Grazing management strategies have been used to achieve wildlife conservation objectives. Three case studies reveal how livestock grazing is the most widespread land management practice in the world. A comparison of three different types of rotational grazing systems at the Fort Pierre grasslands of South Dakota revealed some grazing strategies were more likely to fulfill standing cover requirements than others for prairie grouse. A rotational grazing system was established in 1984 to address forage conflicts between elk and livestock on Mount Haggin Wildlife Management Area in Montana. Conflicts over elk on private lands, cover and forage availability, and adjacent landowner relations were improved using rotational grazing to fulfill various conservation objectives in Montana. Grazing exclosures were erected as wildlife habitat enhancement projects along riparian areas in Pennsylvania. Researchers concluded that a carefully-designed grazing system would provide for larger and diverse small mammal populations as compared to continuous season-long grazing.
