Several of the spiders and insects are not known from any other site in Wisconsin. Of special interest are the black widow and several wolf spiders, five species of cicada, eight species of tiger beetles, and predatory wasps. The large pocket gopher population has created patches of open ground where short-lived plants grow. Nearly 40 species of annuals and biennials thrive here, a very high number for a prairie. Gopher tunnels are used by many of the reserve's 10 species of snakes, especially the bull snake.
Bird life includes large numbers of grasshopper and lark sparrows.
