Thank you for your patience during this new website transition.

Cooperative Extension was started in 1914, to help farmers, homemakers, and youth use the latest university research to improve their lives. At first geared towards strengthening rural areas, Cooperative Extension became integral to urban and suburban communities as well. A century later, Cooperative Extension continues to provide a vital link between public universities and communities.

In Sonoma County, the UC Cooperative Extension academic staff is at the forefront of change, working to preserve agriculture, helping communities shape wise public policy, and strengthening community development and leadership in our youth and adults.
