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A vast majority of the information in the database was gathered from project websites and may be out of date.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

Document and help prevent the spread of Undaria pinnatifida, a quick-growing non-native kelp, also known as Asian kelp, which arrived to Southern California in 2000 and quickly spread north to Monterey. 

Participant Activities

Join "undaria removal events" to help identify and remove undaria in San Francisco Bay and Half Moon Bay.
Also, boat owners, harbor visitors and divers can inspect vessel hulls, boat slips, moorings, docks and piers. Volunteers photograph any suspected 
Undaria and email to program. If volunteers can safely remove the kelp, please do so, photograph and keep in a plastic bag in the refrigerator for identification purposes until scientists can respond to your information.

Other Information

There are opportunities for both independent and group participation. 

Here is a schedule of "undaria removal parties"

Wednesday, April 11 San Francisco Marina, San Francisco
Saturday, April 14 Pillar Point Harbor, Half Moon Bay
Sunday, May 13 Pillar Point Harbor, Half Moon Bay
Saturday, June 16 Pillar Point Harbor, Half Moon Bay

We begin at 9 am each day and meet in front of the harbor master's office at Pillar Point Harbor, Half Moon Bay and in front of Gate 14, which is in the East Basin (aka Gas House Cove) at San Francisco Marina, San Francisco. Typically we will work until noon or 1 pm.  Volunteers are needed to help remove kelp from floating docks and to collect and record data. It's a fun way to do something great for the Bay!

People should dress in layers, wear clothes that they don't mind getting dirty, and make sure to bring water, snacks, hat and sunscreen.
