Fall Color Conspiracy
Conspiracy hypotheses (or theories, as we like to call them, since “hypotheses” cannot be uttered without a lisp) seem to multiply unfettered these days, so I feel awkward birthing yet another. But you may be intrigued to learn that the wide spectrum of color in the region’s fall foliage is largely the result of a Depression-era project implemented by the Hoover Administration.
We live in one of the few places on Earth where trees produce such a…Continue

Obviously, we need another word, because these two things – whispering pines and rustling leaves – may both soothe us, but they sound quite different.
In our little home in the…Continue

As someone whose job it is to help preserve trees, I find it ironic that in nearly every case I am saving them from us. We injure their root systems, whack them with mowers and weed-eaters, plant them too deeply, and do many other things which jeopardize their health. It would be terrifying if they could fight back in the manner of Tolkien’s magical Fangorn Forest. For one thing, tree work would be a lot more dangerous than…Continue
Maples on the Move
Unless trees are wondrously furtive, I’m pretty sure they don’t travel. But their species ranges can. A report from the US Forest Service’s Northern Research Station indicates that due to climate change, 70% of Eastern tree species have already begun to shift their ranges to the north. The authors admit this is not a new trend, but rather the hastening of an old one:
“Tree ranges in ancient times certainly shifted according to changing climates, but the…Continue
