Autumn among the beeches
If life is getting you down or you’re feeling particularly stressed why not take a gentle afternoon stroll through a beech wood? Walking through a beech wood in the fall is a serene experience that will instantly melt away your troubles. And if you look closely, the beeches have a few surprises in store…..
The American Beech (Fagus grandifolia) is a fairly common tree across almost all of the eastern United States and is easily recognized by its smooth, pale gray bark and its above-ground ‘knees’ formed by the tops of its shallow roots. We have several stands of old, large beech trees around our DNS sites because early settlers tended to leave them alone as they often grow on hillsides which aren’t attractive sites for home building or farming, and also because their hard wood is difficult to cut.
At this time of year the ground beneath a beech wood is littered with a carpet of their golden leaves and if you wait long enough you will see a variety of mammals and birds rustling though them in search of fallen beech nuts. These distinctive triangular nuts emerge in pairs from their tough, furry husks when ripe and are beloved by deer, squirrels and Blue Jays and were apparently the favored food of the extinct Passenger Pigeon. Beech nuts are edible to humans once they have been peeled although they are apparently bitter and may even be toxic in large quantities so we do not recommend that you eat them.
Part of the reason beech woods are so attractive to walk through is that they are remarkably open, with very little understory of bushes or shrubs to navigate through. This is because beech trees are thought to be allelopathic, meaning they exude a chemical into the soil around them which inhibits the growth of other plants. Sometimes the only plant you see growing near a beech tree is a ring of ‘root sprouts’ growing around its trunk, which is a direct way through which beech trees spread in addition to their nuts.
Still, despite their placid outward appearance beech woods are tinged with intrigue. If you get down on your hands and knees you will notice that most of the trees have a circle of mysterious brown weedy stems around their base. These are known as Beechdrops (Epifagus virginiana) and are among a handful of plants that don’t photosynthesize but instead live parasitically by burrowing into the roots of beech trees and extracting their nutrients.
So please take the time to explore a beech wood this fall, but be sure to appreciate the small struggles going on underneath these giant trees!
