A Problem Solved: WMU’s BTR Park Downtown on Arcadia Commons

 

The following was submitted to the Kalamazoo Gazette on 8 June. The next day the Gazette’s Community Engagement Specialist informed me that it would be published as a guest column within the next few days.  This has not happened as of 15 June so I decided to post it here in a slightly expanded version.

Solutions may not show up until long after a problem arises. For example, smallpox appeared as a new disease in humans thousands of years ago, but vaccination wasn’t invented till 1796.

A quicker match has appeared for one of Western Michigan University’s problems. WMU needs a substitute site on which to build a new BTR park. Currently, the school plans to use the Colony Farm Orchard, a largely natural wooded site adjacent to Asylum Lake Preserve.
The group Save the Colony Farm Orchard has suggested that this development is a bad idea because–among other problems– it would destroy the historic orchard with its varied flora and fauna, would have a harmful influence on Asylum Lake Preserve, and would intensify the already-unpleasant urban sprawl of this region where Kalamazoo and Oshtemo Township meet.

More than a few people have pointed out that brownfields or other vacant lands in downtown Kalamazoo avoid all these problems and are the logical place for WMU’s new BRT park.

And now comes the Gazette for 4 June 2015 with its front page headline
“Developers sought for Arcadia Commons.”

The story begins, “A task force is looking for someone to help it decide what to do with the undeveloped Arcadia Commons property in downtown Kalamazoo.” It goes on to describe the four-block property bordered by Kalamazoo Ave, Park St, Water St, and Westnedge Ave. The site is slightly more than 6 acres, and WMU already owns half of it.

This is one of those rare situations in which two individual problems: (1) Where should WMU’s BTR park go? and (2) What is a viable use for the area northwest of Kalamazoo’s central business district? each forms the solution to the other.

Clearly, the stars have aligned to tell us that WMU’s BTR park should go on the Arcadia Commons land.

Land that once, a few years ago, was being considered as a place to house some combination hockey arena/assembly hall we now see is meant to hold the second stage of WMU’s BTR park.

Possibly the rich assortment of medical resources downtown, including WMU’s new medical school, is pointing to the area of emphasis for the new BTR park.

Tuesday Noon (26 May 2015) Nature and Art at KIA

A program coming up at noon Tuesday (26 May) at the Kalamazoo Institute of Art sounds promising for people interested in art and nature. Here’s what the KIA’s website says about it:

 

From the Darkness: Light: What an Ecologist and a Poet See in the Art of Ladislav Hanka 

Presenters: James Armstrong, Kim Chapman and Ladislav Hanka

Ecologist Kim Chapman and poet Jim Armstrong, authors of the upcoming book Nature, Culture, and Two Friends Talking, a collection of essays addressing our complex relationships with the natural world, will present an in-depth look the work of Ladislav Hanka.
Working loosely from their book, the two will engage in a wide-ranging discussion about how Hanka’s work creates a dynamic confrontation between art and science, wildness and civilization, beauty and ugliness, darkness and light. As a special feature of this talk, Hanka will be present to join in the conversation.

All three–Kim, Jim, and Lad–have a strong local connection, to Kalamazoo and to one or both of our local institutions of higher learning. They also all have strong conservation credentials and are skilled writers with distinctive voices.

Lad–Vladislav R.–Hanka is a resident of Kalamazoo, well known as an artist, especially as a print-maker. He recently published a remarkable book In Pursuit of Birds, A foray with field glasses and sketchbook, Drawings and etchings of birds with some stories of birding in exotic places. Among his other activities, he has been a recent critic of Western Michigan University’s development plans for the Colony Farm Orchard (as he was also in 2009-10).

Kim Chapman studied the native grasslands of Michigan while at W.M.U and later did a Ph.D. in conservation biology at the University of Wisconsin. He spent several years saving land with The Nature Conservancy chapter in Minnesota.  Currently, he lives in St. Paul and directs an ecological consulting firm.

Jim Armstrong earned a Ph.D. at Boston U. in American literature. and is on the faculty of the English Department at Winona State University in Minnesota While in Kalamazoo, he wrote a series of articles for the Gazette that dealt with local land conservation. The series contributed to the  current that led to the formation of the Southwest Michigan Land Conservancy.

From the KIA description, it sounds as though Kim and Jim are going to talk about some of the themes in Lad’s new book, but we’ll have to wait and see.

Kim and Jim have collaborated before, notably on a critique of the Little House on the Prairie series of books by Laura Ingalls Wilder. Their approach was ecological; the title was What Laura Saw: Making a Little Home on the Extreme Great Plains. I talked a little about their paper (which had been presented at an environmental conference at WMU) in a post to this website on 10 February 2011.

The Tuesday program is in the KIA’s ARTBreak series. Bring your brownbag lunch; coffee will be provided.  Free parking in the KIA lots.

Earth Day 2015 Colony Farm Orchard Protest

The Save the Colony Farm Orchard group held a second protest rally at the Orchard on this day (22 April 2015). Three speakers made brief remarks. The following is approximately what I said plus a few things that I left out for brevity or that I should have said but didn’t.

My topic was What would be the ecological effects if Western Michigan University develops the CFO as it proposes and turns it into another BTR park?

A quick answer is that everything currently there would be obliterated.

What in particular would be lost? Two things: the history of the land and the natural history of the land.

The CFO is land that was once part of a tall-grass prairie, the Genesee Prairie, surrounded by a bur oak savanna. The CFO was probably mostly in the savanna.   In the 1800s what’s now the CFO was part of private farms that included orchards.  Later it was the orchard part of the Colony Farm of the state mental hospital. The Colony Farm ceased its agricultural operations beginning in the 1950s and the CFO was all but abandoned by about 1970.

The CFO as it stands could provide information, in the plants and in the ground, of the history of the site from Paleo-Indian times to settlement, on through the 20 century. Mark Hoffman, the historian of the Colony Farm, can tell us that Neil Hindes had an orchard in the area, consisting of 100 apple trees plus others, in 1844.

Apple trees are long-lived.  Could  the apple trees there today be the same ones?

Will we find out the age of these trees when we count tree-rings on the stumps after WMU cuts them down?– Just before the bull-dozers move in?

Of many specifically ecological effects, I’ll mention three.

(1)The first is speeding up return of the sequestered carbon of the site to the earth’s atmosphere as carbon dioxide. Included will be the carbon in the living and dead trees–many quite large–in all the rest of the living vegetation including a very dense understory, and in the thick, long-undisturbed soil–the leaf litter, the humus. The stored carbon will go into the atmosphere and contribute to global climate change. Of course, in the global scheme of things, the carbon from only 40 or 50 acres is small. Somebody should calculate how many more LEED certified buildings WMU would have to build to save enough energy to achieve a balance.

(2)The second is the loss of the plant-animal community of the CFO. The CFO is an odd, interesting site. It has gone nearly 50 years with minimal direct human influence (except for the devastated southern end where the electrical substation was put in in 2001).
The CFO is a site of surprisingly high diversity, both as to species number and also in patchiness. There are patches dominated by native plant species (such as bur oaks and other species of the primeval prairie and savanna. Other patches are dominated by non-natives, including some considered invasives. There are lots of species of plants that flower at different times making it good habitat for honey bees–and probably also native, solitary bees.

Much of the CFO land has a thick understory–head-high and taller–making it excellent cover for many smaller mammals and ground-inhabiting birds.

The thick understory also makes it slow walking for people. This is not a park; visitors have to zig-zag their way along, following the route of least resistance.

Animal species diversity here is high too, partly based on the small human presence and partly based on vegetational diversity.  A morning bird walk here in most seasons would probably produce as many or more bird species as a walk of the same length through the woods on Asylum Lake Preserve.

(3)The third effect and probably the one of greatest ecological consequence, is the effect on Asylum Lake Preserve. Loss of the CFO is another step in the ecological pauperization of the supposedly protected Asylum Lake Preserve. The CFO  is, functionally, 54 acres of complementary habitat added to the scant 274 acres of the preserve. Coyotes, red foxes, and deer slip back and forth between the Asylum Lake Preserve and CFO. Many bird species, including ground-nesters such as as American woodcock and wild turkeys can nest here, probably including ones that forage on the Asylum Lake Preserve. And there are many other connections.

It’s a well-established conservation principle that bigger is always better where preserves are concerned. One important reason is that the rate of local extinction of species is lower in bigger preserves. With a lower extinction rate, species diversity tends to be higher, and higher species diversity usually is accompanied by greater ecological stability.

Besides these connections, the CFO serves as at least a partial buffer for the noise, fumes, lights, and so forth coming from what’s in and around Stadium Drive, 131, and 12th Street. Even a little BTR Park like the CFO would  yield will, with its roads and parking lots and business operations, bring noise, lights, and chemical emissions just across the road from the Asylum Lake Preserve.

The WMU administration has reminded us repeatedly that they have
no intention to harm Asylum Lake Preserve. Where I come from, making a big deal of  the fact that you’re promising to do what you’re legally required to do would prompt sarcastic comments.

But the claim is a sign of a serious problem. WMU administrators apparently think that only direct assaults on a site can harm it. That the structure and functioning of Asylum Lake Preserve would be damaged by interfering with the Colony Farm Orchard seems to be beyond their ken.   We’ve listed a few of the connections between the plant and animal populations of the two sites, and the list goes on. Connections are what ecology is.

 

 

Spring Wildflower Walk at Brewer Woods

 

Under the auspices of the Southwest Chapter of the Michigan Botanical Club, I will lead a field trip at the Michigan Nature Association’s Brewer Woods Sanctuary on Saturday 2 May 2015. It begins at 10:00 AM at the woods, located in Pavilion Township.

The 41-acre preserve is mostly beech-maple forest, or southern mesic forest. On the west edge it grades into slightly wetter forest, including some vernal pools. It has a remarkably rich display of spring-flowering herbs. I’ve written about in often in posts of earlier years.

Here are the directions for getting there, as provided by the Botanical Club:

Please  car pool at the I-94, Oakland Drive Park-and-Ride, and to leave there no later than 9:15 A. M. From there drive East on I-94 and exit South on Portage Road. Turn left ( East ) on Bishop Road. Drive East about 3.9 miles ( thru Sprinkle road, continue East, then Southeast, then East again) Bishop road becomes East P-Avenue, then East P.Q.-Avenue). At the T-intersection with 29th Street, turn Right ( South), about 1.5 miles to East R-Avenue. Turn Left ( East) about 0.7 miles to 8297 East R-Avenue ( the entrance to Brewers Woods preserve). At the driveway turn left ( North) about 1/4 mile to the house and garage. Someone will be there to guide you as to where to park.

I would only add that car-pooling is essential. Space for parking within the sanctuary is very limited, and no parking is available on the driveway or on the street (R Ave.).

Early May should be a good date for a spring wildflower walk this year. The season so far is quite late. A friend and I visited Harris Sanctuary just about a week ago (6 April) and in a quick walk around found almost nothing above ground as yet.

We did see the leaf tips of a couple of wild garlic clumps and a very few just-emerging plants of toothwort, Dentaria laciniata (which, as my friend noted, is now given the name Cardamine concatenata). We also saw a few widely scattered,very small plants of cleavers, Galium aparine.

So it’s a late season, presumably related to the cold and snow-covered  February and March.

We do have bloodroot, Sanguinaria canadensis, in bloom here in Oshtemo Township as of today (12 April) The bloodroots were transplanted; they are growing well enough here among the oaks but probably were rare or non-existent in this habitat in pre-settlement times.

There is a patch or two of bloodroot at our field trip destination in Pavilion Township, but they were transplanted there too. However, their source was Myrtle Powers’ place just north of Scotts, only a few miles to the east of Brewer Woods. Myrtle was in the Biology Department at Western Michigan University when I arrived.

Katy pointed out the bloodroot flowers to me and mentioned that she had seen leaves of hepatica above ground–no flowers. But, spring is coming. and by May 2 there may be a good representation of early, middle, and late spring flowers.

The bloodroots in Pavilion probably won’t still be in bloom. The flowering period of bloodroot is very short. But the single leaf each plant has will still be there, as will fruiting stalks with the capsules that are a good indication of bloodroot’s membership in the poppy family.

Today (13 April) around noon I noticed that the bloodroot flowers were still closed from their usual night-time closure. It’s a cloudy, dark, rainy day.

The night-time closing behavior of plants has the technical name nyctinasty. Just so you know.

Another sign of spring, the shadbush in our yard (Amelanchier) as of this morning has swollen flower buds.

Two last notes on the bloodroot. The sun came out and by late afternoon, the flowers were fully open, but by the time I got back from a meeting, around 7:30 PM, with the sun still shining but low in the sky, the flowers were nearly closed again.

See you at Brewer Woods Saturday, May 2.

Must the Colony Farm Orchard Be Developed?

 

Between 1959 and 1977, Western Michigan University (WMU) received gifts of  land–the Colony Farm–that had been acquired by the state with tax-payer money several decades earlier. The land came to WMU with a restriction that it was to be kept as open space for public use. The gift and the restriction were mostly the work of two Kalamazoo brothers, Jack and Bob Welborn, who were serving in the state legislature.

In 2009, at the instigation of WMU, claiming that it would soon need to enlarge its BTR Park (Business Technology Research), the Michigan legislature passed, and the governor signed, a bill removing the open space/public use restriction on one parcel of the land, the Colony Farm Orchard. This happened following a long battle that involved an unprecedented outpouring of grass-roots opposition to the action, in the media, at local gatherings, and in letters, phone calls and personal visits to legislators in Lansing.

Now, about 5 years later, WMU is trying to move forward with the invasion, and destruction, of the Colony Farm Orchard for a BTR park expansion, as threatened in 2009.

Some local residents, remembering the long battle and the loss in Lansing, resulting in the removal of the open-space covenant, have concluded that the land must now be developed.

This is not the case. Even though the restriction is gone, WMU is not compelled to expand the BTR park onto this land. The Orchard land is still perfectly available for permanent protection.

It is a fact that the original language of the bill that WMU gave to Kalamazoo Representative Bob Jones to carry to Lansing called not just for removing the open-space restriction, but also for replacing it with a new one. The new one would have required that the land be used exclusively for expanding and improving the BTR Park.

But not even the 2009 Michigan legislature would buy that.

The finished version of the bill had only one restriction–that any “aboriginal antiquities” found on the site belonged to the State.

So, the open space restriction is gone. As far as the law is concerned, WMU can now do whatever it likes with the land. This means that the life of Colony Farm Orchard is in the hands of President John Dunn and the eight members of the WMU Board. Thumbs up or thumbs down.

The president and the board at most universities have a lot of power over property, programs, and positions. Mostly, it seems to me, universities behave pretty decently and not as arbitrarily as they could behave.

One reason is respect for their constituencies–alumni, current and future students, local citizens, faculty–present, past, and potential– patrons of concerts, sports fans, donors of many sorts, and so on down the list of people who are watching and forming opinions.

But I suppose universities may also listen to other constituencies , ones whose interests run more to corporate, mercantile, commercial and political matters, tax-sharing and such, and not so much to  things like science, history, or art.

Will the Colony Farm Orchard be developed? The answer depends directly on the president and the board.

It could also be said that the answer depends on who of its constituents WMU chooses to listen to.

 

Petition to Save the Colony Farm Orchard is Available to Sign

Western Michigan University has once again renewed its attempt to demolish the naturally occurring vegetation and fauna of the Colony Farm Orchard (CFO). The purpose, it is claimed, is to expand WMU’s Business, Technology, Research (BTR) Park.

 

Many of us will remember the battle between WMU and the pro-environment opponents that occurred in 2009-2010.  For anyone who doesn’t remember, this website has a few dozen posts from 15 July 2009 to 23 July 2010 concerning that battle.  It was too complicated to summarize quickly, though I may take a shot at it in a later post.

 

The object of this post is to point out for those of us who would prefer that the CFO remain as natural open space rather than be turned to some unknown BTR-type use, a petition to that effect has been started by a bunch of WMU students, a few faculty (mostly retired as far as I know), and assorted local residents.

 

The petition asks that WMU live by the original restriction and consider the Colony Farm Orchard a part of the Asylum Lake Preserve.  It also asks that Oshtemo Township and Kalamazoo County refrain from joining WMU’s  plans to develop the land.

But any interested parties will need to read the petition, which can be done here:

The petition was put up for reading and signing sometime Thursday night (26 March 2015).  By 3:45 PM 27 March, 109 people had signed. When I looked in on the website about noon today (30 March), the number was about 450.

The more the better, of course, so check it out soon and sign if you agree with the cause.

February 2015, California and Kalamazoo

Katy and I gave February in Kalamazoo a miss for 2015, as did a few other people we know.  The Polar Vortex of 2014 was what prompted our and others’ decisions. And away to warmer climates was the right direction to take: The vortex was operating this year too.  Here in Kalamazoo, the daily low temperature  was below the long-term average low for the date  for 23 of the 28 days of February.

Unfortunately, we came back a week too early; the first seven days of March also had low temperatures below the long-term averages, culminating in  Friday  7 March when the low was -2 degrees Fahrenheit, to be compared with the long-term average low for that date of 24 degrees.

Snowfall for February 2015 wasn’t so bad, but  at the end of January there was already plenty of snow here in Oshtemo Township from the snows of  November.  In fact, I can still see a fair amount of that same snow as I look out my window today (20 March).  For the first couple of weeks we were back, driving through the parking lots of the big box stores  was like navigating among icebergs.

We spent February in California, in the Bay area, most of the time in Silicon Valley. The temperatures were mostly 50s at night and 60s during the day.  We saw a lot of birds, especially shorebirds and water birds in the Baylands around Palo Alto.  We  also saw a version of the future for a lot of other parts of the US , if we don’t change our ways.

In the next few weeks, I’ll try to write a little about California and also, of course, about what’s going on around here.

For example, I’m supposed to lead a field trip to the Brewer Woods Nature Sanctuary in Pavilion Township on Saturday 25 April to see–among other things–the spring wildflowers.  The SW Chapter of the Michigan Botanical Club  is the sponsor. I’ll say a little more about the field trip closer to the date.

That’s on the pro-environmental side.  On the anti-environmental side, the Colony Farm Orchard is once again threatened by WMU expansion.  The Kalamazoo Gazette is only a shadow of what it once was, but is still the main way most of us have for keeping up with the local atrocities.  The print version as well as the on-line version, Mlive, carried the 18 March story about the Colony Farm Orchard and Western Michigan University’s renewed attack on this  preserved land.

I’ll have a little more to say about Colony Farm Orchard too.

As I finish this short post today, Saturday 21 March, 2015, the sun is shining.  Almost all the snow is gone–not quite, not here in at the east edge of the snow belt.  With a temperature of 49 degrees. I wouldn’t call it warm. But the sandhill cranes have been overhead, flying north, red-winged blackbirds are back, and the flowers of winter aconite and snow drops are ready to open. The future looks bright.  Except for Colony Farm Orchard.

 

Wood Frogs Calling Today

After a cold March–very different from last year–there are a few signs of spring. Today, at the Oshtemo Township oak area I heard a few wood frogs call mid-afternoon.  The day had gotten steadily warmer and it must have been in the high 50s by then. Air temperature.  I didn’t have a thermometer so I’m not sure what the water temperature was.

Looking back, I see that wood frogs first called here last year on 12 March.  Not only that, I led a spring wild flower field trip to Harris Sanctuary on 7 April 2012.  That corresponds to this coming weekend.  I haven’t been to Harris yet this spring, but at the beech-maple forest in Pavilion Township, about the only things up are spring beauty, wild leek, false mermaid weed, and harbinger of spring.  The last is the only thing that was in bloom as of Monday (1 April). It came up a few days earlier, with flowers that looked like white pin-heads.

Here in the oak woods probably no native herbs are yet in bloom, but winter aconite, snow drops, and crocus are, and honey-bees were visiting the crocus in late afternoon with the air temperature at 59 degrees. Few native herbs are visible above ground, but the rosettes of rather heart-shaped leaves of golden ragwort  were green and healthy a little upslope from the same pond where the wood frogs had been calling.

 

Quote 5. William H. Whyte & Kalamazoo’s Own Walden Woods

Title page of Walden by H. D. Thoreau, Heritage Press edition. Photo by Richard Brewer November 2012

The woods and meadows that so attracted [new residents] disappeared as soon as developers got around to building on them, and if the residents wanted to find what other nature features would be next to go, they had only to check the names of the subdivisions being planned. When a developer puts a woods into the name, or a vale, heights, forest, creek, or stream, he is not conserving; he is memorializing.  Subdivisions are named for that which they are about to destroy.

–William H. Whyte

 William Hollingsworth Whyte, called “Holly,” wrote those words in his 1968 book, The Last Landscape (Doubleday & Company).  Whyte was many things–a keen and scientific student of human behavior, a planner and land conservationist, and an excellent writer.  He was the primary architect of the conservation easement, currently the most widely used method of private land conservation.

Whyte may not have been the first person to notice that developments tend to be named after the natural features they damage or obliterate, but I’m pretty sure he was the first prominent conservationist to state it as a rule. Most of us can come up with local examples. If we saw an ad for lots in a new development called the Preserve at Eagle Knoll, we would win more often than we lost if we bet that the knoll had been flattened, the eagles were gone, and nothing was preserved.

Recently, I came across a related but slightly different approach to naming developments right here in Kalamazoo.

A good many years ago, Western Michigan University bought some property a little beyond the west edge of the campus.  The property, sometimes held in the name of the WMU Foundation, adjoined a city well-field and the Arcadia plat and lay between Solon Street on the east and Drake Road on the west.  WMU had bought the land thinking they were going to need a bigger, grander football stadium, but the need didn’t materialize, and it turned out that the cost of such a project, especially the required utilities, was prohibitive.

The land, which for convenience can be referred to as the Arboretum, was mostly recovering agricultural fields but with a few relict patches of native vegetation.  On the northwest side of the property grew a few bur oaks of various sizes.  This was near the south edge of one of the eight tall-grass, black soil prairies of the county–Grand Prairie–and these trees were a heritage of the fringing bur oak plain.

Also on the north boundary but farther east was a small pocket, a little valley, of mesic forest, but an unusual type of mesic forest with few or no beeches or sugar maples, dominated instead by basswood trees.  Part of this little valley was on the WMU property, the rest on the parcel adjacent to the north.

For a good many years the land abided, the plants and animals cycling through the seasons, visited by no one except walkers and joggers, bird-watchers and berry-pickers, and an occasional ecology class.

Several years ago, things began to change.  Someone interested in the sequence and timing could probably work out the details from the Kalamazoo Gazette mlive archives if they wanted to spend the time.  Here’s a place to start.  A quick synopsis is that WMU wanted to monetize their land holdings, and the city of Kalamazoo desperately wanted an east-west street in the region.  Other business and governmental entities were or became involved. The Kalamazoo School system built a new middle school.  The city built a road, which they called a parkway, crossing the property from Drake Road to Solon Street.  I’ve never known just what a parkway is, but a prominent feature of this one is that there is no place to park along it. One result is that access to the arboretum for walkers is pretty much limited to some of the immediate neighbors.

And the land  began to be developed. A couple of months ago, I saw signs for a new condominium development. The literature on it mentions that it will be “set amidst 80 acres of woodlands and rolling  meadows–of which 40 acres will be preserved.” Just how preserved it will be is unclear; so also are who and what it’s preserved for.  The literature goes on with a set of bullet points one of which is “40 acres of private green space.”

The name of the new development:  Walden Woods.

Perhaps I’m jumping to a conclusion, but the name suggests a connection to Henry David  Thoreau, the famous  naturalist, conservationist, and environmentalist. In an earlier post, I quoted a characteristic passage from Thoreau’s journal that also pertains here:

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…. All Walden Wood might have been preserved for our park forever, with Walden [pond] in its midst….

 

In Kalamazoo’s case, the 180+ acres of the Arboretum could have been turned into a city park–badly needed in this area of the city–along with an adjoining nature preserve. Something of this sort is what most of the neighbors and many other Kalamazoo residents wanted.  But, that, of course, is exactly what did not happen.  Instead, we have what we have, which includes Walden Wood in the form of a condo development.

It’s hard not to see this as another sad example of Whyte’s rule.  But perhaps we should try to take a little cheer from the situation. For example, if other developments follow in the arboretum, the names of dozens of other conservationists and conserved natural areas are waiting to serve. With Walden Woods honoring Thoreau, it would be only fair to have a Muir Woods for John Muir.  One of these already exists, but California is a long way from here so probably there would  be no confusion.

Among Teddy Roosevelt’s many conservation achievements, he set aside the first-ever bird sanctuary, Pelican Island.  How about Pelican Arboretum as a general name for the whole site?

 

A Little More About Beech-Maple Forest in Late Summer

Fallen beechnuts. Photographed 20 August 2012 in Pavilion Township by Richard Brewer

In my last post I talked about how bland and uneventful the mesic forest is in late summer and early fall.  I was giving my impression from a good many years of experience with such forests.  But I spent a few hours on three days recently, actually looking at what was happening.  Partly I was hoping to see Triphora trianthophora and partly I wanted to check my memory.

I didn’t find three birds orchid, and not a lot was happening.  Not a lot, but still more than I had remembered.

For one thing, I had forgotten how important the shedding of fruit is at this time of year.  On 13 August, wild black cherry fruits were numerous on the ground, and there were more of them on visits in early and mid September. I have a feeling that birds that want black cherries eat the ripe–or green–fruit on the tree, but perhaps some mammals wanting the dried flesh or the stone wait for the cherries to drop.  That 60-year-old (but still unsurpassed) manual, American Wildlife and Plants, by Alexander C. Martin and two co-authors, suggests that cherries are eaten by red foxes and gray squirrels, but doesn’t comment on when they gather them.

By 20 September, there were lots of  samaras, the small key-like fruits of sugar maple on the ground.  Sugar maples are always the most common saplings in the mesic woods in Michigan.  There may be a rare year when the seed crop is low, but I think seed supply is rarely a limiting stage in the maple’s life cycle.

It’s not noticeable when you’re walking on the soft earth of the forest, but where the maple fruits have fallen on a hard surface, like a concrete walk, they snap when you step on them, like popping bubble-wrap.  Great fun, almost like popping ripe touch-me-nots.

On the 20th of September also, there were many light tan, prickly beechnuts on the ground, and more were coming down.  Some had one or two fruits inside and some were empty, but I had no way of knowing whether the two, sometimes three, fruits had been plucked out on the ground or in the tree or whether all had aborted.

There’s no question about what animals eat beech fruits.  The answer is everything.  Well, not warblers, but wood ducks, grouse, grackles, jays, woodpeckers, bear, squirrels, fox, chipmunk, deer.

I thought there were especially large crops this year from all these trees–cherry, maple, beech.  Whether some of this could be related to the unusual warmth of the summer is impossible to say.  Tree crops do fluctuate, with one very good year rarely being followed by another.

There were other good things to be seen on my visits to the woods. Lots of herbaceous plants and shrubs were bearing ripe fruit–American poke, or pokeweed, had ripe fleshy fruits.  Such things as Polygonum virginianum and Geum canadense had smallish, dry fruit.  The fruits of red-berried elder were long gone, eaten by birds, but there on the stems, two at a node, were large flower buds ready for next spring.

As I’ve claimed before, not much was in bloom, although Geum canadense had a few flowers with two or three white rounded petals still clinging.

Aster lateriflorus. Photographed 20 September 2012 in Pavilion Township MI by Richard Brewer.

But one species was definitely blooming and near its peak.  It wasn’t  three birds, which I didn’t find.  It was a little white aster, sometimes called calico aster.  The scientific name situation in not very satisfactory, but for our purposes we can refer to it as Aster lateriflorus.

It’s not showy, but it was blooming on August 13 and sill blooming on September 20, with no end to its season in sight.
