  • A separate division within the UC system, UC ANR is comparable in size and complexity to a small UC campus.

  • UC ANR creates innovative and locally relevant research, and develops and implements targeted education and outreach programs through the statewide network of UC Cooperative Extension.

  • UC ANR works across disciplines within five strategic initiative areas: endemic and invasive pests and diseases; healthy families and communities; sustainable food systems; sustainable natural ecosystems; and water quality, quantity, and security.

  • UC ANR employs a total of 1,350 individuals, working across all of California’s counties, at nine Research and Extension Centers, at three UC campuses, and at three administrative hubs.

  • UC ANR currently maintains more than 60 UC Cooperative Extension offices in California’s counties. More than 200 UCCE advisors and specialists operate from these offices alongside their programmatic and administrative support colleagues.

  • More than 320 UCCE academics are actively engaged in research and extension projects.

  • UCCE partners with more than 700 campus-based Agricultural Experiment Station faculty at UC Riverside, UC Berkeley, and UC Davis.

  • The UC ANR website and associate pages draw more than 90 million page views each year.
