These lands are enrolled in the Central and Coastal Subregion NCCP program and span nearly 20,000 acres of natural forest, making it the largest remaining open coastal space between Los Angeles and San Diego. The Reserve is home to a variety of rare species, including the endangered California gnatcatcher, the threatened coastal California gnatcatcher, and the endangered California red-legged frog. Other rare species found in the Reserve include the San Diego fairy shrimp, the San Diego button celery, and the San Diego thornmint.
The Reserve also provides habitat for a variety of birds, including the endangered least Bell's vireo and the threatened southwestern willow flycatcher. The Reserve is managed by the Irvine Ranch Conservancy (IRC), which works to protect and restore native habitats. The IRC has implemented a number of conservation measures to protect rare species living in the Reserve.
