The Limberlost Swamp in the eastern part of the present-day U.S. state of Indiana was a large, nationally known wetlands region with streams that flowed into the Wabash River. It originally covered 13,000 acres (53 km2) of present-day Adams and Jay counties. Parts of it were known as the Loblolly Marsh, based on a word by local Miami Native Americans for the sulphur smell of the marsh gas. The wetlands had mixed vegetation and supported a rich biodiversity, significant for local and migrating birds and insects, as well as other animals and life.
European Americans drained the Limberlost for agricultural development early in the 20th century, destroying the rich habitat. Since 1997, parts of it have been restored. Observers have documented a return of insects, birds, and wildlife of all sorts to the restored area of wetlands. Approximately 1,500 acres (6.1 km2) had been restored as of 2015. Several groups supported purchase of lands for what is now known as the Loblolly Marsh Nature Preserve, which was turned over to the state and is held by the Indiana Department of Natural Resources.
