Las Positas College
Course Description
Discover the rich natural and cultural heritage of the Mount Diablo Range and East Bay Hills in this California Naturalist course. Through a blend of online classes with guest lectures, and in-person field trips, participants explore the region’s diverse habitats—from oak woodlands and chaparral to serpentine grasslands—while learning about its geology, ecology, and deep cultural significance to Indigenous peoples. The Mount Diablo region stretches from Pittsburg and Antioch all the way to Corral Hollow, southwest of Tracy, and includes many regional parks, city open spaces, state parks, and reservoirs. This class provides a broad overview of California natural history while helping participants to become skilled interpreters, participatory scientists, and stewards of the lands and lives around Mount Diablo. Participants who complete the course are certified as UC California Naturalists and are eligible for 4 undergraduate units through UC Davis. Within the framework of the UC Environmental Stewards, this course combines science, service and place-based learning.
