There are several native plant communities found on Belwin's property including dry sand-gravel prairie, oak forest and three types of wetlands, including floodplain forest, seepage meadow and rich fen. Five animal species and three plant species, considered rare by the Department of Natural Resources have been documented on Belwin property.
