      Amboy Marsh was purchased by the Illinois Audubon Society in 2012. This acquisition provides for permanent protection of a rare and fragile portion of the Green River Lowlands section of the Grand Prairie Division.

      Located in southeastern Lee County, the 302-acre wetland complex is interspersed with black oak sand savannas, sedge meadows and dry sand prairie. Diverse habitat provides homes for a variety of native flora and fauna.

      By definition Amboy Marsh Nature Preserve is a watery place. Several springs and seeps emerge from the side of sand dunes; characteristic marshes and wetlands here have always been a seasonal phenomenon, a blessing for amphibians that require fishless ponds for successful breeding.
