Abstract
We evaluated the effects of revegetation techniques on breeding bird communities in a bottomland hardwood forest impacted by thermal effluent. In 1993, sections of the Pen Branch bottomland on the Savannah River Site, South Carolina, were herbicide-treated (glyphosate), burned, and planted; other sections were planted only while others were unaltered and served as controls. Few differences in the avian community occurred at 1 and 2 years post-treatment among treatments. Plots that were herbicide-treated, burned, and planted had greater species richness in 1994 and abundance in 1995 than sections that were planted only ( P<0.05). Bird species composition differed slightly among treatments and White-eyed Vireos ( Vireo griseus), Common Yellowthroats ( Geothlypis trichas), Indigo Buntings ( Passerina cyanea), and Red-winged Blackbirds ( Agelaius phoeniceus) were the most abundant species in the corridor. Revegetation techniques used to restore this thermally-impacted bottomland had little effect on the avian communities 1 and 2 years post-treatment.
