The Livestock and Range Management Program focuses on efforts to keep range livestock and the rangeland itself healthy and productive, and to encourage the healthy coexistence of introduced livestock and native plant and animal species in the range environment.

University of California Cooperative Extension's Livestock and Natural Resources website is designed to provide research-based and scientifically sound natural resource management information for rangeland owners, managers, and livestock producers.

California Rangelands Research and Information Center website has links to water quality, California vegetation, and livestock production information.
