Abstract
Hemlock-beech forests once covered 6 million acres of the Allegheny Plateau in Pennsylvania and New York. To preserve a remnant of this forest, the Federal Government purchased the last remaining uncut hemlock-beech forest in 1936. Four years later, half of this area was set aside in the Tionesta Scenic Area, primarily for public enjoyment; the other half was set aside in the Tionesta Research Natural Area for scientific study. Both areas are administered by the Forest Service, U.S. Department of Agriculture. A brief ecological history of the area shows the changes that have occurred in the forest. Strong winds resulting in extensive areas of blowdown have led to the regeneration of intolerant species and the development of second-growth stands in a climax forest. Deer browsing has virtually eliminated hobblebrush from the understory and limits regeneration to unpalatable species such as beech. Lists of trees, shrubs, herbs, and vertebrates present in the early 1930s are included.
