Northern CA PPSR Projects 1

Welcome to our ongoing effort to catalog citizen science and other public participation in scientific research (PPSR) projects for UC California Naturalists and other citizen scientists.  We invite you to browse the listed projects or enter key words (like birds, youth, invasive, coast, Alameda, etc.) in the search box above to find projects in your area. It's a great way to stay involved and keep developing your skills as a natural scientist!

A vast majority of the information in the database was gathered from project websites and may be out of date. We encourage you to contact projects directly to get involved and learn about most recent opportunities. If you work with a listed project and would like to add to, update, or correct the information we have, please email Also, please consider filling out the "PPSR perspectives" survey. Click here to access the survey, which will help guide this project in the coming year.
