Canoe Landing Prairie is a Wisconsin Department of Natural Resources-designated State Natural Area featuring a diverse Hill's oak barrens and prairie community growing on the gently rolling, sandy uplands near the Eau Claire River. Plant composition includes the following species: Big bluestem, side-oats grama, butterfly weed, blue toadflax, and birdsfoot violet. Wild lupine is also found in the prairie, and supports a population of the karner blue butterfly, an endangered species whose caterpillars feed solely on wild lupine.
