The Irvine Ranch Open Space Legacy
Beautiful, vast and remarkably diverse, the natural open space, parks and trails throughout The Irvine Ranch® comprise more than 50,000 acres - more than half of the historic 93,000-acre ranch. A majority of the lands have been designated a National Natural Landmark (NNL) by the U.S. Department of the Interior based upon a rigorous scientific evaluation of its environmental value. In addition, they have been designated the first-ever California Natural Landmark (CNL) under a new state program.
The Irvine Ranch's permanently protected open space is home to hundreds of species of native plants and animals and offers every form of public recreation imaginable. It is a remarkable legacy of foresight, and reflects the fact that protecting precious natural resources has always received the same level of thoughtful planning as has creation of the acclaimed master-planned communities on the Ranch.
