Effects of Alligatorweed Control in Seasonal Wetlands Managed for Waterfowl

SEAFWA Journal Volume 9, March 2022
Wildlife Outstanding Technical Paper

Wildlife managers commonly use herbicides to control invasive plant species and maintain early-successional vegetation communities in seasonally flooded moist-soil wetlands. However, there is limited information on how herbicides influence plant and animal communities following application. Thus, we investigated the response of vegetation, food density, and the abundance and activities of dabbling ducks (Anatini) to application of imazapyr herbicide in moist-soil wetlands in Tennessee to control invasive alligatorweed (Alternanthera philoxeroides). Imazapyr...
