Welcome to SF Natural Areas!! This site is for, by, and about the volunteers who work to preserve and protect the remnant habitats within San Francisco.

Unlike most other major urban areas, San Francisco’s steep topography has prevented the sort of torched-earth development that completely obliterated all traces of original landscapes elsewhere. In fact, 1100 acres (that’s 27%) of the San Francisco parks system are officially designated Significant Natural Resource Areas because they still contain irreplaceable biological communities. Other mostly-pristine remnant areas are owned by other public entities including the Public Utilities Commission and the Presidio Trust.

These public lands are under constant threat, however, from invasive weeds and over-use — and this is where volunteers come in. Volunteers with the Natural Areas Program of the San Francisco Recreation and Park Department (RPD) contribute tens of thousands of hours each year pulling weeds, maintaining trails, and propagating and planting native plants.

In fact, Natural Areas Program volunteers constitute over 25% of all RPD volunteer hours even though the Natural Areas Program has only 2% of RPD staff and receives only 1% of the RPD budget. The Natural Areas Program is underfunded and understaffed by a factor of ten. Volunteers are what prevent these priceless biological assets in San Francisco from collapsing into weedy ruin.

Anyway, other natural areas managers besides the SFRPD include the Presidio Trust which runs its own volunteer program; the National Park Service, which runs the Golden Gate National Recreation Area; the SF Public Utilities Commission which owns important remnant areas near Laguna Honda; and UCSF, which owns and manages Mt Sutro. Plus, there are other important groups which play crucial roles in San Francisco’s preservation of its biological heritage.

However, what has been missing is a site where volunteers can post their photos and tell their stories about working in these remarkable areas. That need is what this site attempts to fill. This site also, over time, may become an integrated botanical guide to San Francisco’s native plants, though this be an over-ambitious goal.
