Article abstract: Vernal pool habitat in southern California, and specifically southern San Diego County, has been greatly diminished as a result of extensive development throughout the region. The value and function of remaining vernal pool habitat continue to be degraded by development-related disturbances such as trespassing, grazing, and invasion of nonnative species. As a result, the sensitive species that are supported by vernal pool habitat are also at risk. To halt the decline and stabilize the vernal pools in San Diego County, and restore habitat function and sensitive species populations, restoration and management actions are necessary. The City of San Diego (City), in cooperation with other coordinating agencies such as the County of San Diego (County), San Diego Association of Governments (SANDAG), U.S. Fish and Wildlife Service (USFWS), California Department of Fish and Game (CDFG), and California Energy Commission (CEC), obtained grant funding to protect, restore, and manage portions of the remaining vernal pool habitat in southern San Diego County. AECOM (formerly EDAW, Inc.) was retained by the City to conduct a comprehensive assessment of existing vernal pool sites within the jurisdiction of the City and County, develop and prioritize recommendations for restoration and management of those sites, and implement restoration and management of the sites. This report summarizes the results of implementation of the restoration and management recommendation actions at five key vernal pool sites in the County.
