Delair Division Habitat Restoration and Enhancement Project

Rock Island District

Pool 24, Upper Mississippi River, Miles 278 - 282,  Pike County, Illinois, Congressional District: IL - 18




The Delair Division provides one of the few tracts of natural floodplain vegetation that exists within the 123,000 acres of agricultural lands that make up the Sny Island Levee District.  Hundreds of acres of former agricultural lands have already been restored to wetland, forest, and grassland on Delair, but some resource issues remain.

The current forest acreage on the Division is interspersed with small crop fields and is heavily fragmented.  Fragmented forests have reduced value for many species of nesting neotropical migrant songbirds.

Wetland management at the Division is still restricted by inadequate water control structures and water delivery systems.  Also, timely management of wetlands that do not receive seep water is limited, but would be enhanced by the addition of two or three shallow groundwater wells.
