Tuleyome, the organization on the Berryessa Snow Mountain National Monument, is offering a Certified California Naturalist course in early 2026.
The Certified California Naturalist course is presented by Tuleyome in partnership with the University of California Extension program. This multi-week course is offered from January to March 2026, with classes occurring on eight consecutive Fridays plus at least three field trips. Friday classes will be held in downtown Woodland.
According to a local press release, instruction focuses on the Berryessa Snow Mountain National Monument region and western Sacramento Valley while providing participants with skills and resources that are applicable anywhere to increase their knowledge, understanding and enjoyment of the natural world.
No advanced degrees or previous naturalist experience is required.
The UC California Naturalist Program introduces Californians to the wonders of our unique ecology and engages the public in study and stewardship of California’s natural communities. The program uses a science curriculum, hands-on learning, problem-solving, citizen science and community service to instill a deep appreciation for the natural communities of the state and to inspire individuals to become stewards of their local resources.
In addition to in-person instruction, students are required to attend field trips in the Berryessa Snow Mountain National Monument region and western Sacramento Valley. Field trips consist of low-impact walking trips and auto-tours, so they are suitable for all fitness levels. Impromptu walks are also often provided by the instructors, as time permits, to give participants even more experience in the field.
Tuleyome has offered the Certified California Naturalist course since 2018. In that time, over 200 naturalists have been certified and are dedicated to conserving, enhancing, restoring, and enjoying the Berryessa Snow Mountain National Monument region and the western Sacramento Valley. Lifelong Californians and recent arrivals benefit from the course.
The program has been so successful that Tuleyome has been requested to provide training to the Bureau of Reclamation – Lake Berryessa, Sacramento Regional Conservation Corps, and California Conservation Corps. In addition to the multi-week course, Tuleyome offers a one-week, intensive course at Wilbur Hot Springs Resort.
