摘要

Regeneration surveys in fenced and unfenced portions of thirteen 9- to 22-year-old clearcuts on the Allegheny Plateau of Northwestern Pennsylvania show that deer browsing has resulted in (a) inadequate stocking of tree species, (b) delay in establishment and (c) less valuable species composition. Ninety-two percent of the fenced areas, but only 38 percent of the unfenced areas, are considered satisfactorily stocked. The value of timber production lost as a result of browsing during the regeneration period is estimated to average $1,075 per acre.
