Abstract
The National Forest Management Act, in part, instructs the Forest Service to maintain the diversity of tree species that are present on federal lands before the onset of management. Further, this act directs the Forest Service to preserve and enhance diversity of tree species within each management area so that diversity is equal to or greater than that of an unmanaged forest. In spite of this directive, it is often difficult to know if management activities are enhancing diversity, maintaining the status quo, or diminishing it. Part of the dilemma is due to the dynamic nature of species composition and the lack of long-term data documenting species abundance with respect to both time and management efforts.
