The dunes are an important environment for a variety of plants and animals. The sand dunes themselves may appear lifeless, but they harbor three unique and sensitive species: the Saint Anthony evening primrose and two species of beetle. The dunes are ringed by thousands of acres of native grasses, junipers and sagebrush that provide habitat for sage-grouse and critical winter range for elk, mule deer and moose.
