Some 12,000 years ago, northeastern Ohio was occupied by a large glacial lake, which deposited a thick layer of silt and clay ranging in depth from 5 to 50 feet. Watertight, these clay soils resulted in the formation of swamp forest, marshes, sphagnum bogs and sedge meadows.
Today, these wetlands are part of the Grand River Lowlands. A major tributary to Lake Erie, the Grand River – a state-designated “Wild and Scenic River” – and its surrounding wetlands are critical in the protection of this globally important freshwater resource.
At 1,015 acres, The Nature Conservancy’s Morgan Swamp Preserve is one of the largest privately protected wetlands in Ohio and plays a key role in keeping the freshwater resources of northeastern Ohio healthy.
Morgan Swamp and the surrounding area is a 2,000-acre remnant of a five-square-mile swamp that existed at the time of European settlement. By the beginning of 20th century, the entire region had been subjected to logging, draining, peat fires and farming.
Relatively undisturbed for nearly 100 years, Morgan Swamp is recovering from these impacts and is now dynamic and self-sustaining. The preserve harbors an array of rare species, many of which are associated with boreal habitats and are near the southern edge of their ranges in North America. A faunal survey of the preserve has revealed 108 bird species, 24 fishes, 26 reptiles, and 24 mammals.
The greatest threats to Morgan Swamp Preserve are the destruction of adjacent wetlands, logging within the Grand River floodplain and upland forest communities, and invasive species. The Conservancy has been working to combat these threats through restoration, land acquisition, and education efforts.
