In many areas of the Allegheny Plateau, natural forest regeneration fails to occur after harvest cuttings. Browsing by an unusually large population of white-tailed deer is the primary cause of many of these regeneration failures. In this study, vegetational surveys were made of the woody and herbaceous plants inside and outside 20, 13-year-old, 1 ac deer exclosures in the Allegheny National Forest, Pennsylvania. Deer browsing had reduced the height of the seedlings in the unfenced areas, thereby maintaining large numbers of smaller stems. In the fenced areas, seedlings grew to normal height, and the competition that resulted from crown closure reduced the total number of stems present. Deer browsing also caused a significant reduction in Rubus sp. and a corresponding increase in grass and sedge in the unfenced areas. North. J. Appl. For. 6:162-165, December 1989.
