Sequential cattle and sheep grazing for Spotted Knapweed control: Author: Henderson, Stacee Lyn; Date: 2008-12-15; Program: Animal and Range Sciences; Abstract: Spotted knapweed (Centaurea stoebe L.) infests millions of hectares of native rangeland in North America. Spotted knapweed creates large monocultures, which decreases biodiversity, reduces livestock and wildlife forage, and increases surface water runoff and soil erosion. Sheep are an effective tool for controlling spotted knapweed and have been widely used on cattle ranches for weed control. However, cattle producers are concerned that sheep will over-utilize desirable graminoids. Therefore, research is needed to determine an effective grazing strategy using cattle and sheep that will adverse...; Download File | View full details
