Across the southeastern United States, there are several different species of Rubus (Blackberry and Dewberry). Blackberry is a common issue for pasture owners, with it also commonly growing in fence rows, and ditch banks. Lack of management will result in well established thick stands that grow rapidly. These large stands not only reduce pasture production, but also can result in some injury to animals from the thorns.
