摘要

We studied avian response to clearcutting and to intermediate tree harvesting attwo elevations (lower wet sites and higher dry sites) within a greentree reservoir (GTR) on the Duck Creek Conservation Area (CA), southeastern Missouri, from July 1985 to September 1989. We utilized 24 circular 0.84 ha treatment plots that were randomly established as part of a collateral study of pin oak regeneration in Pool 3, Duck Creek CA within dry and wet areas delineated during flooding and dewatering operations. Eighty-seven avian species were recorded during the study, including 66 species that nested or otherwise use the study area as summer residents and 21 species that occurred exclusively as migrant winter residents. Twenty-five of the summer resident species also occurred during winter, for a combined total of 46 wintering species. Seasonal mean detections per plot (D), mean bird species diversity (BSD, H'), and mean species richness (S) differed among treatments when years and elevations were pooled and differed among years when elevations and treatments were pooled.
