Mammals of the tallgrass prairie area include 25 species. Free-roaming bison, along with Great Plains wolf, swift fox, pronghorn antelope, and grizzly bear are no longer found in Minnesota or Iowa. Black bear and elk can still be found in Minnesota; however, they no longer occupy their prairie niche. The grey wolf has filled the niche vacated by the Great Plains wolf in the Aspen Parklands area of Minnesota but on a limited basis. Mammals that are commonly seen in the area of the refuge include beaver, muskrat, white-tailed deer, red fox, coyote, raccoon, and striped skunk.

Thirty-three species of reptiles and amphibians are found in the Minnesota and Iowa portions of the northern tallgrass prairie. The precise number of insect species which live in, breed in, or visit the tallgrass prairie is unknown, but estimated in the thousands. Their density in one square meter of Iowa tallgrass prairie was found to be 1,850 species. In the average prairie there are more species of invertebrates than of plants and vertebrate animals combined.
