Firewood.
We took out two leaning black cherries. A third cherry was left, because black cherries, while tiny, are quite tasty. Spit the pits out! Cherry pits contain amygdalin.
We took out a half dozen small scruffy elm trees and mulberry trees. Two large red mulberry trees were left to anchor the southern edge of the forest, because mulberries are also quite tasty.
We took out a box elder, nearing the end of its life. All of the trees we cut were about 40 years old, and one was quite hollow in the middle. Check out the mouse cache of bittersweet berries.
We also removed a variety of impenetrable bittersweet vines, green briar vines, honeysuckle bushes, and blackberry canes. The blackberry canes will come back with a vengeance (as will, regrettably, the others), but we needed a clear space to work in. Underneath that mess, we discovered the old fenceline.
The firewood will be split, allowed to dry for two years, and then used to boil maple sap into maple syrup. It will also be used to heat the pizza oven.
