Help spread lupine seeds in the grassland habitat of the endangered mission blue butterflies!

We are partnering with the Creekside Center for Earth Observation to sow thousands of native lupine seeds (produced from San Bruno Mountain plants) this Fall! Silver, summer, and varied-color lupines are the host plants of the mission blue butterflies.

Join us as we hike the mountain, disperse seeds, and enjoy panoramic views. Sign up below to participate! We will also be partnering with the South San Francisco Weed Warriors for this event, which takes place within the critical habitats they steward on the mountain’s south slopes.
