A Walk In The Woods


Word was the woods were filled with Indian Pipe, Monotropa uniflora, in exuberant quantities, unlike never before. I headed out -on and off the trail. From the trail, I observed a little patch here, a little there. It was only when I went off-trail that I saw how extensive the slopes were covered with the myco-heterotrophic, chlorophyll-free flowering plant. I just discovered this plant for myself last year in Forest Park, so I have little sense of how unusual such a large population is.

But Rex, having been a woodsman all his life, assured me that he has never seen so much Indian Pipe in any of his woods. This patch was right beside his trail, the oak leaves piled high from a recent oak death above the spot.

Rex, who keeps his trails open to his neighbors, excitedly put up a sign identifying the mysterious plant for neighborhood walkers. I was excited to see his sign, I love signs -tell me more.



This is Hogpeanut, Amphicarpaea bracteata, swamping an area of the woods where a few large trees came down and let in some sunlight. I thought it was a weed, possibly invasive. Instead, it's native to eastern woods, edible, fixing nitrogen in the freshly sunlit soil, and probably is invasive to any garden given half the chance.

Indian pipe, caring not for photosynthesis, crops up even under the hogpeanut.

Adjacent, in the clearing, new oaks grow on the fallen.

And asters.

This clearing, towards the western boundary, is wet, causing much of the trees to fall over in storms. This maintains the clearing, allowing the sun lovers to grow.

Upslope and westerly, the woods abruptly ends at a fence line. Here, goldenrod.

Standing at the edge of the woods, looking northwest, we stare into the top edge of the gravel pit -so called because it was actually an active gravel excavation pit in the past. On the slope into the woods, piles of glacially rounded stones, and some chunks of concrete remain from those active days. Now the pit is covered with birch trees, some cedar, a very different plant community than just 100 feet to the east. No water stands in the pit, it seeps straight into the greater area aquifer.

Walking along this trail, on the northern boundary, we enter a valley with sloped sides.

The recent heavy rains unleashed a torrent down the northern slope. It's hard to make out, but a cleft in the slope, center top, is where the torrent ripped through purely black soil, washing this light gray clay onto the valley floor. It swamped everything in its path. Rex says it will kill the trees growing here. The cleft has been growing every year and there is no will to try to slow the water down that pours through here during heavy rains. There is no humus, no undergrowth to slow the moving water. This is a glacial landscape in flux, hills filling basins.

The red dot you may have noticed in the previous photo was a cluster of berries, the fruit of Jack-in-the-pulpit, Arisaema triphyllum.

First they are green.

Then mixed, finishing up red. These seem to be the only plants that grow in the deep shade under the maples.

Rex is always clearing the fallen twigs and timber, making piles he promises one day to burn.

There are about 8 piles now, all taller than me.

The southern exposure, which faces the large wetland, is occupied by an army of Buckthorn, Rhamnus cathartica. Can I make the greatest claim for invasive species management? That is a whole understory of buckthorn is really boring to explore. All green, all the time and nothing else.

I don't remember what these berries were attached to.

The occasional woodland sunflower.

The occasional woodland ladybug.

The occasional marble. I always find marbles when I am gardening.



Glacial Lakes State Park

Last night I had a tornado dream -usually the kind I have when I am deeply bothered by something. The tornado bears down on me, I hold on. This one shook and rattled the concrete building I dreamt myself to be in. I woke up.

Magically, this made me think of last summer's trip to Glacial Lakes State Park in Minnesota's prairie country. I chose this park as my destination because the name of a nearby lake, Minneswaska, was the same name as a lake and state park in the Shawangunks of the New York's Hudson Valley. And the closest town was named Starbuck.

Minnesota is divided between three distinct regions: northern coniferous forest, prairie, and the western most extent of the eastern deciduous forest (called Big Woods in Minnesota). My trip took me on one of several roads that follow an arc of glacial lakes, or kettles, that remain as reminder of the Wisconsin glacial period (so-so Wiki article). I left the Big Woods and entered the prairie. According to the Minnesota DNR, 98% of Big Woods has been converted to farm land, housing and commercial development and 99.9% of Minnesota prairie has been turned for farm land.

When I neared the park, the land turned from farm to grassland. The road turned from asphalt to gravel.




This landscape was rolling, elevated, scattered stones and boulders about, and grass -lots of grass.



After entering the park, the roadway descends toward a kettle lake. The parking area is surrounded by a glade of trees.


I began walking on the trail that circumnavigates the main kettle lake, called Signalness Lake.
I'm impressed with the oak forest and the feeling like this forest is a hidden pocket in the prairie come farmland. It also strikes me how similar this landscape is to my own Long Island experience with its kettles and oaks.




As you walk down the slope toward the lake, you cross this simple footbridge. It crosses a wetland adjacent to the lake. Among the many plants, milkweed -Asclepias syriaca and what looks like yarrow, Achillea millefolium (native or not???).


I couldn't ID so many of the plants I discovered on this trip, like this one below. It was just above the wetland.




Lakeside, half-way around and looking at my starting location.




Leaving the lakeside I move back uphill toward the drier forest. To the east rolling hills and prairie grassland. Notice how the woodlands are in the depressions in the land, where there is more moisture and protection.



The drier uplands are primarily prairie land. But native sumacs can aggressively fill the slopes without fire as a control agent. Prairie loves fire because it keeps woody plants from taking hold.



Scanning the prairie you see a fabric of grass and other plants.



Closer looking finds brilliant flowers. What is it?




Of course the native coneflower, Echinacea angustifolia.




Hoary Vervain, Verbena stricta




Name this grass.





I know this one because of my time in New Mexico -its Leadplant, Amorpha canescens.



I always enjoy the interpretive signs, especially old disintegrating ones like this explaining how this landscape was formed.
