Within Illinois, wetland conversion and drainage has been especially extensive where an estimated 90% of original wetland area has been lost (Suloway and Hubbell 1994). Therefore, protection of remaining wetlands and creation of functional replacement wetlands to mitigate unavoidable losses is a high priority within the state. Although the National Research Council (2001) report on compensating for wetland losses identified seasonal wetlands as one of the most difficult wetland types to create, wetland creation is listed as a Priority Action Campaign within the Illinois Wildlife Action Plan (IDNR 2005). In southeastern Illinois (Natural Heritage Districts 14, 21, and 22) more than 250 seasonal wetlands have been created at 14 different IDNR managed properties over the last decade (T. Esker and R. Jansen, IDNR District Heritage Biologists, pers. comm.). However, follow up sampling to document the success or failure of these created wetlands is lacking (T. Esker and R. Jansen pers. comm.).
