WHAT’S GOING ON IN THE FOREST
Sometimes this tree can be confused–when the leaves fall off–with oak; Its bark is similar when it reaches old age. But it’s really big-tooth aspen or as some might call it, “poplar.” If you see it growing in a mature forest, it can be difficult to visualize, but that forest was most likely cleared once upon a time, and a long time ago. Aspen is extremely shade-intolerant and its presence normally indicates land clearing for agriculture or intense forest burning. This tree was found amongst mature hemlock, sugar maple, and black birch–all trees that are shade-tolerant. Aspen most likely predates all of these newcomers and “pioneered” the newly growing forest after mass disturbance. While it’s the first tree to grow back, it is usually the first to die due to shade.
