Beach Cleanups & Bioblitz

The Aquatic Stewards program is an ongoing volunteer program educating youth on marine ecosystems and species, and collecting data in a long-term study of terrestrial and marine sources while engaging the public to support our National Park and public beaches.

We are working with underserved youth in San Francisco and Los Angeles public schools learning ecosystem science and cleaning up the beach. Youth and citizen scientists record data and are mapping and identifying species in Aquatic Park Cove using iNaturalist with the California Academy of Sciences. We also train citizen-scientists to conduct Bio Blitzes in the Park with the community to observe and record species data in the Cove and nearshore. Join us at one of our events in San Francisco, Berkeley, Southern California and Hawaii!

We upload data on marine litter using the Marine Debris Tracker App, and Flora and Fauna observations to the  Aquatic Park Ecoblitz Project.

In 2019 and 2022 we have expanded our cleanups and wildlife surveys at Aquatic Park Berkeley, documenting shark and ray die-offs and working with the City and State to mitigate this hazard to wildlife and human health.

With our partners* our aim is to reduce plastic pollution in the Bay Tributaries, San Francisco Bay and adjacent beaches through direct action, education and policy. This campaign aims to raise awareness about the environmental impact of cigarette butt litter on our oceans, waves and beaches, and to help eliminate cigarette butt litter in San Francisco County and beyond to the Bay and Pacific Ocean.  Commonly littered on our sidewalks and streets, butts end up in our storm drains, flowing to our streams, rivers, bays, lagoons and ultimately the ocean.
