Aquatic Invertebrate Biomass in Coastal South Carolina Impoundments Managed for Waterfowl

Wildlife Outstanding Technical Paper
Production of submersed aquatic vegetation (SAV) is promoted for waterfowl forage through hydrological management in brackish tidal impoundments along the south Atlantic coast, USA. This management also promotes production of aquatic invertebrates as food resources for many bird species. We conducted a field experiment to compare effects of traditional complete drawdown to fissure substrates versus a novel partial drawdown (i.e., mudflat to 10 cm depth) on aquatic invertebrate biomass in impounded and non-impounded tidal wetlands in the Ashepoo, Combahee, and Ed- isto Rivers (ACE) Basin,...
