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A vast majority of the information in the database was gathered from project websites and may be out of date.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)
Conduct surveys to help manage the salmon resource in the Big River watershed and maintain the overall biodiversity of the watershed.
Other goals include: 
  • Foster student stewardship of natural resources
  • Collaboration among students, teachers, community members and practicing scientists
  • Maintenance of reliable and high quality databases
  • Provide job shadowing and career awareness in Natural Resource management
  • Provide training and equipment for Natural Resource monitoring
Participant Activities

Students conduct field studies to observe and estimate adult and juvenile Coho populations by counting adult carcasses and redds on the Little North Fork of the Big River. Students follow salmon survey protocols developed by the DFG.

The School of Natural Resources (SONAR) is an advanced placement environmental science class based in Mendocino High School with an emphasis on doing field research and restoration work. Field studies gather population data for research, study, and analysis of the changes in the Big River watershed.

Data Entry
  • Unknown
Other Participant Activities

Volunteers can become involved in the Students for Environental Action (SEA) groups, tours of the local ecology, and other SONAR initiatives.

System Studied
  • Water Quality
  • Wetlands - Freshwater Streams and Marshes
  • Other (see Notes)
Geographic Scope
Big River watershed
Location - Map
10700 Ford Street Mendocino, CA 94560
Time Commitment
  • Weekly
  • Other (see Other Information below)
Volunteer Qualifications

Volunteers are primarily high school students, though opportunities exist for teachers and university students.

Volunteer Training

Students will be trained to collect and present information in a scientific way about the conditions of local streams and marine habitat. Students also learn how ecosystem managemenet can be an ethic for wise stewardship of resources here on the Mendocino coast and elsewhere, and how SONAR can be a pathway for students' future careers in a field related to natural resource mangaement or in higher educational settings.

Cost to Participant
How will the findings be used?

Data are used by the California State Dept of Fish & Game to augment missing information on the Little North Fork of Big River, helping them manage the salmon resource in the Big River watershed.
