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A vast majority of the information in the database was gathered from project websites and may be out of date.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.

If you know of a project not on our list, please go to the "tell us about a project" link on the left so we can list the project here. Thanks for your help!

Special thanks goes to the National Science Foundation Informal Science Education program and the Stephen J. Bechtel, Jr. Foundation for supporting this database of projects.

Project Purpose (taken from project materials)

Monitor and assess water quality conditions in the Yuba River to contribute to the protection and restoration of waterways for healthy wildlife, safe recreation, and reliable water supplies.

Participant Activities

Volunteers visit their adopted sites monthly to test water quality conditions and record their observations.  In addition to routinely measuring many water quality parameters, volunteers monitor the presence of sensitive and invasive species, and occasionally test for bacteria, nutrients and toxic metals.  The program is based on the scientifically-credible Quality Assurance Program Plan approved by the Regional Water Quality Control Board.
