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...

Herbicides are Effective for Reducing Dense Native Warm-season Grass and Controlling a Common Invasive Species, Sericea Lespedeza

SEAFWA Journal Volume 3, March 2016

Practices within the Conservation Reserve Program promote planting native grasses and forbs to improve habitat for northern bobwhite (Colinus virginianus) and other wildlife. However, native grasses often become dense and stands can be invaded by undesirable plant species that reduce habitat quality. We investigated three herbicides (clethodim, glyphosate, and imazapyr) at two rates to reduce native-grass density and five herbicides (aminopyralid, fluroxypyr+triclopyr, glyphosate, metsulfuron-methyl, and triclopyr) at two rates to control sericea lespedeza (Lespedeza cuneata), a common...
