We're lively, sweaty folks from throughout the East Bay and beyond who get together pretty much every week to remove invasive weeds and replant native species in Redwood Regional Park, the Sausal Creek Watershed, Sibley and Huckleberry Regional Parks, and adjoining open space and wild lands throughout the Greater East Bay Hills Ecosystem. We help beautiful native plants and wildlife return to places from which they had been absent, get lots of fresh air and exercise in the process, and have great fun besides!!
