Volunteering with San Bruno Mountain Watch is an ideal opportunity to get outdoors, become intimate with a local native ecosystem, and help protect the beautiful biodiversity of San Bruno Mountain. It's also a great way to meet a new community of people dedicated to caring for our environment.

Our volunteer programs are dedicated to the restoration of multiple native ecosystems on San Bruno Mountain. We lead stewardship activities that enhance the habitat of the mountain’s endangered butterflies and protect its unique native flora.  Stewardship volunteers work on grass prairies and wetlands to remove invasive species and plant native vegetation. Nursery volunteers help grow locally native plants for habitat restoration and landscaping purposes at our Mission Blue Nursery.

We host ongoing volunteer opportunities multiple days each week. Please feel free to join us at any one. If you’d like to get involved in restoration work on the mountain, please email Ariel Cherbowsky, our Stewardship Coordinator, at ariel@ mountainwatch.org; if you’d like to get involved at the Mission Blue Nursery, please email Ildiko Polony, our Nursery Manager, at ildiko@mountainwatch.org or call the office at 415 467 6631. Bring sun protection, warm clothes in layers, sturdy shoes, and make sure to wear clothes that you don't mind getting muddy. We provide snacks, but it's best to bring your own water bottle.

Below are descriptions of our volunteer opportunities. Please check our Events page for updated scheduling.

 

SATURDAY MOUNTAINEERS

Volunteers planting seedlings on San Bruno Mountain from the Mission Blue Nursery.

Stewardship Mountaineers work all over the mountain and help protect and improve the mountain’s sensitive and unique habitats, directly benefiting the mountain’s endangered species and native plant communities. We work every Saturday from 10am to 1pm, removing invasive vegetation or planting native plants supplied by our Mission Blue Nursery. We often work in Buckeye and Owl Canyons in sensitive endangered butterfly habitat, but also work in the mountain's "saddle" and in other areas. Please be sure to check the Events page for a description of the work and for directions to the work site, as it may vary. Transportation to the site is available but must be arranged in advance by emailing ariel@mountainwatch.org to reserve a spot in the carpool which departs from the Mountain Watch office at 9:30am.

 

 

WEDNESDAYS AT THE MISSION BLUE NURSERY

Volunteers are welcome to join us every Wednesday from 10am to 12:30pm at the Mission Blue Nursery. Activities vary depending on the season, but may include planting seeds collected from the mountain, transplanting seedlings, washing pots, and processing seeds collected from the mountain. Drop-ins welcome. Bring hats, sunscreen, and water. Contact Ildiko@mountainwatch.org or call 415 467 6631 for more info.

GUADALUPE VALLEY STEWARDS

Watch a video about our work in Guadalupe Valley.

Tucked behind a parking lot in Guadalupe Valley's Crocker Industrial Park is a small stream and wetland that has been lovingly restored by volunteers. The valley was once a mix of grassland and wetland, drained by multiple tributaries that fed into a salt marsh mingling with the San Francisco Bay. A joint project with the City of Brisbane, this gem is also a Pacific chorus frog habitat, ringing with delightful "ribbits"!  Guadalupe Valley Stewards meet on Tuesday mornings from 10:00 AM 12:00 PM to keep this area clean of debris and invasive plants. Bring boots if you have them! Tools and snacks will be provided. Check our events page to find directions to the work site each week.

 

 

The southern slopes of San Bruno Mountain

fridays and saturdays in South san francisco

Our South San Francisco Weed Warriors restore sensitive butterfly habitat on the south slope of the mountain. Work involves removal of invasive non-native species from grassland areas. The south slope of the mountain still has the largest areas of grasslands that are prime habitat for both the Mission Blue and Callippe Silverspot butterflies.

The two consecutive workdays are the 4th Friday and Saturday of each month from 9:00 AM until 12:00 noon. Please check our events page to confirm workday dates.
