NORTHERN CALIFORNIA — Tuleyome is offering two Certified California Naturalist courses in 2023 — one in the winter and one in spring. Instruction focuses on the Berryessa Snow Mountain National Monument region.

The Certified California Naturalist courses are presented by Tuleyome in partnership with the University of California extension program.

The winter course will be offered from January to March in 2023.

This course is 10 weeks long, with classes on 10 consecutive Fridays, including at least three field trips.

The spring course is a one-week program hosted at Wilbur Hot Springs.

No advanced degrees or previous naturalist experience is required. Both courses cover the same material.

The UC California Naturalist Program is designed to introduce Californians to the wonders of our unique ecology and engage 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.

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.
