Cotton Creek Marsh contains 247 acres of high quality wetland on the Fox River floodplain in the Northeastern Morainal Natural Division. Besides the marsh, the other natural communities present at Cotton Creek are sedge meadow, low gradient creek, wet prairie, fen and successional fields. The marsh constitutes the majority of the area and is the most attractive feature. Sedges, cattails, bulrushes, common burreed, sweet flag, water knotweed, and common arrowhead are dominant plants in this community. The marsh grades into sedge meadow where vegetation from both communities overlap. The sedge meadow is dominated by tussock sedge and blue-joint grass. Sandhill cranes regularly nest in this preserve.
