Let yourself go wild

We're inspired to increase the understanding of our local native flora and to preserve our natural heritage for future generations. Why? There’s no place quite like San Francisco and northern San Mateo Counties. Over 540 native plants grow in San Francisco alone, 48 of which are threatened. We're fortunate to live in a biodiversity hotspot.

Help us make sure these vital resources for birds, butterflies and bees are invasive weed-free and protected.

Volunteer with Yerba Buena

Please consider joining our efforts to promote native plants and biodiversity in beautiful California. Of the 469 native plants that are known to exist in San Francisco today 24 of those are listed as threatened species. We are working especially hard to bring these marginalized species back to healthy populations but we need you to help us!
