Stewardship Saturday on the Northeast Ridge

  • The Ridge 31 Lupine Valley Ct Brisbane, CA, 94005 United States (map)

The City of Brisbane and San Bruno Mountain Watch invite you to an enjoyable summer morning of habitat restoration on the golden hills of the mountain's northeast ridge.

The Guadalupe Hills, the northern extension of the San Bruno Mountain range, are home to two of the mountain's endangered butterfly species, the mission blue butterfly and the callippe silverspot butterfly.

These special butterflies live in open grassland areas where their host plants and various native wildflowers thrive.

Yet, their grassy homes are threatened by invasive woody shrubs that can completely cover them up. You can help control these invasive shrubs, commonly known as "broom," and prevent them from spreading further!

When: Saturday, June 25th from 9am to 12pm - NEW TIME

Where: The meeting location will be on the sidewalk at the merger of Lupine Valley Ct and Butterweed Lane at the Ridge development (see map:

What: Help protect endangered butterflygrassland habitat by cutting down and removing invasive shrubs. Tools, gloves, and educational information about the mountain and the butterflies will be provided. Lunch will be served after the event.
