Geography
Country: United States
State: Indiana
Coordinate: 40° 45' N, 86° 4' W
Coordinate basis: based on nearby landmark

Habitat comments: "Approximately 88% of the area is under agricultural use, primarily for corn and soybeans" but all sites are in wetlands
treated as non-fragmentary because the wetland sites are interconnected through a drainage basin
