Milagra Ridge Habitat Restoration Project

Lower Milagra Ridge, dedicated to the Golden Gate National Recreation Area in 2007, connects Milagra Ridge to a trailhead at the Connemara housing development.

The restoration project will protect and restore habitat for the endangered Mission blue butterfly. These fragile creatures lay their eggs on silver leaf lupine plants growing in open grasslands. The newly hatched caterpillars will feed only on the lupines. Invasive plants such as pampas grass, broom, and Monterey pine and cypress trees overrun these critical areas needed for the lupines, caterpillars, and butterflies to survive. This project will remove the most aggressive plants in the most critical areas.

For your safety, there will be temporary trail closures. The National Park Service appreciates your patience during removal of invasive vegetation. Work will occur Monday through Friday from 7 a.m. to 3:30 p.m. Info: call 415-561-3054 or email
