Certified California Naturalist Program


Do you love nature?  Do you want to learn more about local plant, animal and insect species? Do you want to learn about volunteer opportunities related to the natural environment?  Tuleyome is teaming up with the University of California's extension program and the Woodland Public Library to teach members of the public how to become Certified California Naturalists! No advanced degrees or previous naturalist experience is required.

The California Naturalist Program allows Californians to help protect and preserve our unique and diverse wildlife, habitats, river, lakes and coastal resources, wild and urban alike.  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.

To sign up for email updates about the course, just fill out the form near the bottom righthand side of this page.

There are only 6 seats left for the Winter 2018 class.  Sign up now to secure your spot!


Students who register for the course will participate in 40 hours of classwork and three field studies, and will have to complete a capstone project in order to graduate.  The adults only course is open to members of the public age 18 years and up.  Classes are limited to 20 students.

Classes will be held from 2:00 pm to 6:00 pm.

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).

Subjects covered in the course will include

  • Water
  • Plants and Plant Communities
  • Forest, Woodland and Range Resources and Management

Teaching will include:

  • a lecture by a guest speaker
  • a “species identification module” during which we will go over various common species found in the region and test the students for proficiency
  • field trips
  • and a “Nature Table” for sharing field journals and photos of specimens found in the region.

We’ve already got some great speakers lined up for you including: Petrea Marchand, from the Yolo Habitat Conservancy, Staff from the Putah Creek Council, Stephen McCord of McCord Environmental, Inc., Christina Lewis, of the Sacramento Chapter of the California Native Plant SocietySarah Matthews of the Bureau of Land Management, a special appearance by Hawks, Honkers and Hoots, and many others.

In addition to the course, certified Naturalists will be required to complete 40 hours of nature-based volunteer service (in one of four areas: program support, interpretation/education, restoration /conservation and/or citizen science) each year to maintain their certification. Yearly incentives are offered by the University of California for volunteers that log their hours.
