Improper management of livestock grazing has proven to be detrimental to rangeland and wildlife populations. The effects of poor grazing management are well documented, Fleischner ( 1994) identified the ecological costs of livestock grazing as the loss of biodiversity, reduced population densities of a wide variety of taxa; disrupted ecosystem functions, including nutrient cycling and succession; changes in community organization; and changes in the physical characteristics of both aquatic and terrestrial habitats. Fleischner (1994) described livestock grazing as the most pervasive land use in North America and the most important factor limiting wildlife production in the West. EFFECTS OF LIVESTOCK GRAZING Livestock grazing is considered by many to be detrimental to native wildlife habitats and rangeland.
