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A vast majority of the information in the database was gathered from project websites and may be out of date.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 cghdixon@ucdavis.edu. 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)

    Describe the distribution and demography of otters on the coasts, wetlands and watersheds in Humboldt and Del Norte counties. The river otter (Lontra canadensis) is a key bio-indicator of the health of our environment as they sit at the top of this water-based food chain. Initial scientific goals are to:

    • Assess spatial and temporal variation in otter distribution
    • Assess spatial and temporal variation in pup production
    • Conduct observational studies on otter foraging
    • Conduct diet assessments
    • Assess home range and site faithfulness of individuals
  • Participant Activities

    Watch otters and detect signs of their activities along rivers and lagoons in Humbolt County and report observations
