Switchgrass is a native grass that is widely used for erosion control, pasture and hayland planting, wildlife habitat, and native prairie restoration. It is also increasingly used as a renewable biofuel resource due to its high dry matter biomass yields. Forestburg Switchgrass is a variety that grows to 3-5 feet tall and is ideal for nesting and winter cover for pheasants and birds. It is a major component of the central North American tallgrass prairie and can be used for soil conservation, forage production, game cover, and erosion control. Switchgrass is tolerant of a wide range of soil conditions and is native to every state in the continental U.S. except for Oregon, Washington, and California. In Europe, research has just started on switchgrass as a biomass crop for energy and fiber production, and varieties must be chosen based on latitude of origin to ensure successful establishment, yield, quality, and long-term winter survival.
