The purpose of the San Bruno Mountain Habitat Conservation Plan is to provide guidance for developing scientifically sound management and monitoring plans for the conservation of: a) the habitat of the mission blue, callippe silverspot, San Bruno elfin and bay checkerspot butterflies, and b) the overall native ecosystem of San Bruno Mountain in perpetuity. This Habitat Conservation Plan is an implementation plan for the management and monitoring activities authorized in the HCP and is based on lessons learned from habitat management activities conducted over the past 33 years. These efforts have protected the core habitat areas (comprising approximately 1,290 acres) of the mission blue, callippe silverspot, and San Bruno elfin butterfly populations--the three known listed butterflies that occur on the mountain--from being overtaken by weed infestations and scrub encroachment. These efforts, however, have focused on the highest priority invasive species and current management and funding are incapable of controlling all invasive species that are present on the mountain.

Site Activity Review

The site activity review (SAR) process is used to review projects that are minor in scale, yet have potential to impact sensitive habitat areas within the San Bruno Mountain HCP area. Those interested in this performing any work that would disturb habitat in the conserved habitat should submit the San Bruno Mountain HCP Site Activity Review Application. Application processing will take a minimum of one month.


Staff administers the San Bruno Mountain HCP by reporting to the HCP Trustees (made up of the County Manager, and City Managers of Brisbane, Daly City and South San Francisco), providing oversight of the Habitat Manager, and interacting with the US Fish and Wildlife Service.

San Bruno Mountain Habitat Conservation Plan (HCP) Technical Advisory Committee (TAC)

The Technical Advisory Committee (TAC) was formed to provide assistance in the reporting of research, monitoring and habitat enhancement, and to report on the Plan’s scientific effectiveness and costs. The committee is currently chaired by the Director of San Mateo County Parks and participants include staff from the County (Plan Operator and Habitat Manager), weed control and restoration sub-contractors, and representatives of volunteer groups that are active on the Mountain, namely California Native Plant Society (CNPS) and San Bruno Mountain Watch. Formerly active organizations that participated on the TAC include Heart of the Mountain and the Friends of San Bruno Mountain. The TAC meets quarterly to review and recommend to the HCP Trustees annual and long-term management plans, review contractors proposed scopes of work, and initiate research to meet HCP goals.

San Bruno Mountain Habitat Conservation Plan (HCP) Trustees 

The San Bruno Mountain HCP Trustees oversee implementation of the San Bruno Mountain Habitat Conservation Plan. Trustees work in consultation with the Habitat Manager, the County of San Mateo, and the Technical Advisory Committee to determine and approve work programs to address needs identified through the Plan's monitoring program.
