Supporting the YBI Habitat Management Plan and Bringing YBI to TI!

The Yerba Buena Island Habitat Management Plan (HMP) calls for ongoing volunteer stewardship as well as contracted technical natural areas management of Yerba Buena Island's Natural Areas. As part of HMP implementation, this Public Stewardship Program currently facilitates public engagement through hands-on volunteer stewardship opportunties maintaining Yerba Buena Island's outstanding Natural Areas. 

TIDA and SFE also seek to "bring YBI to TI" by hosting volunteer days at a native plant nursery on TI (managed by Literacy for Environmental Justice-LEJ) and enhancing areas around Treasure Island community facilities with the installation of, and care for, YBI Native Plant Demonstration Gardens and providing hands-on learning opportunities for students at the on-Island Life Learning Academy High School.  Stewardship opportunities are suitable for all ages and abilities.
