The Dublin Ranch Preserve protects approximately 717 acres as part of the Dublin Ranch development which is under the greater Eastern Dublin Specific Plan. The Preserve consists of three units including the Northern Drainage Conservation Area (267 acres), Tassajara Creek Conservation Area (54 acres) and the Lin Livermore Conservation Area (397 acres).

The Lin Livermore Conservation Area is located in unincorporated Alameda County, north of Livermore, CA. The Preserve is privately owned.
CNLM holds a conservation easement as well as a long-term agreement to protect the Preserve in perpetuity.
The Preserve consists primarily of annual grassland typical of the coast range. Wetlands and other waters are present on site including seasonal wetlands, riparian habitat, stock ponds, and perennial and ephemeral streams.The Preserve was established to permanently protect the California red-legged frog (Rana draytonii) and to create and preserve the seasonal wetland/aquatic habitat.
The Preserve provides high quality habitat for the federally listed threatened California Red-legged frog, the federal and state-threatened California tiger salamander (Ambystoma californiense), and the state and federal species of concern, burrowing owl (Athene cunicularia). The Preserve is also managed for San Joaquin kit fox (Vulpes macrotis mutica) habitat, a federally endangered and state-threatened species, and protects nesting habitat for golden eagle (Aquila chrysaetos), a state species of special concern.
CNLM holds a conservation easement and is responsible for long-term management of the Preserve. The primary goals for management of the Preserve are to provide permanent protection and management of seasonal wetland and riparian habitats and the sensitive species including the California Red-legged Frog, the California Tiger Salamander, and the golden eagle.
Cattle grazing is used to maintain short grass habitats that are essential for these species.The purpose of the conservation easements is to help ensure that the properties will be retained in perpetuity in open space condition and to prevent any use of the properties that will impair or interfere with the conservation values of the Preserve.
Due to the vulnerability of the species and habitats that exist on this Preserve, it is not open to the public.
