This event is hosted in collaboration with the City of Brisbane Open Space and Ecology Committee!

Help remove invasive weeds on San Bruno Mountain’s Northeast Ridge!

Please note that the work will take place on a steep hillside slope.

These stewardship efforts will help prevent invasive french broom from spreading into habitat for the endangered mission blue, callippe silverspot, and bay checkerspot butterflies.
