Since 2005, Irvine Ranch Conservancy has ensured the protection, restoration, and enhancement of the Irvine Ranch Natural Landmarks — a collection of 25 distinct biological and geological treasures on more than 40,000 acres of Southern California’s illustrious urban wildlands. We actively manage these Landmarks and the vast acreage of publicly owned land that encompasses them in partnership with the Cities of Irvine and Newport Beach, Orange County Parks, and numerous other community partners.
