Tuleyome’s Certified California Naturalist (CalNat) program trains members of the public to become California Naturalists! No advanced degree or previous naturalist experience is required – Tuleyome teaches you everything you need to know to become certified. Our course is focused on the northern inner Coast Range mountains, specifically the Berryessa Snow Mountain National Monument region.


The program, developed by the University of California Agriculture and Natural Resources, 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 California Naturalist program uses science curriculum, hands-on learning, problem-solving, participatory 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.


Courses combine classroom and field experience in science, problem-solving, communication training and community service, taught by an instructor and team of experts. Upon completing certification requirements, participants are eligible for academic credits through UC Davis Extension for an additional nominal fee.


Teaching Modules Include:

  • A “Nature Table” for sharing field journals and photos of specimens found in the region
  • An overview of the chapters of the textbook, along with more targeted information about our region with a focus on vocabulary
  • Guest lecturers
  • Guided field trips
  • Hands-on learning experiences
  • And our very popular “Species Identification Modules” during which we will go over various common species found in the region and tell you some fun facts about them
