ABSTRACT: The wetlands in southeastern Missouri have a long history of alteration. Since the 1950’s, Duck Creek Conservation Area has been managed by the Missouri Department of Conservation to provide wetland habitat for waterfowl and other wetland dependent species within this altered landscape. Over time our philosophy of wetland management, the implications of infrastructure design, and the interaction of natural features has evolved. Based on a hydrogeomorphic assessment of the larger Mingo basin surrounding Duck Creek we identified the four following objectives to renovate the aging wetland management area: 1) restore natural water flow patterns where possible, 2) mimic natural water regimes, 3) restore natural vegetation communities, and 4) accommodate public uses that are consistent with resource objectives. A multi-disciplined team of biologists and engineers used a basin wide digital elevation model, aerial photos, and field observations to examine the landscape features and identify opportunities to restore wetland system processes to achieve these objectives. These steps have reduced several chronic management challenges, increased the wetland habitat diversity, and enhanced the wetland function of the area. Following construction, we've been able to document the responses of both aquatic and avian communities through the annual cycle and periods of flood connectivity. The collaborative approach and incorporation of system processes into the renovation have benefited Duck Creek Conservation Area.
