Map of Local & Regional Projects

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A vast majority of the information in the database was gathered from project websites and may be out of date.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) Discover weeds before they become well-established to reduce damage to ecosystem integrity, prevent the loss of habitat for rare plants and animals, and prevent costly natural resource management. 

 Participant Activities Weed Watchers survey trails and roads in spectacular locations throughout the Golden Gate National Parks to identify and map weeds as they first invade. Join staff and lead volunteers on excursions to search for the priority weeds of the park. Gain expertise on the native and invasive plants of the Bay Area, and learn to use your digital camera, smart phone, or GPS unit to report weed sightings to park managers via the Internet.

 Data Entry Website, Cell Phone, Other
 System Studied Invasive Species
 Geographic Scope Regional
 Region Northern California
 Location Golden Gate National Parks throughout San Mateo, San Francisco, and Marin counties.
 Location - Map 201 Fort Mason, San Francisco, CA; 1 Bear Valley Road , Point Reyes Station, California
 Time Commitment Specific dates (see Other Information below), Other (see Other Information below)

  • Bring your own lunch, plenty of water, binoculars (if available), pen/pencil, and field notebook/blank paper.
 Volunteer Training Extended training in invasive plant identification and mapping is available (but not required for group hikes). Trained volunteers conduct independent surveys, and report new weed occurrences to the parks. 
See website for calendars of upcoming hikes and trainings in Golden Gate and Point Reyes. 

 How will the findings be used? Newsletters with Weed Watcher updates are published on the web and volunteers and public can download Google Earth weed map. 
Project is part of the San Francisco Bay Area Network Inventory and Monitoring Program (SFAN I&M) which aims to "improve park management through greater reliance on scientific knowledge" by working to "collect, organize, and make available natural resource data and to contribute to the Service's institutional knowledge by facilitating the transformation of data into information through analysis, synthesis, and modeling."
