Wetland Research Sites

Heim Road Wetland: Heim Road Wetland, located along Heim Road in Warrick County, is an example of a created wetland. To mitigate the loss of wetlands when the road was widened and bridgework done, a wetland was created adjacent to some naturally occurring bottomland forest along Pigeon Creek. The wetland was created in the mid 1990's and planted with several tree species and herbaceous plants. Additionally, several volunteer species have become established.

Howell Wetlands: Howell wetlands features 35 acres of wetland habitat that is a remnant of an old channel of the Ohio River. Despite its location in the middle of Evansville, it is comprised of wetland habitats such as marshes, bottomland hardwood forests, a bald cypress slough, and oxbow lake, and upland meadows. This diverse wetland area is home to a variety of wildlife and plants.

Wesselman Woods: Wesselman Woods is an Indiana State Nature Preserve and National Natural Landmark consisting of 240 acres all within the city limits of Evansville, Indiana. It is an old growth bottomland hardwood forest wetland that provides crucial habitat for a variety of wildlife and boasts a wide diversity of trees (the oldest over 400 years old), shrubs and wildflowers.

Bluegrass Fish and Wildlife Area: The Bluegrass Fish and Wildlife Area is named after Blue Grass Creek which runs along the eastern edge of the property. The Bluegrass FWA, formerly called Ayrshire property, is a reclaimed strip-mine area that comprises about 2500 acres of grasslands, scrub-shrub habitat, marshes, wet meadows, and of course strip pits (600 acres).

Eagle Slough: Eagle Slough was established in 2008 as the result of the combined efforts of four conservation organizations; the Vanderburgh County Soil and Water Conservation District, Four Rivers Resource Conservation and Development Area, Wesselman Nature Society, and The Nature Conservancy. This new nature area will be used for educational purposes and to promote conservation. This wetland area is a mostly bottomland hardwood forest with some bald cypress habitat also present. The Nature Conservancy is currently working on an inventory of plants and the Audubon Society is conducting a survey of birds that use the slough.

Lost Hill Wetland: Lost Hill Wetland is part of a wetland complex associated with Pigeon Creek in Warrick County. It is mostly bottomland hardwoods, with some open marsh habitat. It is part of the Marchand Wildlife Area managed by the State of Indiana. The Lost Hill wetland offers a diverse plant and animal community with swamp rabbits, copperbelly water snakes, a heron rookery and numerous wetland plants available. When construction of the new Interstate 69 begins, approximately 4-6 acres of this wetland may be impacted.

Patoka River National Wildlife Refuge: Patoka River National Wildlife Refuge and Management Area is located in southwest Indiana. It was established in 1994 as the 502nd national wildlife refuge and currently contains about 5,587 acres.
