To become a certified UC California Naturalist or UC Climate Steward, you need to enroll in a 40+ hour course with one of our course partners. There are separate maps for UC California Naturalist courses (yellow tab) UC Climate Stewards courses (green tab) and Statewide Partners (blue tab). Statewide Partners include organizations that we collaborate with to meet our mission. They do not offer courses. Scroll below the map to view the course calendar and learn more about the benefits of joining our growing community.
