Muralt Bluff Prairie occupies a long, sweeping ridge top in an area of older drift situated midway between the glaciated lands to the east and Driftless Area to the west. This high quality dry prairie contains numerous rare plants and animals. Dominant prairie grasses are little blue-stem, side-oats grama, Indian grass, and prairie drop-seed. Other grasses include prairie brome, purple love grass, and plains muhly. Outstanding spring displays of pasque flower, shooting-star, wood betony, and bird’s-foot violet occur in spring while asters, goldenrods, blazing stars, and gentians flower in fall. Several uncommon species are present including Hill’s thistle (Cirsium hillii), kittentails (Besseya bullii), and one-flowered broomrape (Orobanche uniflora), a parasitic plant. Animals of concern include the ottoe skipper (Hesperia ottoe) and grassland birds such as bobolink and grasshopper sparrow (Ammodramus savannarum), which are becoming more common as burning and brushing opens the area. The state-threatened Bell's vireo (Vireo bellii) nests here. Muralt Bluff Prairie is owned by The Prairie Enthusiasts and the DNR. It was designated a State Natural Area in 1977.
