Tuleyome’s Certified California Naturalist course will focus primarily on the Berryessa Snow Mountain National Monument region (which includes parts of Yolo, Solano, Napa, Lake, Mendocino, Glenn and Colusa Counties). By signing up for the course with Tuleyome, you also become a CERE Guardian - an active member of the public dedicated to Conserving, Enhancing, Restoring and Enjoying our regional public lands and open spaces - and will receive a special pin at the completion of the course.

Students will participate in at least 40 hours of classwork and three field studies, and will complete a capstone project. Tuleyome offers 2 courses: the first delivers the curriculum over a series of 10 weeks. The course is open to members of the public age 21 years and up and limited to 30 students. The second course delivers the curriculum within one week (immersion).
