Beech Tree Interlude
Thursday, February 4, 2010 at 04:05PM The other week I went for a walk in the woods and met Winter in one of her lovelier moods. There was still snow on the ground and it was cold, but not piercing. The air felt fresh and moist and was a pleasure to inhale. It was morning, before 9 o'clock and the sky was pastel blue, pink, and yellow--it glowed from the inside like mother-of-pearl, or an opal. It had that special luminescence that I love and see only in winter.
I walked all the way through the back pasture and up through the woods trail to sit on the porch swing that John put up between two trees. The swing looks out over one of my favorite section of woods, what I call the Beech Tree Forest, even though there aren't really a whole lot of beech trees. I like it there because the forest floor is relatively free of multi-flora rose and some of the trees are large. They create a true canopy and the sunlight filters through, church-like in the summer. There are some young beech trees in the understory and in winter, their silver bark and their creamy yellow leaves still clinging to the branches stand out in graceful relief against the black trunks of the other trees, and, on my particular morning, snow.
Like dogwoods in spring, beech trees in winter always remind me of lace. I guess that's a bit cliched and I should come up with a better metaphor, but it jumps to mind, I can't help it. It has to do with the way their branches grow horizontally, snaking out to capture what light they can under the bigger trees once summer gets underway. The white dogwood blossoms and the pretty yellow beech leaves look like they've been threaded through a tapestry in an almost even line. It's lovely, dainty.
Beeches grow all big and muscular of course, while dogwoods remain demure. I like the mature beeches, too. They remind me of people more than any other tree in the forest. Their bark is smooth, like skin, and it wrinkles like skin around the joints of their branches. Whenever I come across a grove of full grown beeches, I become a little self-conscious, like they're watching me, and perhaps judging. I'm worried I'll get smacked like Dorothy did by the apple trees in the Wizard of Oz.
Research into why beech trees (and oaks) hold onto their dead leaves ( a phenomena called marcescence) until the new growth in spring pushes them off led me to this answer: No one knows. There are guesses, of course. Perhaps it helps them retain water throughout winter (but this doesn't make any sense to me, since trees lose water through the stomata, little pores, on their leaves). Or maybe they are still getting some nutrients from the leaves (which also seems suspect since all the chlorophyll is gone and what's left are the chemical wastes from metabolism). Or maybe it keeps deer from eating the bark since there are dead, crunchy leaves in the way (hmmm...seems to me that would not deter the eating machines I know as deer). The best answer I found was that maybe it doesn't do them any good at all anymore. Maybe it is a remnant from earlier in their evolution, something like an appendix.
I found that answer in a delightful article about the beech tree here by George Ellison. He found a quote by naturalist Donald Culross Peattie that I would have thought came straight out of the 19th century, given the romantic tone of the prose. This is the kind of stuff I eat right up...
“A beech is, in almost any landscape where it appears, the finest tree to be seen ... Far down the aisles of the forest the beech is identifiable by the gleam of its wondrously smooth bark, not furrowed even by extreme old age ... The elegant clear gray of the bark extends from the trunk to the main mighty boughs so that when the tree stands naked in winter it seems to shine through the forest ... As the foliage matures in autumn [its] delicate leaves . . . turn a soft clear yellow. Then is the beech translated. As the sun of Indian summer bathes the great tree, it stands in a profound autumnal calm, enveloped in a golden light that hallows all about it.”
— Donald Culross Peattie, “A Natural History of Trees of Eastern and Central North America” (1950)
Well. So much for lace! Have a great weekend.
