Old Growth (1) Forests that either have never been cut or have not been cut for many decades. (2) Forests characterized by a large percentage of mature trees. (3) A late stage of forest succession. Although the specific characteristics of old-growth stands vary with species composition and history, some commonly expected attributes in mesic forests on productive sites include: an abundance of large trees at least 180 to 200 years old, a multi-layered, multi-species canopy dominated by large overstory trees with moderate to high closure, numerous trees with broken tops, snags, and large logs.
