Yerba Buena Island Stewardship

The next Stewardship Volunteer Day is Saturday November 16th from 12 PM to 2 PM!  We will be working at Treasure Island YMCA on TI installing a YBI Natives Demonstration Garden!


The Treasure Island Development Authority (TIDA) and San Francisco Environment (SFE) have proudly established the Yerba Buena Island Public Stewardship Program, hosting monthly public Habitat Restoration Volunteer Days on Yerba Buena Island and also offering special opportunities for school field trips, group and corporate stewardship volunteer experiences, and more!

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 offers individuals and groups an opportunity to perform hands-on volunteer stewardship and maintenance of Yerba Buena Island's outstanding Natural Areas.  The opportunities available are suitable for all ages and abilities.
