Acquisition of the Quail Ranch Complex would resolve a key conservation gap between several large habitat preserves, creating improved resource management and protection of critical wildlife. The property is important habitat for the federally-endangered Stephen’s kangaroo rat, least Bell’s vireo, tricolored blackbird, spreading navarretia and San Jacinto crownscale.

Completion of the Irvine-Laguna Wildlife Corridor will prevent 22,000 acres of natural lands from becoming a genetic island of habitat, threatening extinction of many species and subspecies. Species protected with this corridor include California gnatcatcher, Least Bell’s vireo, coastal cactus wren, Pacific pocket mouse, bobcats, an occasional mountain lion, and multiple plants.

State Parks for 45 years. These lands are also part of a larger effort to connect 19,000 acres of protected wildlands to the 4,000-acre Prado Basin wetlands. The property includes habitat for cactus wrens, cougar, California gnatcatcher, and various raptors. Habitat types include grasslands, chaparral, coastal sage scrub, and walnut and oak woodlands. It also has freshwater and emergent wetlands.
