Join the Mendocino California Naturalist Community, Classes starting January 2024

Are you looking to learn about the wonders of our local ecology? The University of California’s California Naturalist class is open for registration once again in Mendocino, at the UC Hopland Research and Extension Center (HREC). 
The California Naturalist Program seeks to foster a committed corps of volunteer naturalists and community scientists trained and ready to take an active role in natural resource conservation, education and restoration. The course introduces participants to the wonders of local ecology, engages them in the stewardship of California’s natural communities, and introduces cultural connections with the landscape. Classes combine a science curriculum with guest lecturers, field trips and project-based learning to immerse participants in the natural world of inland Mendocino County. The class runs from February 10 to April 27, with 6 Saturday classes and field trips to the beautiful oak woodlands and rangelands of the 5,358 acre site at HREC. This class will fill quickly so interested members of the community are encouraged to register early to avoid disappointment. Class size is limited to 25 participants.
