect that the light this year has been about the same as last year or the one before.

Water, though, I think may have been in better supply than usual.  I haven’t tried to check weather station figures, but from my own rain gauge and how often our garden needed water, it seems to me that we’ve had a lot of well-spaced soaking rains.

Nitrogen is sometimes a limiting factor for plants, including several field crops. I don’t know that it was any more or less abundant this year.  Nitrogen compounds from agriculture are generally increasing in the environment.  For some plants an increase in nitrogen could encourage growth; however, many plants have modest soil nitrogen requirements.  Included are many prairie species.  For such species, a lot more nitrogen doesn’t increase production.

However, the compound nitrous oxide is increasing in the atmosphere as a result of current agricultural practice.  Nitrous oxide is a powerful greenhouse gas, so it’s likely that more nitrous oxide is a part of the equation for global climate change in general.

More influential though is the increase in atmospheric carbon dioxide.  As everybody knows, the concentration of carbon dioxide in the atmosphere has gone steadily up, probably since early in the Industrial Age and certainly since 1958, when the systematic recording of atmospheric carbon dioxide began. Lately, the concentration has been rising about 3% per year.  This implies a doubling in about a quarter century, roughly one human generation.

So, maybe high temperatures, lots of rain, and more carbon dioxide than ever made 2010 a banner year. My guess is that the luxuriant growth this year is mostly tied to the warmer summer and the plentiful and effective rainfall.  The carbon dioxide level would have only have changed a couple of parts per million from last year.

However, increased carbon dioxide is probably the primary agent for a great increase in the growth of some plants in the past decade or more.  I’m thinking particularly of the vines, specifically the lianas–vines that can spread across the ground but can also climb trees.  Poison ivy, the several species of grapes, and Virginia creeper are native examples of lianas. There are a number of introduced lianas that are invasives in some natural areas.  Local examples are Asian bittersweet and European ivy.

A little more than twenty years ago, a friend asked me whether I thought that wild grapes were a serious pest in local forests; specifically, how frequently did they climb into the crown of a tree and kill it by shading its leaves?  I had spent a lot of time in beech-maple forests and told him that in my experience such a thing was rare. I went on to say that having a tangle of grapes in the forest canopy had its benefits, among them providing cover for barred and horned owls to hide from crows and blue jays.

No more than five years later my advice would have been different. At least by the mid-1990s, the grapes, Virginia creeper, and poison ivy were creeping up tree trunks in much greater numbers and the trees were suffering.  These trends continue.

Lianas are, of course, a prominent life form in the forests of the Tropics, and it’s possible that their success here in recent years is just one more result of global climate change. But temperatures are erratic.  The general trend in this part of the world is up, but any given year may be unchanged or even down.  Carbon dioxide, by contrast, is a little higher every year. My guess fifteen years ago when I began to notice the increased liana growth was that it was related to increased atmospheric carbon dioxide.  Research in the past few years supports that hypothesis.  This link is to a study of poison ivy.

Despite what’s been happening with the lianas, my impression is that most herbs and shrubs within the forest didn’t join in this year’s burst of growth, not the way plants of the edges and the open spaces have.  Perhaps this makes sense too.  In the forests, the limiting factor for plant growth most of the time is light.  Despite our atmosphere’s extra carbon dioxide, despite this year’s good supply of water and the high temperatures, light at ground level within the forest is dim most of the growing season.  In the oak woods here, sweet cicely, white avens, tick trefoil didn’t look any more robust than they did last year.

It was just an average year in the woods.

The usual way a person encounters columbo is to find one or a group of its basal rosettes.  These look rather like the basal rosettes of the well-known biennial weed common mullein except that the elongate oval leaves of columbo are thin, smooth, and green instead of thick, furry, and silvery like mullein.

Occasionally one sees a columbo flowering stalk.  It’s an impressive sight, often six or even eight feet tall, smooth and green, with several whorls of leaves and a great number of branches in the upper whorls bearing dozens or hundreds of small flowers on slim stems.  Though small, the flowers are striking looking, symmetrical with greenish-white, purple-dotted petals.  Long ago, in southern Illinois, when my friend Kenny Stewart and I found a blooming columbo, he described the flower as looking like a botany text book diagram of flower structure.  Calyx, corolla, stamens, a pistil, all the parts are laid out just as they should be, plus in the middle of each petal, a fringed nectar-producing gland.

Seven years ago, I decided to follow the fortunes of one patch of 121 columbo plants spread over an acre or so of oak woods. Two other patches of similar size exist several hundred feet away, one to the east and one to the west.   Ralph Babcock, a friend and former student, joined me to spend a day marking each plant by means of an orange plastic flag on a wire.  We gave each plant a number, written on the flag using a marking pen with super-permanent ink, and I recorded each location using direction and distance to landmarks and nearby plants. A little later in the summer, we recorded size and other information about each rosette.

Giving each plant an identifying number allows me to follow what happens to each one individually, like birds in a banded population.  Every June, I check to see which plants are still there and their size and condition and to replace weathered and missing flags.

Am. columbo plant number 52. On 23 June 2009, the rosette was composed of 30 leaves and had a diameter of 54 cm. Photo by Richard Brewer

The census usually takes me four or five days, a few hours each day.  Last year I postponed replacing  fading and tattered flags because I wanted to record what other plant species were within a meter or so around each plant and to note something about the topography and litter depth for each point.  So this year’s census took a little longer than usual because I had to make 39 new flags and renew the writing on many others.

As to the plants in the neighborhood, the big trees are mostly white oak, black oak, sassafras, wild black cherry, pignut hickory, and red maple  A few of the herbs are sweet cicely (which went from flowers to fruit just in the week when I was censusing), white avens ( in flower now), Indian pipe (not quite up yet this year), rattlesnake fern, spotted wintergreen, and lopseed.  There’s a fair amount of poison ivy and Virginia creeper on the ground too, more every year.

Some of the birds I hear singing or calling while I work on the columbo are Wild Turkey (pretty quiet lately), Ovenbird, Wood Pewee, Great Crested Flycatcher, Black-capped Chickadee, Tufted Titmouse, White-breasted Nuthatch, Rose-breasted Grosbeak, Blue Jay, Red-eyed Vireo, and Scarlet Tanager.

Other vertebrates are sparse.  A few days ago, I saw something hop close to one of my points and was able to find it and see the cross on its back.  It was a spring peeper back from the ponds a few hundred yards away, where they were peeping and mating in April.

There are plenty of deer, though less in evidence now than most of the year. The deer do not eat the columbo and also avoid stepping on them.  Of course, the rosettes die back above ground in the winter, leaving the crown of the large taproot just below the soil surface, so the deer have no visual clues of the columbo from fall to spring.  The deer do blunder into the orange flags, occasionally dislodging them and often bending the wires.  Nothing else seems very interested in the columbo foliage either–not the chipmunks, fox squirrels or even insects. Most plants show little or no sign of insect damage.

Of the original 121 plants, 11 have flowered in 7 years.  The plant then dies, just like the second-year mullein plant.  Some columbo have died without ever flowering, but many of the original plants are still alive, reappearing year after year as a basal rosette.

So, American columbo looks like it could be a biennial like mullein, basal rosette one year, flowering stalk the next, then gone;  but it’s not.  I don’t know how long columbo takes from germination to flowering here in the oak woods, but it’s a good many years at best.

If you’d like a name for plants with life cycles like columbo you could call them long-lived monocarpic perennials. Long-lived perennial monocarp is OK also. You may think you never heard of such a thing, but you have.  Some species of bamboos and century plants (Agave) act pretty much the same way.  Also a few animals–sockeye salmon and the 17-year cicada, for example.

Saturday 24 April I’m leading a field trip to the Big Island Woods, also referred to as Cooper’s Island.  It’s a trip for the Kalamazoo Wild Ones chapter.

“Big Island Woods” refers to an “island” of forest in the middle of Prairie Ronde, southwest Michigan’s largest mesic (tall-grass) prairie. The village of Schoolcraft was founded just east of the Island.  Of the Island’s original 300 acres or more, about 20 acres now remain.  The site is probably the natural area in southwest Michigan most worthy of permanent protection, for its combination of ecological, botanical, and historic values.

Historically, Prairie Ronde and the Big Island are interesting because of their connection with the earliest settlers in Kalamazoo County (such as Bazel Harrison), with James Fenimore Cooper (whence “Cooper’s Island”), and with Clarence and Florence Hanes, authors of The Flora of Kalamazoo County.

Ecologically, the remnant of the Big Island that survives is of interest because of its unusual species composition, its similarity to prairie groves of Illinois, and several rare plant species.  The forest could perhaps be called wet mesic and has a diverse canopy, despite a windstorm about ten years ago that blew down many large trees.

Probably the most unusual plant species is the white trout lily, known from only one other site in Kalamazoo County.  Two other rare plants are the trees Ohio buckeye and blue ash.  There are, in addition, many other plants of mesic forest and southern swamp forest, including a relatively rich complement of spring ephemerals.

Down trunks and woody debris from the wind storm about a decade ago make travel somewhat difficult in some parts of the woods.

Relatively little work has been done on the biota other than plants.  However, as a wooded island surrounded by agricultural fields and village streets, it could be an important stopover site for migratory  birds.  In less than two afternoon hours on 11 May 1996 three observers found 42 bird species including 14 species of warblers.

The trip will leave from the I-94 car-pool parking lot at Oakland Drive, Kalamazoo, at 9:15 AM Saturday.  Because parking at the field trip site is limited to about five cars, car-pooling is essential.  The field trip will conclude about noon.

Later on, after the trip, I’ll try to write something about what we saw and talked about at Cooper’s Island.

A stretch of chilly weather, especially some cool nights below freezing, has kept spring from racing ahead the way it sometimes does.  This is good; summer is a fine time, but there are lots of things to experience in spring and it’s more fun to have them spread out rather than all happen in a week.

When I wrote my last post, no frogs had been calling as yet, but soon after, the afternoon of 17 March, wood frogs were calling in the small kettles such as the one shown in the preceding post.

Finding another sound to match any animal’s voice is difficult.  But saying that wood frog calls sound like the feeding chuckle of ducks is not a bad comparison. The frog calls are a little louder, I think, and each one sounds quite fervent, unlike the kind of absent-minded noodling of a bunch of dabbling ducks. But the comparison is a pretty good way to give other people an idea of what wood frogs sound like.

I have heard no chorus frogs or spring peepers yet.  We usually think of these two as the earliest frogs here in eastern North America, but some years wood frogs have been earlier in my experience.  I’m not sure, though, that–for whatever reason–peepers and chorus frogs aren’t rarer than they used to be.

Another animal that I believe was decidedly less common the past few months than in preceding years is the white-footed mouse.  I don’t go out and census mice in the woods; I base this impression on how many mice I trap each winter in the house.  The house here in Oshtemo Township is in oak forest. Beginning when the nights start to get cold, the mice start to find ways to get inside.  I trap them with ordinary mouse traps baited with a little peanut butter with a couple of sunflower seeds stuck in the peanut butter or inserted elsewhere on the trigger of the trap.  Most winters I trap a couple of dozen white-footed mice.  This winter I caught a couple of mice early on and then no more through most of November, December, January, and February.  I also set traps in my house in the southeast part of Kalamazoo County, in beech-maple forest.  Most years I catch several mice through the winter, but this past winter only a couple.

I don’t know what may have happened to the mice this winter and I don’t know whether it’s temporary or a permanent decline.  Next fall and winter may give me a clue.

But that’s getting ahead of ourselves.  It’s early spring.  The wood frogs are calling.  In the beech-maple forest, harbinger of spring, our earliest spring wild flower is finishing up (a blog called Kalamazoo Seasons has a nice photo of the flower). The very first spring beauty flowers have opened. Wild leek is up.

And the little annual Floerkea proserpinacoides with its pale-green narrow leaflets is spread profusely over the ground in the few woodlots where it occurs, but is not quite in bloom yet.  This odd mesic forest specialist deserves a better vernacular name than the obscure, bookish “false mermaid weed.”  Maybe we need a contest for a new, better-fitting name for it.

Anyway it’s spring and will be for a good month yet, maybe longer.  Let’s enjoy it.

Spring began in southwest Michigan in the past few days.   One sign has been the Sandhill Cranes overhead, giving their loud rattle.  They could be on their way north or they could be local birds; several pairs now nest in Kalamazoo County.

Because snow cover was so continuous, and thick, some birds that are usually here by February were mostly delayed into early March.  The cranes are one species, Red-winged Blackbirds are another. I saw my first redwing a few days ago and they’re now pretty well scattered over the countryside.

In Pavilion Township Saturday, Song Sparrows were singing, Horned Larks were on territory in the open fields, and sailing overhead was my first Turkey Vulture of the new year. First in Michigan anyway; we saw Turkey and Black Vultures every day in Costa Rica. Most were probably resident there, but some could have been wintering birds from North America. This morning I saw my second Turkey Vulture sailing above West Main in Oshtemo Township.

I haven’t heard any frogs calling yet, and chilly as it is I don’t expect any tonight, but warmer weather is predicted for tomorrow.

As soon as bare patches began to appear around houses, the early spring bulbs were visible, some flowering.  I’ve already seen winter aconite, snow drops, and crocuses in bloom without hunting very hard.  Our native early spring wildflowers grow mostly in the mesic deciduous forests, and many of them are spring ephemerals–they come up, bloom, and then die back, so for most of the year they’re invisible above ground.  Right now the beech-maple forests probably have harbinger-of-spring in flower, and in the wooded low spots currently occupied by temporary vernal pools, skunk cabbage flowers will be out, though perhaps not producing pollen quite yet.

Our native early spring flowers take advantage of the brief window of full sun that opens between the arrival of warmer weather and the closing of the forest canopy by sugar maples.  It would make sense that the cultivated spring bulbs we buy and plant might be the early spring flowers from the deciduous forests of other parts of the Earth, but that isn’t the case.  Rather, most of the spring bulbs blooming in our front yards come from the steppes or the alpine and sub-alpine meadows of the Middle East and Asia.

The seasons follow one another in a continuous cycle.  A year has no natural beginning and no end.  Several groups of ancients gave the winter solstice, around December 21, special significance because it was the day they were reassured that the sun was actually coming back for another year. Our New Year’s Day, January 1 is arbitrary but since it comes not too long after the solstice, it’s not wholly unsatisfactory as a starting point in the cycle.

To me, though, the first definite signs of spring in nature, the sorts of things that have happened in the past week or so, feel like the engine of the year starting up.  In our temperate latitudes, this is the start of the year’s organic production; photosynthesis really gets underway, storing sunlight that, passed on along the food chain, runs nearly the totality of the living world. For a high percentage of the creatures here, spring is the time for beginning reproduction as well as production.  Eggs hatch and babies are born, and young of the year having new combinations  of genes not quite the same as either parent go out to become part of a later generation–or not.

Spring has arrived in southwest Michigan–I think–and a new year has started.  Happy New Year!

Katy and I just returned from two weeks in Costa Rica.  As part of an Elderhostel–though the program is now called Exploritas–we visited five sites ranging from mangrove forest along the Pacific Coast to the rather chaparral-like vegetation called paramo around 11,000 feet above sea level on Cerro de la Muerte.  Included were visits to several important conservation areas, including  La Selva (and Selva Verde) and a site in the Savegre River valley.

Spending eight or more hours a day in the field, our group identified, or had identified for it, about 280 species of birds.  On one night excursion we heard and saw the Common Pauraque (but no potoos).  We also saw 2- and 3-toed sloths, howler monkeys, collared peccaries and a few other mammals plus various herp species including crocodiles and caimans, 2 species of iguanas, several other lizards, a few frogs, and the cane toad, native here but with a bad reputation in places where it has been introduced, like St. Croix, US Virgin Islands.

Interest in resource conservation is high in Costa Rica.  For one thing, ecotourism, which is what we were participating in, is a major element in the nation’s economy.  The subjects of ecotourism’s costs and benefits and how sustainable it is are complex, but as an incentive for setting aside natural lands, the impact has been positive and powerful.

I’ll write more about our observations and experiences.  For now, I’ll say just that they involved a lot of interesting and beautiful wildlife and plants, spectacular scenery, lots of good food, and good company.

We need to recognize three aspects to the conservation value of this piece of land.  One is what’s good about the land itself.  Two is its beneficial effects on the adjacent Asylum Lake Preserve, which Western Michigan says is permanently protected.  Three is the broad question of how the conversion of this dedicated conservation land to commercial use affects the status of conservation land all across the state.

1. The Land Itself. Although this land has been referred to as the Colony Farm Orchard, the old orchard amounts to only a quarter or so of the approximately 53 acres. The fruit trees are surrounded and in some cases overrun by grape vines.  Box-elder is a common invading tree in the orchard.

The rest of the property is varied habitat with a couple of sizable wooded areas at the north and south ends.  Grasslands dominated by smooth brome grass and goldenrods with invading shrubs and trees surround the wooded areas and the orchard.  The land of the wooded area at the north runs down to a springy area with a couple of ponds.

One part of the conservation value of this piece of land is what used to be here.  The east edge of Genesee Prairie, one of the eight tall-grass prairies in Kalamazoo County, extended to the Orchard site.  This is now the only part of Genesee Prairie in public hands and with any approach to natural vegetation.  The rest is gone, beneath US-131 or occupied by the west edge of Western Michigan University’s BTR park and commercial and residential areas and croplands west of US-131.

It’s unlikely that much of the original prairie flora is left at the Orchard site.  However, there are still bur oaks–a good many, some fairly large and old, others young.  They are all almost certainly descendants of the bur oaks that were part of the savanna fringing this tall-grass prairie. They are a genetic connection extending back 180 years to when the first settlers arrived to homestead on the prairies and savannas of Kalamazoo County.  But the connection extends back much further than that, to long before Europeans reached Michigan or North America, probably to some time in the Hypsithermal interval around 9000-6000 years ago.

As for animals, we know from various sources that there are coyotes, deer, turkeys, woodcock, Red-tailed Hawks, Green Herons, and many smaller birds in the summer or year-round.  I will shortly put up a list of summer bird species that several observers are supplying.  The spot also has all the attributes of an excellent migratory stopover site for land birds in both spring and fall.  As to the small mammals, reptiles, amphibians, insects, I think it may be time for WMU to fund a serious study to find out just what is here.

2. Benefits to Asylum Lake Preserve. The Colony Farm Orchard is properly part of Asylum Lake Preserve.  From the edge of the Preserve vegetation to the edge of the Orchard vegetation is about the same distance as between third base and home plate on a baseball field. The Orchard makes the preserve a larger sanctuary by about 20 percent.  This is good; bigger is better in sanctuaries, mainly because local extinction of species is rarer on bigger sanctuaries.

We could also think of the Orchard as an island near to the Preserve. It serves as a stepping stone that wandering animals not currently living on the Preserve can find and, from there, reach the sanctuary.  The end result of all  this is that the Orchard makes the Asylum Lake Preserve more diverse and less prone to fluctuations in populations, hence more stable.

There are of course the other beneficial effects of buffering against the noise, noxious fumes, and bright artificial lights coming from US-131 and the commercial land beyond it.

3. Threats to Conservation Land Elsewhere in Michigan. The Colony Farm Orchard has a protective conservation covenant that many Kalamazoo residents now know by heart: “The conveyance shall provide that Western Michigan University may utilize the property solely for public park, recreation, or open space purposes, except that the legislature, by statute, may authorize Western Michigan University to utilize the property for some other public purpose.” The restrictions were placed on the land by the legislature at the time of its transfer from the state to WMU in 1977.  If Representative Jones (D-Kalamazoo) and WMU can persuade the legislature to strip away this restriction, as  HB 5207 provides, and if Governor Granholm signs it, WMU will be able to use the land for anything.  This land, bought with taxpayer dollars and now designated for public use–specifically some variety of public open space–would be available to use as an Annex to WMU’s BTR park.  But it could also be used any other way WMU chose.

If HB 5207 is passed and signed into law, what state or university land dedicated for conservation–or any kind of public use–is safe?  What of the state parks? What of the arboretums, botanical gardens, and natural areas of the rest of the Michigan public universities?

What, in fact, of conservation easements?  These are now the most popular way to protect land in perpetuity, widely used by land trusts and government agencies.  They are discussed in many places in Conservancy: The Land Trust Movement in America but especially chapters 7 and 8.  Very briefly, a conservation easement is a binding agreement that permanently restricts the development and future use of land so as to protect its conservation values.  Conservation easements are held by conservation organizations or units of local, state, or federal government.  The easement holders are charged with defending against violations of the easement provisions. As of 2005, land trusts in Michigan held conservation easements on about 55,000 acres.  The amount of land in conservation easements held by government agencies is hard to determine but substantial.  Conservation easements are a relatively new way to conserve land, rarely used before 1960. Most states have statutes providing the legal foundation for conservation easements; Michigan’s is Act 451 of 1954, called NREPA.

But we have seen what the state legislature, or the House at least, has done with statutes in the case of the Colony Farm Orchard.  Suppose some well-connected land owner found that a conservation easement held by some land trust had become inconvenient to him.  Might the Michigan legislature be willing to pass a statute saying the conservation easement on his land was rescinded?  Maybe, maybe not.  Suppose that this situation came up two or three times.  Might the Michigan legislature decide that NREPA as currently written was becoming an unnecessary burden to worthy land owners who had changed their minds about the easements on their acreages.  In that case, might the Michigan legislature amend the statute to make backing out easier–like, for example, by coming to the legislature with what seemed like a good argument, such as using the land to create jobs?  Maybe, maybe not.

The land owners might still have a few hurdles remaining, with the IRS for example.  But that’s what attorneys and accountants are for.

If the legislature did either of these things, a judge or two or more would decide whether what the legislature did was legally OK.  Probably the judges wouldn’t say whether it was right or wrong or how much it damaged the cause of land conservation.

It is a dangerous path that Representative Jones and WMU are trying to steer the Michigan legislature towards.

Spicebush, late October, Oshtemo Township, Section 9. Photo by Richard Brewer

Wetlands are scarce in Oshtemo Township.  Its thirty-six square miles are mostly high and dry and the soils are mostly well-drained.  A few kettles exist in the moraine-outwash plain topoography.  These are depressions formed when ice blocks left behind during the retreat of the last Pleistocene ice sheet melted.  Most kettles in Oshtemo Township don’t hold water today.  A few do some or most years; perhaps a clay lens lies somewhere beneath them, or perhaps enough clay occurred in the surrounding glacial drift to form a more-or-less impermeable layer when it eroded into the kettle.

The kettles that hold water year round or for a few months in the spring tend to have a buttonbush swamp at the bottom; some have a band of spicebush up the bank from the buttonbush.  These are features of some of the sites disturbed least by agriculture and other human activity.

A small triangle of swamp forest is still present in the northwest corner of Oshtemo Township, but several wetland vegetation types that occur elsewhere in Kalamazoo County don’t seem to be present here.  I’m unaware of any examples of open bog, bog forest, sedge fen, or prairie fen.  Possibly small patches of some of these might have been here at the time of settlement.

Early this November I started noticing a good-sized tamarack tree in the wetland at the west edge of the Lilian Anderson Arboretum (Section 15) as I drove by.  It was only 10 0r 15 yards south of West Main (M-43).   At this time in the fall, tamarack needles turn a gold color, so the species is easily spotted.  I finally stopped by on Saturday 14 November, by which time many of the leaves had fallen and the few remaining ones were dull brown.

The situation where the tamarack is growing is consistent with the possibility of fen.  The site is at the base of a slope where ground water feeds the sizable wetland northeast of Bonnie Castle Lake.  However, I haven’t noticed fen plants at other places along the edge of the wetland on many other visits to the Arboretum.  I walked around near the tamarack, but I was just wearing short leather boots and couldn’t get very far out. I didn’t see any obvious fen indicator species, but this isn’t not a good time of year for botanizing anyway.  I’ll have another look or two next spring and summer.

I’ll also make a point late next October of driving around the other wetlands in the township to see if more tamaracks are evident.  Clarence and Florence Hanes found tamaracks in the Twin Lakes area which is right next door to Oshtemo, but nearly all the Twin Lake low ground is across the line, in Alamo Township.

Walking back up the wooded slope above the wetland at the Arboretum, I saw a few spotted wintergreen plants (also called spotted pipsissewa).  It’s a small plant, handsome with dark green leaves with a whitish line running along the midrib.  The line is often rather jagged looking where the pale coloration runs off varying distances along the side veins. The leaves are evergreen and were peeking through the fallen oak leaves. A good share of the oak areas in Oshtemo Township that weren’t cleared still have the species, though I’ve never seen it abundant.  A plant or two or small patches pretty widely scattered is the way it usually occurs. Its geographic range is basically eastern North America, in most parts of which its occurrence is much the same as here–never common but seemingly not in serious trouble.

As we all know,  HB 5207  put forth by Representative Bob Jones (D–Kalamazoo) is designed to strip the conservation/public use restrictions from the Colony Farm Orchard as a first step in turning the 54 acres into an Annex to Western Michigan University’s BTR Park.  Here are the stated restrictions: “The conveyance shall provide that Western Michigan University may utilize the property solely for public park, recreation, or open space purposes, except that the legislature, by statute, may authorize Western Michigan University to utilize the property for some other public purpose.” The bill, introduced in mid-July with no public notice, made its way quickly to the Senate but there progress has slowed.

This delay has given conservationists and other opponents of the measure a chance to make their views known, and they have done so in large numbers.  As of now, we cannot know what will happen.  But we should talk about what ought to be done with the property as conservation land.  I made a start on this subject earlier and concluded that the best role for the land was exactly what it’s doing now, but better.

In that post, I discussed some important ecological functions of the Colony Farm Orchard.  I won’t repeat them in detail, but here’s a quick list.  It’s worth taking note that all these would be diminished or lost altogether by development as a BTR installation.

Many are beneficial effects that the Orchard exerts on the Asylum Lake Preserve, such as

• Reducing noise from M-131

• Filtering noxious fumes from trucks and automobiles on M-131

• Reducing artificial lighting coming from M-131 and buildings across the highway to the west.  Research on the dangerous effects that bright artificial lights have on insects, bats, amphibians in the breeding season, and other forms of wildlife is accumulating rapidly.

• By serving as a very near island of similar but not identical habitats, the Orchard adds species, lowers extinctions and enhances immigration, all of which lead to higher biodiversity and ecosystem stability at Asylum Lake.

Other positive conservation roles the Orchard plays, not necessarily involving the Asylum Lake Preserve directly, include

• Allowing for the presence and reproduction of  shy animals, such as foxes and American woodcock, that are likely to be disturbed on the more heavily visited Asylum Lake Preserve.

• Serving as a migratory bird stopover site well-supplied with cover, water, and food supplies in both spring and fall.

• Preserving land within the historic  Genesee tall-grass prairie and the adjacent bur oak opening.  Perhaps few herbaceous species survive from those pre-settlement plant communities, but numerous bur oaks of various ages and sizes are present that are almost certainly descended from the oaks of the original savanna.

This is just a good start on a listing of the conservation values of the Orchard.  There are, for example, the marvelous asparagus patches along the west edge.  Not for nothing was Euell Gibbons’s first book named Stalking the Wild Asparagus.  “When I am out along the hedgerows and waysides gathering wild asparagus,” he wrote, “I am twelve years old again and all the world is new and wonderful as the spring sun quickens the green things into life….”

There are also the old trees–horse chestnut, tulip tree, maples–planted by the original farm family or by the staff or patients of the Colony Farm.  Big and open grown but surrounded now by many trees of smaller diameters, these are probably what suggested the “Enchanted Forest” name to the Facebook Group.  They ought to be kept as a way of conserving human history as well as natural history.

Then there is the carbon sequestration that has gone on and is going on in the accumulation of tree biomass, which acts to temper the greenhouse effect and slow global climate change.  Turning this land into a BTR park extension would almost certainly mean cutting most of the trees and brush and releasing the stored carbon into the atmosphere as carbon dioxide  either by burning or by the slow fire of decomposition.

It’s not possible yet to come up with a complete conservation design, but here are some things we might want to do when the Colony Farm Orchard is devoted to conservation.

1. Construct a self-guided loop trail going through the property’s major habitats with the trailhead on the east side of the property next to Drake Road.
2. Next to the trailhead, construct a small bicycle parking space.  Too much space for automobile parking has already been subtracted from the Asylum Lake Preserve to allow more to be lost for auto parking here.
3. Provide for safe passage of pedestrians from somewhere south of the Asylum Lake parking lot at the top of the hill on Drake by means of pedestrian on-demand lights, or an overpass.
4. Stop the dumping of leaves and yard waste from Kalamazoo.  It’s a public service of a sort, but on a parcel of only 54 acres it takes up space that ought to be available for natural revegetation or restoration.  The area of thick leaf mulch can be seen in one of the fine low-level aerial photographs of the Colony Farm Orchard by JaySeaAre. Locate the metal pole barn (“Butler building”) on the west border (toward the highway); the heavy leaf mulch is the unvegetated area east of the Butler building and running south toward the electric substation and north toward the old orchard. Several years accumulation are involved, ringed with rank growths of barnyard weeds.
5. Erect a signboard facing M-131 that says something like this: 

Asylum Lake Preserve of Western Michigan University

A sanctuary of 320 acres protected for all time

that by education, research, and as green and open space

benefits the public and the Earth

Before describing what the trail could be like, it’s worth considering why we need a trail at all. People who are highly enough motivated have always made their way onto the Orchard for bird-watching, asparagus hunting, photography, and contemplation. And no trail is needed for the Orchard to continue its services to the Asylum Lake Preserve.  But there are good reasons for the trail: One, it will make it much handier to visit the site, especially for education–classes, but also groups interested in natural history, and any strolling autodidact.

Two, if the Orchard is left as is, there will be those who say, as some connected with WMU have said,  that the land is not utilized.  Of course, the charge was and is bogus. But the trail is one way to demonstrate utilization.  It will show  most people that the land is utilized, though perhaps not that segment of humanity for whom the only meaningful way a piece of property can be utilized is to generate income.

What should the trail be like?  I’d say most of it should be narrow, just wide enough for one person to walk comfortably, and unimproved.  No dogs, I’d say.  It’s nice that people can walk their pets on the Asylum Lake property, but the Orchard ought to continue to be a dog-free refuge, a place for the woodcocks and turkeys and other ground nesters.

There would be plenty to see along the trail, including many of the features already mentioned.  Any trip would find dozens of things to look at and discourse on, as the changing seasons brought forth something new every day.

The trail should loop through the south part of the WMU Foundation property.  In fact, I’d say that the south half of the Foundation land ought to be reunited with the Enchanted Forest. The eight acres extending up to Stadium Drive were regrettably severed from the Orchard property in 1957 and sold into commerce.  The Foundation did Kalamazoo a service by acquiring it in 2007.

Having the trail run through the south part of what is now Foundation property would include a small pond and the ducks and aquatic life that could be seen there and also an area of great hydrological interest as the main source of ground water flow into Asylum Lake.

These are just some ideas of mine. I haven’t discussed them in detail with anybody.  No charette was held.  Nobody paid me a consulting fee; my work was all pro bono publico.  Publico has been given short shrift in WMU’s proposals for the Orchard, so I’m glad to bring a little of it back.

Will the Colony Farm Orchard be allowed to fulfill these conservation aims?  That depends on the Michigan Senate, or perhaps Governor Granholm.  But, of course, it depends most of all on Western Michigan University, which could at any time, decide to let the Orchard live up to the purposes for which it was conveyed from state to university in 1977.  That WMU has not already asked the Michigan legislature to withdraw the section of HB 5207 dealing with the Colony Farm Orchard reveals an anti-conservation, anti-environment, anti-sustainability mindset that may foretell a troubled future.

We had no breeding redstarts in the vicinity this summer, so this was most likely a migrant. Perhaps Katy and I would have done to well stay home and see what else had arrived, but today was a holiday, hence worth a small excursion.

We drove to the West Lake Preserve in Portage.  It has trails, including boardwalks (of green plastic) that run out into marshes east of Westnedge Avenue. The marshes have some cat-tails but are mostly sedges plus a great variety of other herbs and a few shrubs.

Button-bush is the most common large shrub.  It’s distinctive, easily identified with its whitish ball-like inflorescence in summer which remains ball-like in fruit but turns a rosy color.  Easily identified, as I said, as long as you find it in wet ground and it has flowers or fruits.

Once at the Michigan Nature Association’s Black River Sanctuary near Breedsville, the sanctuary steward showed me a large shrub or small tree on dry ground–though not far from the river.  It had no flowers or fruits and puzzled both of us for a while.  Having finally identified it, I think I’ll know it in the future even if it has no flowers or fruits. The fact that it has neither alternate or opposite leaves but instead often has three at a node is a quick first clue.

We were hoping for migrating warblers and other small birds, but the first birds we heard were two Sandhill Cranes.  They were coming from the south and we heard the rolling rattle they make while flying a minute or so before they came in sight over the trees behind us.  They might have been planning to land in the large patch of marsh through which the boardwalk runs if we hadn’t been there.

As it was, they flapped a little harder, regained altitude, passed over a line of trees and came down out of sight ahead of us. Not long afterward, a Great Blue Heron, another big bird though not as big as the crane, flew in from the east.  It did park in the patch of marsh we were passing through, but out of sight in a strip of water on the far side.

It turned out that we saw and heard only a few song birds.  The birds that bred here this year are mostly quiet, some still completing their fall molts.  A few Red-winged Blackbirds were still noticeable in the marshes.  The largest concentration of birds we saw was in a black gum tree.  Its leaves were already red and the ripe dark blue fruits were being visited by a good many largish songbirds.  We saw Blue Jays and catbirds, but may have missed other species.

Relatively undisturbed wetlands are always interesting botanically. There are often a lot of species, and some are in groups that present some identification difficulties. But the set of species that can handle really wet ground and especially standing water is circumscribed.  You don’t have to look through the whole plant manual to identify hydrophytes; instead you can pretty much confine your search to the specialized books on aquatics.

I don’t know what the best such manuals are today.  I still have a copy of Norman Fassett’s  A Manual of Aquatic Plants from 1957 and it serves the purpose.  A little updating of scientific names may be necessary, but that could be true if you use a manual published six months ago.

Several plants were blooming in the marshes.  In fact, flowering late in the season characterizes the wetland flora.  Among plants in flower were pickerel-weed with blue flowers, white-flowered arrowheads, and yellow-flowered bur-marigolds.

The water level was lower than we had seen in recent years, when it had come up to or over the flexible boardwalks.  Bladderworts were growing and flowering on the exposed peaty surface alongside the boardwalks.  They were tiny plants. Some species of bladderworts have purple flowers and some yellow. These plants had tiny bright yellow flowers.  I thought they might be Utricularia gibba, but I wasn’t in a serious plant-identifying mood today.

We continued to where the boardwalk loops back to the dirt path and followed that to the boardwalk that runs out into the sphagnum bog fringing West Lake.  The flora of bogs is even smaller and more specialized than most other wetlands, but includes many striking and beautiful species that can be seen in no other habitat.  The West Lake boardwalk is probably the best local opportunity to see this community with such things as tamarack, leatherleaf, cottongrass, pitcher plant, and sundew.

After the bog, we hiked back out to the parking lot.  It was 12:30 and we had plans to continue our holiday with lunch at the Lebanese buffet.

From statements by Western Michigan University’s PR guy, we know what WMU thinks the Colony Farm Orchard is good for–expansion of the University’s business park.

The motivation for such an action is unclear, as are the need for it and what the expansion would involve. But none of these needs to concern us here.  We want to talk about how the property ought to be used, in keeping with the restrictions on the land contained in the original transfer to WMU in 1977.  Public Act 316 (Sec. 1.2) said

The conveyance shall provide that Western Michigan University may utilize the property solely for public park, recreation, or open space purposes, except that the legislature, by statute, may authorize Western Michigan University to utilize the property for some other public purpose.

The Colony Farm Orchard is at the upper left in this diagrammatic map which appears on the WMU website

To situate ourselves, the 54-acre property lies across Drake Road from the main body of the Asylum Lake Preserve.  The right-of-way for the expressway US-131 is the west boundary, Parkview Avenue is the south boundary, and Stadium Drive is the north boundary.  Actually, nine acres just south of Stadium Drive is owned by the Western Michigan University Foundation (the old trailer park land) but evidently would be included in the Business Park expansion, bringing the total to about 63 acres.

WMU has done very little with the land.  It allowed Consumers Energy and other utilities to use land for the very visible transmission installations in the southwest corner.  These service the current business park, but whether it was wise or prudent to use part of the protected Colony Farm Orchard for them is debatable.

Also, a large leaf composting operation for part of the city of Kalamazoo is located a little north of the utility transmission facilities.  A large-scale composting operation is better environmentally than landfilling yard waste, but whether this use meets the public park/recreation/open space criterion is doubtful. The utility installation and composting operation each have separate service roads coming in from Drake Road.

We should also mention that Michigan State University holds a lease that provides that its Department of Entomology has use of the orchard for as long as it “conducts experimental fruit pest research on the land.” (In preparation for selling the property as part of its business park operations, WMU has indicated that it will pay MSU up to $985,000 to cancel the lease.)

WMU’s main action in recent times has been to erect a fence along the Drake Road boundary making entrance difficult for anyone not willing or able to climb over it.  Access from the south next to the big Consumers Energy facility is possible–and perfectly legitimate since the justification for WMU having the land is, as we know, for public park, recreation, or open space.  But many people, seeing the fence and the locked gate at the composting entrance, would conclude that WMU wanted to prevent access to the property.

The role I’d like to see this property play is exactly what it’s doing now, but better.

What it’s doing now is, for one thing, buffering the main body of the preserve from the noise and noxious fumes of the expressway. That’s good, but it’s not the land’s most important function. The land functions ecologically as an integral part of Asylum Lake Preserve.

The Declaration of Conservation Restrictions adopted by the WMU Board in 2004 says that its first goal is to promote ecosystem integrity by, among other things, maintaining the Preserve as green space and wildlife habitat and protecting natural features from further degradation.  The existence of the Colony Farm Orchard next to the other property contributes to this goal.

The Asylum Lake property itself is not large.  At one time it was 274 acres, but that was before land was carved out for widening Parkview and Drake, for sidewalks on two sides, and for parking spaces. Biodiversity, the number of species, is strongly dependent on the size of a preserve. The Colony Farm Orchard site only a few tens of feet from the Asylum Lake property effectively adds 63 acres, bringing the total size of the protected area to something on the order of 320 acres.

How does adding these 63 acres add diversity? One way is by adding new habitats.  The old orchard itself, a dense thicket type of vegetation, is different from any vegetation on the east side of the preserve.  Also the area of springs lying partly on the Orchard property and partly on the south portion of the Foundation property is a different and rather unusual habitat.

Biodiversity on a preserve is lowered by local extinctions of species and raised by immigration of individuals of new species. Simply the additional acreage is important in preventing extinctions–or reversing them. Suppose that all three breeding pairs of the black-capped chickadee, a year-round resident on the Asylum Lake Preserve, die one winter from some combination of causes and their offspring also disappear by dispersing elsewhere or by death from predation, starvation, etc.  One species has been lost from the preserve.

Now suppose that on the combination of Preserve plus Orchard we start with six pairs.  The chance that all six and all their young will be lost in the same winter is perhaps half the likelihood that three will disappear.  Next year, the survivors may be able to breed and thrive and replenish the chickadee population.  This replenishment, or rescue effect, is an important way in which species diversity is maintained on larger preserves or ones located in close proximity to one another.

This is the role in biodiversity that the Colony Farm Orchard plays–not just for birds, but mammals and insects, turtles and frogs, and other organisms. It’s possible that the WMU business park may also function in this same way interacting with the restored grassland on the southwest side of the Asylum Lake Preserve for grassland birds–though probably not for birds of other habitats.

Another effect that the Colony Farm Orchard enhances is the role that the Asylum Lake Preserve has as a migratory stopover site.  Retaining habitat where migratory birds can rest and refuel on their migratory flights south and north is a new focus in conservation.  Recent studies have looked at what traits make good stopover sites.  For fall migration, fleshy fruits–eaten in late summer and fall even by insectivorous birds–are favorable.  The old orchard has these in abundance in the form of grapes, blackberries, and others.

For spring bird migration, insects, especially such forms as midges hatching from ponds and streams are important food sources.  The springs and spring-fed pond at the north end of the property would provide this steadily renewed food for the northward migrants.

Young acorns on bur oak at Colony Farm Orchard August 2009

The Orchard property has other habitat features that add to its value as a part of the Asylum Lake Preserve.  I’ll mention only one more here.  The western part of the property was within the historic Genesee Prairie.  The rest of it was bur oak plain, a closely related community.  This tells us that the spring area lying at the north end of the Orchard and the south end of the ten acres owned by the WMU Foundation was almost certainly prairie fen. In years of low water in the past, I have identified fen plant species in the wetlands at the west edge of Asylum Lake directly opposite. Prairie fen is a remarkably attractive and diverse ecosystem that The Nature Conservancy and the Michigan Natural Features Inventory have given high priority for protection in Michigan.

It would make good conservation sense to restore tall-grass prairie in a wide band along the western fence of the Orchard property and to restore prairie fen on the springy wetlands at the north.  Southwest Michigan genotypes of plants should be used.

I’ll try to make other specific suggestions as to how the land might be used in a later post.

Bur Oak at the Colony Farm Orchard, a protected area threatened by expansion of the WMU Business Park

Following are brief descriptions of the major vegetation types in Oshtemo Township (Kalamazoo County, Michigan) about the time of settlement. This is the second and concluding installment of a talk given at the March 2009 meeting of the Oshtemo Historical Society.

Information is also provided about what settlement, agriculture, and development have done to original plant communities.  Some protection and restoration possibilities are mentioned under “Current Status.”  Major invasive species are listed. Invasives are plants or animals, usually non-native, that invade and spread, usually at the expense of native species.  Control of invasives may be necessary for conservation.

1. Oak Savanna and Oak Forest (together occupied 88% of Township)
These are treated together because they are similar except for crown coverage.  Areas where the canopy coverage was more than 50% are termed forest.

Tree species–The widespread oak savannas that the settlers usually termed “openings” were dominated by white oak.  Chinkapin (yellow chestnut) oak, bur oak, and hickory (mostly pignut) were  present but not common. Black oak was also present but was common only on the driest soils and was often associated with dry sand prairie. Shrubs included flowering dogwood, hazelnut, New Jersey tea, and shadbush.

Herbs–A great variety, depending on the specifics of the site and also its fire history.  The species ranged from herbs we would now think of as mesic prairie species to ones that now are mostly in forest, even beech-maple forest.

What happened to it?–Much of it was cut over for timber and charcoal which was used in large quantities by blacksmiths. Large areas were also cleared for agriculture, including orchards. More recently remnants are being lost to residential development.  Sites not cut over became brushy and denser owing to invasion of other trees and shrubs in the absence of fire.

Current status–No intact examples are left, but a fair amount of land exists occupied by more or less disturbed remnants.  In the past 30 years these have been heavily invaded by red maple and white pine.  Both species were almost absent from uplands in 1830.  Because of the dense shade these trees cast, less shade-tolerant herbs and shrubs are reduced.  To provide a demonstration of what most of the township was originally like, a few sites of considerable acreage should be set aside. Invading maples and pines should be removed and a continuing fire management regime should be started.

Invasives–Tartarian honeysuckle, Common privet, garlic mustard, dame’s rocket, and recently money plant.

2. Other-than-mesic Prairie
These prairie types ranging from wet to dry mostly tended to be associated with oak savanna on sites of appropriate soil moisture and fire history.

For example, on south- and west-facing slopes especially next to lakes or broad valleys occurred hill prairies, also called goat prairies.  These shared some species with the adjoining forest or savanna and some with other prairie types; they also had a few distinctive species.

Wet prairie occurred on lowlands associated with wetland herbaceous communities.

Current status–Few if any sites left because of development and absence of fire; any sites that contain a sampling of the characteristic species are worth preservation.  Searches should be made of the appropriate slopes for hill prairie remnants and of the few wetlands for wet prairie species.

3. Mesic or Tall-grass Prairie (Grand and Genesee Prairies were 2% of Township)
Tree species–Mesic prairies were treeless.  Bur oak might occur at the edge.

Herbs and grasses–Big bluestem and Indian grass were the most important tall grasses, but several other species of lesser stature were present.  Important herbs included bird’s foot violet, compass plant and two other species of Silphium, culver’s root, various asters, goldenrods, sunflowers, and legumes.

Indian grass, one of the dominant tall grasses in mesic prairie. Photo copyright 2009 Richard Brewer

What happened to it?–Mesic prairie was the first land settled and nearly all was plowed.  The only parcels that escaped were in the earliest cemeteries and perhaps some land along the earliest railroads.  However, some remnants of bur oak plains and white oak openings on better soils included plants that also were prominent on mesic prairie. In the past 30 or 40 years, disturbance and lack of fire have reduced or obliterated the few remnants in these categories.

Current status–All sites containing any combination of mesic prairie species are worthy of preservation; however, most sites dominated by mesic prairie species will be the result of restoration.

4. Bur Oak Plains (3% of Township)
This savanna was usually adjacent to mesic prairie.  It shared many of the same herbs and grasses and probably originated (and was eliminated) in the same way.  No remnants that include bur oaks and characteristic ground layer vegetation are known.

5. Beech-sugar maple Forest (6.5% of Township)
Trees–Beech, sugar maple, basswood, tulip tree, white ash, slippery elm (now nearly gone from Dutch elm disease), red oak, bitternut hickory.

In understory–Blue beech, hophornbeam.  Spice bush and red-berried elder are the most important large shrubs; running strawberry bush (genus Euonymus) and gooseberry also occur.

Herbs–A large variety including the spring ephemerals such as spring beauty, toothwort, large-flowered trillium, Dutchman’s breeches.  Non-ephemerals and summer-flowering species fewer; examples are nettles, putty-root, water-leafs, wild leek, May-apple, blue cohosh, doll’s-eyes.

What happened to it?–Mostly cut over and converted to agriculture.  Beech-maple forest in Oshtemo was the south end of the same patch that extended northeast all the way to Cooper Township, where relict stands persist in Markin Glen Park and the Kalamazoo Nature Center.

Current status–Virtually gone.  Elsewhere in Kalamazoo county, a few remnants were preserved by land owners because of their beauty and the spring flowers; some of these have been permanently protected.  If any patch of even five or ten acres still existed in Oshtemo Township, it should be conserved. In many preserved sites, the invasive garlic mustard is a serious threat to the herb layer.

6. Wetlands (0.5 present of township)

Small amounts of swamp forest and marsh were evident from the original land survey.  A few kettles with perched water tables held buttonbush swamps. As far as now known, no bog, tamarack forest, fen, or other specialized types of wetlands occurred.  Likewise, no floodplain forest was present.

Current status–If any of the seemingly absent types such as fen, bog, or wet prairie were found in the township, the sites would be worth conserving.  Perhaps the small wedge of swamp forest in the northwest corner should be considered for protection.

[Added 15 November 2009. Over the past week or two I noticed a tamarack tree in the wetland at the west edge of the Lilian Anderson Arboretum not far south of West Main (M-43) in Section 15.  In the fall, tamarack needles turn a gold color, so a tamarack is easily noticed at this time.  I finally stopped by yesterday, by which time many of the leaves had fallen and the few remaining ones were dull brown.  The situation where the tamarack is growing is consistent with the possibility of fen, though I have not noticed fen species at other places along the edge of the wetland on many other trips to the Arboretum.  The site is at the base of a slope where ground water feeds a sizable wetland northeast of Bonnie Castle Lake.  There are more wetlands across M-43 to the north.  I tried to walk around in the vicinity of the tamarack without sinking too deep, and I didn't see any obvious fen indicator species.  But it's not a good time of year.  I'll have another look or two next spring and summer.]

Conservation Overview

Little natural land is currently preserved in Oshtemo Township.  The two township parks are mostly devoted to active recreation.  A few years ago the Township lost an opportunity to create a contiguous protected area of at least 200 acres when it voted to convert most of the larger park (Oshtemo Township Park on West Main Street behind the township hall and the library) into an 18-hole disc golf course. A color map available at the township website gives a clear picture of how much of the park was removed from natural processes and devoted to disc golf.

Adjoining the Oshtemo Township disk golf park on the west is more than 130 acres of conserved land owned by Kalamazoo College.  The Kalamazoo College land has been dedicated as the Lillian Anderson Arboretum; however, only about 30 acres of the land is, in fact, permanently protected (by a conservation easement held by the Southwest Michigan Land Conservancy).

Another protected tract is a short segment of the Kal-Haven Trail (owned by the state of Michigan) cutting across the northeast corner of the township.  Adjoining this section of the Kal-Haven Trail is about 100 acres owned by the Kalamazoo Nature Center as the result of a bequest from Mildred Harris.

A part of Western Michigan University’s Asylum Lake property lies in Oshtemo Township between Drake Road and U.S.-131 .  It is, to a degree, protected since it was conveyed to WMU by the state to be used “solely for public park, recreation or other open-space purposes unless otherwise authorized by public act.”  Part of the 55-acre site was used as an orchard by the Kalamazoo State Hospital’s Colony Farm from the 1880s into the 1950s.  The now-abandoned orchard supports a number of forest and thicket bird species. The land is also of historical and archaeological interest because of its use in the farm operations of the state hospital and also because of its location within the savanna complex immediately surrounding Genesee Prairie.  See the next (earlier) post for a current threat to the continued existence of this protected land.

Few other protected sites exist.  Most of the land holdings in the township are small parcels of 40 acres or less. Consequently, establishment of preserves large enough to be suitable habitat for birds and larger mammals will in most cases require acquisition (or protection by conservation easement) of two to several parcels.

This is a short version of a talk I gave at the Oshtemo Historical Society, Kalamazoo County, Michigan, this spring (March 2009) on the original vegetation of the township.

I’m using 1830 as the beginning date. There are good reasons for choosing that year. One of Kalamazoo County’s famous early settlers, Benjamin Drake, arrived with his wife, Maria, on Grand Prairie in 1830. The family settled in the Oshtemo part of the prairie (which extended across the line into Kalamazoo Township). Enoch and Deborah Harris, the county’s first black settlers, arrived about the same time, maybe a little earlier, on Genesee Prairie in the southern part of Oshtemo Township. For the settlers, the tall-grass (mesic) prairies were destinations, like islands in the ocean.

Also,1830 was the year that the General Land Office Survey for Oshtemo Township was conducted. The survey produced data that allows us to form a pretty good idea of what the vegetation was like at the time. The survey and settlement are connected, of course, because the purpose of the survey was to establish the sections,townships, and ranges that provided the framework for the sales of land to the immigrants.

Even though the purpose of the survey was not botanical, it collected information as to species and diameters of trees at section corners and quarter sections, along with their distances from these points, allowing a relatively accurate reconstruction of the vegetation. Using this data and other sorts of information from the original land survey along with topographic information, a map of the vegetation of Kalamazoo County in 1830 was prepared (T. W. Hodler, Richard Brewer, L. G. Brewer, and H. A. Raup. 1981. Pre-settlement vegetation of Kalamazoo County, Michigan [map]. WMU Geography Department, Kalamazoo.

Of course, Oshtemo history doesn’t start at 1830. We know that LaSalle with a band of four men went through southern Michigan in 1680, and it’s likely that his route went through Oshtemo, probably right through Grand Prairie. It was about this time of year, probably the last week of March.

But the Potawatomi were already here, having arrived about 1700 from Wisconsin. As far as vegetation and animals go, Oshtemo history starts around 14,000 years ago when Pleistocene glacial ice disappeared from Oshtemo and adjacent areas to the south and east. Paleo-Indians followed the mammoths and other now-extinct large mammals into an open grassy, sedgy landscape that also contained a few species of plants related to today’s tundra.

If we compare Oshtemo Township with the rest of Kalamazoo County, Oshtemo was one of the less diverse townships vegetationally. Most of the land was occupied by the related communities of oak savanna, oak forest, and prairie. Here are the percentages of the total land area and the geological land form each community occupied :
Oak savanna                                 61%      Outwash, moraine
Oak forest                                     27 %      Moraine
Bur oak opening                            3%      Outwash, moraine
Mesic Prairie                                  2%       Outwash
Beech-sugar maple forest         6.5%    Moraine
Marsh and other wetlands        0.5%   Moraine

Several other plant communities, especially wetlands like bogs, fens, and tamarack swamps, were almost absent from Oshtemo.

What is the explanation for this pattern? A major reason is that most of the township consists of high lands often with sandy soils, formed by the Kalamazoo moraine and associated outwash plains. Oshtemo seems to be a made-up Indian name. Henry R. Schoolcraft, the 19th century geologist and ethnologist, evidently derived it from a couple of Ojibwa words that mean, more or less, head-waters (Virgil J. Vogel, 1986. Indian Names in Michigan. The University of Michigan Press, Ann Arbor. ISBN 0-472-10069-6). It’s unlikely the Potawatomi of Grand or Genesee prairie ever described themselves as being from Oshtemo.

Wherever the word came from, it describes the Oshtemo topography pretty well. It’s high ground with few lakes and no named rivers. Some water runs off above ground a little way, but most soaks into the sandy soils and is carried away underground in various directions eventually ending up either in the Paw Paw River or the Kalamazoo River.

A second major factor, working in conjunction with topography and soil, was fire.  Most fires in this region were probably Indian set.

Oak savanna was the predominant plant community of the township. Savanna refers to wide-spaced trees in a landscape that otherwise has grasses and herbs. As an arbitrary dividing line between forest and savanna, the Kalamazoo County map of original vegetation used 50% canopy cover. That is, if we measured at solar noon, the shadows of the tree crowns on the ground would cover about 50%.

Kim Chapman, a former student, and I wrote a long article on the savannas and prairies of Michigan that appeared in the Michigan Botanist (K. A. Chapman and Richard Brewer. 2008. Prairie and savanna in southern lower Michigan: History, classification, ecology. Michigan Botanist 47(1): 1-48. We see the savannas, prairies, and oak forest as going together to form a dynamic system in time and also space. For example, we see any one patch of land switching from forest toward savanna, or savanna toward prairie during dry and warm periods when fires were frequent . With decreased fire frequencies during moister or cooler periods and also following settlement, the system would shift the other way. The savanna vegetation was patchy because of differences in elevation, soil moisture, and slope exposure.  The patchiness was probably least in extensive flat areas.

The next post will give a few more details about the original plant communities.
