Planting, Weeding, & Clean-Up at Owl Canyon

  • 69 South Hill Drive Brisbane, CA 94005 (map)
Name *
Volunteer Activity Preference *

Join San Bruno Mountain Watch, the City of Brisbane, and the Open Space & Ecology Committee at Owl Canyon on February 9th! 

Please check-in at 9:45am, as the group will begin promptly at 10am.

Volunteers will be planting native grasses, host plants, and nectar plants from Mission Blue Nursery to improve the grassland habitat of the Mission Blue and Callippe Silverspot butterflies.

Please sign up to secure a planting spot! Planting areas are tightly clustered, so the number of planters will be limited to 20 or so people to avoid overcrowding in these sensitive habitat areas. Those interested in planting must arrive on time, as we will be hiking away from the meeting location.

Other activities will include removal of invasive shrubs and trash clean-up at the bottom of the canyon.

Gloves and tools will be provided, so please leave personal garden tools at home. Sturdy shoes, sun protection, and a reusable bottle of water are recommended.

Community picnic afterwards! If you’d like to join, feel free to bring a dish to share.

Driving Directions to Owl Canyon

1) From Bayshore Blvd, turn onto Valley Drive, the entrance to Crocker Industrial Park in Brisbane. 

2) Drive down Valley Drive and turn left at the stoplight at the intersection of Valley Drive and South Hill Drive 

3) Drive a very short distance on South Hill Drive; immediately after a pedestrian crosswalk, as the road begins to curve, you'll see a steep driveway on your left with potholes. Turn into that steep driveway and drive up.  (Use "69 South Hill Drive, Brisbane, CA 94005" for navigation systems to reach this driveway)  

4) At the top of the driveway, park parallel to the drainage ditch next to the Canyon.

5) The first canyon on at the top of the driveway is Buckeye Canyon. Owl Canyon is further down the road, about a three minute walk. Meet at the base of Owl Canyon, where the unofficial “skate park” is located. See this map:
