Intermittent Trail Closures Park-Wide, Weekdays Feb 3–Apr 1
Treatment of oxalis and other invasive weeds on San Bruno Mountain will occur between Monday, February 3 and Tuesday, April 1. The work is expected to take up to 17 days, as weather and the availability of work crews allows, and will occur on weekdays only. Closures will take place in work areas and will require temporary closures on the following trails:
- Saddle trail
- Old Ranch Road Trail
- Dairy Ravine Trail
- Summit Loop Trail
- Eucalyptus Trail
- Ridge Trail
- Social trail from Hillside Blvd to the Ridge Trail
- PG&E road from Quarry Rd to the Ridge Trail (Buckeye Ridge)
- Social trail from Royce Way to the Summit Loop Trail
Treatment goals include the protection of native habitat from Oxalis pes-caprae and other non-native plants, which spread quickly and outcompete native plants. This work will involve targeted foliar application of the herbicide imazamox or triclopyr directly to foliage of the plants. The trails will reopen once application process, including drying, is complete.
