Key Habitats:  Annual grasslands; Wetlands (natural ponds and freshwater springs and seeps, Wetland basins, Perennial & ephemeral streams); Riparian woodlands.

Species of Special Interest to CNLM: San Joquin Kit FoxCalifornia tiger salamander and California red-legged frog (US Fish & Wildlife Service).

Conservation Significance

The Preserve consists of preserved, created and restored features, including stock ponds, grassland, riparian woodland and seasonal wetlands.  The Preserve was established to provide habitat for the Federally Endangered San Joaquin kit fox (Vulpes macrotis mutica), Federally Threatened California tiger salamander (Ambystoma californiense) and the Federally Threatened California red-legged frog (Rana aurora).  In addition, burrowing owl, American badger, golden eagle, northern harrier, prairie falcon, loggerhead shrike, and tri-colored blackbird are known to inhabit the preserve.

Our Work

Our goal for the Windemere Ranch Preserve is to protect the habitats and the species that depend upon the Preserve for survival.  We use a variety of strategies to accomplish our goals, which include cattle grazing in an effort to maintain short grassland habitats essential for the California red-legged frog and California tiger salamander.

Public Access

Because of the vulnerability of the species and habitats that exist on this preserve, it is not open to the public. However, the East Bay Regional Parks Districts (EBRPD) has a network of public trails throughout the region. Boundaries of this system, along with Windemere Ranch Preserve, are clearly marked, providing information on accepted and prohibited activities and all public use restrictions. This trail system is owned and maintained by the City of San Ramon.
