casanea dentata

Previously we’ve written about the consequences of blight and efforts to reintroduce the American chestnut tree with generic engineering but failed to appreciate the devastating magnitude that the loss of a keystone species had for industry and ecosystem until acquainting ourselves with this extensive Sierra Club article, excerpted by Super Punch. Crucial as building and construction material, the westward expanse of Old World settlers would not have been possible with log cabins and later railroad ties made out of the durable, rot-resistant wood, to say nothing of its sheltering branches and bark, the food-chain of fauna it supported or its pharmacological merits. Cutting or coppicing the tree didn’t kill it and rather it re-sprouted and was ready again to be harvested in a couple of decades, leading to the strangest, tortured Promethean twist in this study: as the blight only damaged the surface part of the tree, extensive root systems still exist, an estimated half a billion individuals and every once and a while grow new saplings, though these too succumb to the fungal disease within a few years.
