The Swanson Lakes Unit is comprised of channeled scabland, featuring plateaus, buttes, numerous pothole lakes, a handful of rim rock lakes, and one intermittent stream. This large diverse unit supports a mix of species, including mule deer, upland game birds, raptors, songbirds, and several reptiles and amphibians. The unit lies within one of the last remaining large areas of shrubsteppe habitat in the Columbia Plateau and is a priority for protection of imperiled species, including the Columbian sharp-tailed grouse.
