Rangeland Management

Rangeland Management is an applied science focused on the stewardship of vast, uncultivated lands like grasslands, savannas, and shrublands to ensure their long-term health and productivity. It involves the careful manipulation of rangeland vegetation, soil, and water to achieve a balance among diverse objectives, such as producing sustainable forage for grazing livestock, providing critical habitat for wildlife, conserving water resources, and supporting recreational activities. Practitioners utilize principles from ecology, soil science, and animal science to develop strategies that prevent land degradation and promote a resilient ecosystem capable of supporting both agricultural needs and biodiversity.
