The California Naturalist Program promotes environmental literacy and stewardship through discovery and action. Many other states have similar naturalist programs, but this is the first statewide program in California. To become a certified California Naturalist, join our 2025 class at the UC Hopland Research and Extension Center.

Courses combine classroom and field experience in science, problem-solving, communication training and community service.

The class runs across six Saturdays in 2025 (2/8, 2/22, 3/8, 3/22, 4/5, 4/19). Each class will include classroom and field time at the UC Hopland Research and Extension Center. Classes will run from 8:30am-5pm, with graduation from 10am-1:30pm
