California State Parks, with support from CAL FIRE and the Marin County Fire Department, is planning a prescribed burn of up to 260 acres at Angel Island State Park beginning as soon as Tuesday, September 8, with work potentially continuing throughout the week depending on conditions.
The burn is intended to reduce fuel loads in the island's grasslands and coastal scrub, while supporting wildlife habitat improvement and invasive plant management, according to State Parks. The project is funded by Proposition 4, the 2024 Climate Bond.
Residents across the San Francisco Bay Area are likely to see smoke from the burns between 9 a.m. and 6 p.m. on burn days, with smoke potentially visible for up to three days following ignition. State Parks asked community members not to call 911 to report the smoke, saying it would overwhelm emergency dispatchers.
Angel Island State Park will remain open during the burn, but some trails and roads near the burn area, including portions of the Ida Trail and Sunset Trail and the park's fire and perimeter roads, will be closed for one to three days during and after the work. Access to the summit of Mt. Livermore also will be restricted on some burn days. If weather and air conditions are not suitable for smoke dispersal, the burn will be rescheduled.
