Description: 
Mehl's Bluff occurs on a deeply dissected bluff bordering the Mackinaw River in the Grand Prairie Section of the Grand Prairie Natural Division. This diverse site contains upland forest, floodplain forest, seep and creek communities. High southwest facing bluff exposures support plant species typical of savanna and hill prairie remnants. Seep springs occur in a steep ravine that bisects the preserve. The preserve provides habitat for a great diversity of native plants, including the heart-leaved plantain. As part of a much larger forest complex, Mehl's Bluff provides habitat for numerous area-sensitive, forest interior birds, including the Acadian flycatcher, woodthrush, scarlet tanager, red-eyed vireo and veery. Unusual patterned ground features occur in the floodplain near the mouth of a creek that drains into the Mackinaw River. These ground features are polygonal patterns that formed during mechanical weathering processes in very old soil.
