Biological Diversity
The Spring Mountains are a sky island ecosystem. With an area of about 860 square miles (2,200 km2), and a vertical range of nearly 2 miles (3.2 km), the mountains encompass a wide variety of habitats, and the biological diversity is probably greater than anywhere else in Nevada. 37 species of trees are known (more than any other Nevadan range), and 600 species of vascular plants have been reported from the Red Rock Canyon National Conservation Area alone.
The bases of the mountains are part of the Mojave Zone dominated by creosote bush and white bursage, then rising to a Blackbrush Zone, followed by a Pygmy Conifer Zone with juniper, pinyon pine and mountain-mahogany, and topped by a montane zone with many species of conifers around Mt. Charleston and its connecting ridges.

Famous quotes containing the words biological and/or diversity:
“It is not the literal past that rules us, save, possibly, in a biological sense. It is images of the past.... Each new historical era mirrors itself in the picture and active mythology of its past or of a past borrowed from other cultures. It tests its sense of identity, of regress or new achievement against that past.”
—George Steiner (b. 1929)
“... city areas with flourishing diversity sprout strange and unpredictable uses and peculiar scenes. But this is not a drawback of diversity. This is the point ... of it.”
—Jane Jacobs (b. 1916)
