Vieira Ranch Conservation Bank

Wildlands is working in collaboration with the U.S. Fish and Wildlife Service (USFWS) and the California Department of Fish and Wildlife (CDFW) to establish the proposed Vieira Ranch Conservation Bank in Alameda County. The new bank would permanently protect habitat for the following special-status species: federally and state threatened California tiger salamander (Ambystoma californiense), federally threatened California red-legged frog (Rana draytonii), federally endangered and state threatened San Joaquin kit fox (Vulpes macrotis mutica), and state species of special concern burrowing owl (Athene cunicularia).

The Bank is proposed on a portion of a 3,500-acre cattle ranch (Vieira Ranch) located in unincorporated Alameda County. The Bank property is well-suited for conservation of CTS and CRLF in part because of its density of high-quality breeding habitat. Expansive grasslands within the surrounding property and landscape provide important movement corridors for species such as SJKF and support several special-status birds including tricolored blackbird, BUOW, and golden eagle as evidenced by the large number of occurrences in the vicinity and observations during surveys.

Service Area


The proposed service area boundaries are in development. The Covered Species service areas will be based on analyses of species’ federal recovery units and biological attributes; the Bank’s contribution to Covered Species and other special-status species habitat protection; local, regional, and federal planning efforts and recovery unit boundaries; and the area necessary to support a conservation bank of this size.
