Plantings of perennial and biennial forage, such as white clover (Trifolium repens), red clover (Trifolium pratense), and alfalfa (Medicago sativa), commonly are used by managers to increase nutritional resource availability for white-tailed deer (Odocoileus virginianus). Regular mowing and selective herbicide applications are two common practices used to maintain perennial plantings and reduce weed competition. However, there is little information available on how these management activities influence perennial forages or wildlife response. We evaluated...

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...

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...
