Since 1998, ABF has been able to acquire several major ranch properties that Park planners long ago had hoped would become part of Anza-Borrego Desert State Park. These properties represent land values in excess of $23 million - a phenomenal commitment by nonprofits, government agencies and individuals intent on preserving California’s wild lands.

Sentenac Canyon and Cienega is a rare desert wetland located at Scissors Crossing – the junction of highways S2 and 78. Funding for the 1,723 acres was provided by State and Federal agencies, regional foundations, and individual donors.
Lucky 5 Ranch In 2001, the purchase of 2,675-acre Lucky 5 Ranch created a wildlife corridor between Anza-Borrego Desert State Park and Cuyamaca Rancho State Park, a mountain habitat. Funding was sparked by a $2 million anonymous donation and State and Federal funds.

Mason Valley In 2002, 842 acres of Mason Valley became part of Anza-Borrego Desert State Park. Major funding was provided by the National Fish and Wildlife Foundation, Proposition 40, foundation grants, and individual donations.
Vallecito Ranch The historic 3,339-acre Vallecito Ranch, a critical habitat for over 50 rare and endangered species of plants and animals, was purchased in 2004. Funds were provided through Resources Legacy Fund Foundation’s Preserving Wild California program, The Nature Conservancy, and State and Federal programs.
Horse Canyon In 2004, ABF and the Native American Land Conservancy jointly acquired and transferred to the Park 1,298 acres of Horse Canyon. The canyon, a tributary of Coyote Canyon, contains important archaeological sites and is part of bighorn sheep habitat.
Tulloch Ranch In 2005, another wildlife linkage was made with Cuyamaca Rancho State Park when the 2,080-acre Tulloch Ranch was added to Anza-Borrego Desert State Park. Funding was provided by State and Federal programs, and a private foundation grant.
