Stands of forest trees of either seral or climax species growing singly or in association with other tree species. The stands are usually well past the age of maturity as defined by the culmination of mean annual increment and often exhibit characteristics of decadence. These characteristics may include, but are not limited to: low growth rates, dead and dying trees, snags, and down woody material. The stands are usually characterized by large diameter trees relative to species and site potential, multi-layered canopies, a range in tree diameter sizes, and the presence of understory vegetation. The specific attributes of an old-growth stand are primarily dependent on plant associations and forest cover type.
