Grazing systems are established on private or public lands currently being over- grazed or poorly managed by grazing. These are primarily twice-over, deferred, and short-term grazing systems. This practice provides increased nesting cover, erosion control, and improved water quality for wetland complexes within the grazed area. In many instances, by initiating a profitable grazing system, a landowner may avoid breaking the prairie to make a go at cropping. Since 1987, grazing systems for 41,821 acres of primarily native pasture have been prescribed.
