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A vast majority of the information in the database was gathered from project websites and may be out of date.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

    Monitor trends in the distribution and abundance of tricolored blackbirds. The statewide survey provides current, reliable information on the numbers and distribution of tricolored blackbirds throughout California and a means to document trends in the population over time. The survey complements more intensive field efforts that provide insights into the factors causing observed population increases or declines.

  • Participant Activities

    Participants work independent or in groups to visit tricolor sites and document both presence and absence, along with an estimate of the number of tricolors and characteristics of occupied sites. The statewide survey occurs every 3 years. The observation portal is accessible and may be used by partner organizations more frequently.
