Bio-Geographic Crossroads

One of the Reserve's most notable qualities is its large degree of biological diversity concentrated in a relatively small area. Located in the Northern Basin and Range province, the habitat of the Reserve supports a large variety of mammals, birds, reptiles, and invertebrates.

At first glance, City of Rocks would appear to be a tough place for wildlife to survive. Diverse habitats at various elevations lead to an area bursting with wildlife. It goes without saying that animals at City of Rocks are equipped with special adaptations to survive extreme conditions. During summer, most fauna are active at night, thereby escaping the often hot, dry days. Winter forces wildlife to migrate to better environments or to hibernate. To see as many different types as possible, include the following habitats in your search: pinyon-juniper-mahogany forest, aspen-riparian areas, sagebrush flats, and spruce-firpine forest above 7,000 feet.
