Limestone Canyon, part of the Irvine Ranch Open Space, is located on the historic Irvine Ranch. Because of its rare biological and geological features the land is designated as a National Natural Landmark by the U.S. Department of Interior and is the first California Natural Landmark. Limestone Canyon, like all of Orange County, is in a Mediterranean Climate Zone which only occurs in five places in the world. Mediterranean Climate Zones occupy less than 2% of the Earth’s surface, but host 20% of the plant and animal species known to exist in the world.
