Re-examination of the relationship between constructed impoundment age and waterbird use / by Josette L. Maillet, Collin M. MacKinnon and J. Bruce Pollard. : CW69-5/290E

Cover image

The relationship between impoundment age and waterfowl and wetland obligate bird use of 32 selected freshwater impoundments in the Chignetoc border region was examined in 1996. Previous studies have indicated that primary productivity declines with impoundment age after initial flooding. Waterfowl and marshbird productivity was assumed to decline with impoundment age as well, concurrent with the observed decline in nutrient levels. An examination of wetland avifauna use versus age of impoundment was the focus of this study.--Abstract
