Description :
This study examines a forested riparian natural area in the Allegheny River managed as a wilderness but situated downstream from a large dam. The AA. analyze the vegetation dynamics of this site as an indicator of the role of dams in affecting the disturbance regime of riparian zones in the eastern deciduous forest region. Specifically, this study identifies the landscape patches present on the site to determine the disturbance related successional pathways operating in them, the life-history characteristics they favor, and the resultant implications for species composition.
