The University of California Agriculture and Natural Resources operates nine Research and Extension Centers (RECs). Extending from the Oregon border in the north, through the Sierra Foothills and Central Valley, along the Pacific Coast and south to the Mexico border, the REC System provides a premier research management organization supporting the efforts of county- and campus-based academics, as well as researchers from land grant institutions in other states, the California State University system, and the United States Department of Agriculture. Our centers are also focal points for community participation and active involvement in regional agricultural and natural resource challenges.
