Effects of Stream Channelization on Avian Diversity and Density in Piedmont Virginia

Species diversity and density for game and non-game birds were studied during winter and summer, 1975 on three streams in the Virginia Piedmont which were channelized 2,5, and 9 years prior to Held work. Three study sites, each 1 hectare in size, were located along streams in secondary succession bottom land hardwood communities. Indices were calculated for bird species diversity (BSD) and foliage height diversity (FHD) using the Shannon-Weaver information theory formula. To further assess any differences in either diversity or density among the three sites the following variables were...
