Description

Sugar maple decline began to affect Allegheny Plateau forests in the early to mid-1980s. The forests of the region were exposed to several stresses In the period frorn 1985- 1996, including droughts during 1988, 1991, and 1995. Additionally, both native and exotic insects reached epidemic levels during this period (see, for example, Rhoads, 1993). Other documented stresses in the region include past and present harvesting practices (Allen and others 1992), herbivory by deer (Tilghman 1989), and low soil nutrient availability (Long et al. 1997, DeWalle and Swistock 1997) possibly associated with soil acidification (Hendershot and Jones 1989).
