Hemlock saplings growing amid old-growth trees, Bald Eagle State Forest, Clinton County, on Riansares Mountain. Old-growth forests are characterized by a mix of tree ages and sizes. When a large tree falls, the break in the canopy allows light to reach the formerly shaded forest floor. Tree seedlings, responding to the light, will readily grow. On Riansares Mountain, the rich subcanopy layer of seedlings and saplings indicates that the old-growth forest here is healthy and self-perpetuating. The future of the forest is, however, uncertain; I found hemlock woolly adelgid on some trees at the mountain summit, and the infestation will likely spread.
