Effects of Alligatorweed Control in Seasonal Wetlands Managed for Waterfowl

SEAFWA Journal Volume 9, March 2022

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 was...

Mallard Use of a Managed Public Hunting Area in Mississippi

SEAFWA Journal Volume 2, March 2015

Managers of public lands affording waterfowl hunting strive to provide quality hunting opportunities while supporting biological needs of birds during winter. Understanding responses by mallards (Anas platyrhynchos) to diurnal hunting activities would help shape hunt regimes that satisfy management goals. We examined use of a wildlife management area (WMA) in western Mississippi by 28 radio-marked female mallards when waterfowl hunting season was closed and during the season when none, half, or all of the WMA was hunted during two winters 2010-2012. The proportion of each day that mallards...
