After two successful years of courses in 2017 and 2018, thanks to the collaboration of Lindsay Wildlife ExperienceSave Mount Diablo, and the Mount Diablo Interpretive Association, the Mount Diablo Region CalNat class is back this Fall 2019! 

Named for Contra Costa county’s iconic 3,849-foot peak, 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. Team-taught by lead instructor Jessica Kraft, certified Diablo California Naturalists, and local expert guest speakers, the Mount Diablo CalNat class provides a broad overview of California natural history while helping participants to become skilled interpreters, citizen scientists, and stewards of the lands and lives around Mount Diablo.

Through three weekend field trips, classroom instruction, and hands-on exercises, participants will observe and learn about the variety of ecosystems in our region. Participants will develop their ability to observe and engage with nature through keeping a field journal, contributing to a class citizen science project, making observations on the app iNaturalist, and completing capstone projects.

Course Dates: One weekday evening TBD, from 6-8 PM, and some Saturday afternoons beginning August 20 and ending November 5. The application for the course will open in May 2019.
