At San Bruno Mountain Park
Every 4th Friday & Saturday of the Month, 9am – 12noon

Volunteer to save critical grasslands at San Bruno Mountain Park. Join the SSF Weed Warriors for fresh air and exercise and help them weed on the south slope of mountain. The south slope has large areas of grasslands that are critical to resident endangered butterflies. The focus is to remove invasive non-native plants.

Workdays are on the 4th Friday and Saturday of the month. So there are opportunities for those who would prefer a weekend workday. You’re welcome on either day, or come both days – even better!

• gloves provided
