Home to the mission blue butterfly, Milagra Ridge has been the focus of intensive Park Stewardship restoration and monitoring in San Mateo County.

Community volunteers are helping to restore Mori Point and improve habitat for the threatened California red-legged frog and the endangered San Francisco garter snake.

Just north of the Marin Headlands, Oakwood Valley features a hiking trail loop that winds through native grassland and the largest stand of oak and bay forest in the Golden Gate National Parks. The Parks Conservancy's Park Stewardship program works hard to protect these valuable resources by engaging the community and volunteers in restoration efforts.

Completed in May 2010, the Park Trail provides a north-south trail corridor through the Presidio, extending 1.7 miles from the 14th Avenue Gate to Crissy Field.

A collaborative effort of the Parks Conservancy, National Park Service, and the Presidio Trust, the award-winning parkwide sign plan greatly enhances visitor experiences.

The 2.1-mile Presidio Promenade is a major east-west trail bringing visitors from the park's urban edge at the Lombard Gate to the Golden Gate Bridge.

The Park Stewardship program has focused on removing invasive plants to restore the Mission Blue butterfly habitat at this site in Marin County.

Once a military site covered with asphalt and debris, Crissy Field was transformed into a beloved national park in 2001 thanks to the generosity and energy of the community.

After centuries of slaking the thirst of its denizens, El Polín Spring itself has been, well, refreshed. In 2011, a dramatic phase of improvements was completed by the Presidio Trust, Golden Gate National Parks Conservancy, and National Park Service.
