Tuesday afternoons in the woods

by Sandy Garland

When our ash trees were taken down last spring, not only did they leave enormous “holes” in the Old Woodlot, but they also caused damage to other trees and plants when they fell and were dragged out of the area. Increased light means the ground vegetation is likely to change. All this prompted us to form a regular work group to restore this habitat and create a mixed woodlot full of a variety of native plants, shrubs, and trees.

A small group of us have been tackling this work, a bit at a time. Here are some successes and some things we’ve seen.

Over the last few weeks, a priority has been to remove Garlic Mustard, especially plants that are blooming as we want to prevent any more seeds from planting themselves. Garlic Mustard is an invasive species that is especially a problem in woods. See our fact sheet and photos.

Dog-strangling vine (DSV) is the most difficult invasive species to control. In fact, we don’t seem to be able to control it at all. Our goal is to at least keep the plants that are already in the woods from producing seeds. Mirko proved to be very adept with a scythe last Tuesday and cut a lot of DSV that was just starting to bloom. We’ll have to cut these same plants again in a month and probably once more in late summer as they grow back quickly. But if we can deplete the resources the plant stores in its roots, we might gain a few “points” in the battle. See our fact sheet and photos.

Kate chose to dig up DSV as that’s the only way to truly get rid of it. We dig it out around “good plants,” but it would take an army to do this all through the garden. In this area, goldenrods, blackberries, native clematis, and other wildflowers are competing with DSV. We’re on their side. While working, Kate found this gartersnake that seems to live on the south edge of the woods.

Another way to fight DSV is to cover thick patches of it with a tarpaulin. The tarp has to be left in place for more than a year to make sure the plant roots are killed. Last week, Catrina and I moved a tarp from this area to an adjacent one. I was very pleased to see that blackberries from nearby had grown runners under the tarp and were now sending up new shoots. You can just see blackberry flowers at the right of this photo. And you can just see the tarp in its new location in the background.

Names of plants

In addition to invasive species, we’re all learning the names of the “good” plants. At the left are Large-leaved Asters (Eurybia macrophylla; see our database), a good ground cover in shady areas. They DO bloom, in late summer and early fall, usually just before Heart-leaved Asters.

At the left are two spring ephemerals, both of which have three-part leaves: Jack-in-the-Pulpit (Arisaema triphyllum; database) and White Trillium (Trillium grandiflorum; database).

Interesting sightings

We learned that Kate’s the one with sharp eyes – and a great cell-phone camera. She spotted and photographed a huge spider (not sure what species), a morel mushroom growing in our plant nursery, and a colourful American Toad (Anaxyrus americanus).
