UC California Naturalist Program

A statewide program of the University of California's Division of Agriculture and Natural Resources, the UC California Naturalist Program is designed to introduce Californians to the wonders of our unique ecology, engage the public in study and stewardship of California’s natural communities, and increase community and ecosystem resilience.

The mission of the UC California Naturalist Program is to foster a diverse community of naturalists and promote stewardship of California's natural resources through education and service.

The UC California Naturalist Program is the hub of a collective impact network. We currently offer two certification courses: UC California Naturalist and UC Climate Stewards. To become a certified California Naturalist or UC Climate Steward, participants need to complete a 40+ hour course. Read more about us or find a course near you.
