Scientific Studies
There have been many scientific studies of the geological and ecological resources on The Irvine Ranch over the last few decades. But the comprehensive review and evaluation leading to the Natural Landmark designation is the most rigorous, objective and independent scientific study ever conducted on the land. Findings of the seven accomplished scientists who participated in this review both confirm and reinforce previous evaluations recognizing the importance of this open space.
The process for Landmark evaluation included a detailed application prepared by LSA Associates, Inc. in Irvine, California. The exhaustive review included onsite evaluations conducted by independent biologists and geologists selected by the National Park Service. These experts produced an extensive report that was then peer-reviewed by seven other independent scientists. Based on these evaluations and the recommendations of the Science Advisory Committee of the National Park Service, the National Park Service Advisory Board, and the National Park Service director, the Secretary of the Interior designated the Irvine Ranch National Natural Landmark in 2006. A similar objective review led to the designation as a California Natural Landmark on Earth Day 2008 by the California State Parks director.
