Resource Management

By Sharon ArnoldThe U.S. Fish and Wildlife Service's mission is working with others to conserve, protect and enhance fish, wildlife, and plants and their habitats for the continuing benefit of the American people. We are the only agency of the U.S. Government with that primary mission.

Cross Creeks NWR consists of rich bottomlands surrounded by rolling, heavily forested hills and rocky, limestone bluffs. Deciduous woodlands characterize the surrounding hillsides, while the bottomlands primarily consist of open water impoundments and cultivated fields. The types of habitats found on the refuge are cropland, moist-soil vegetation, forested uplands, isolated bottomland hardwoods, and open water habitats.

The diversity of aquatic and terrestrial habitats enables many wildlife species to make the refuge their home either during the entire year, during the winter months as many waterfowl do, or during temporary stopovers as do some migratory songbirds.

During the spring and summer,water is removed from the shallows of several impoundments to allow for the germination of natural wetland plants. After the plants have matured and produced an abundance of seeds, the impoundments are flooded. Waterfowl and other marsh birds feast upon these natural seed sources. Drawing the water down in the moist soil areas also produce mud-flats that nourish shorebirds during their spring and fall migrations. 

Select refuge lands are offered to local farmers under the cooperative farming program. In exchange for a share of the crop, local farmers cultivate and plant the refuge’s fertile lands to produce corn, milo, and winter wheat for waterfowl. The refuge’s share is left unharvested in the field. Flooded agricultural fields of unharvested crops draw ducks and geese onto the refuge where they are able to feed and rest. Healthy, well-nourished ducks and geese depart the refuge in early spring.

Invasive plant species clog pipes, inhibit water flow, and out-compete native plants that provide beneficial food and cover. Thus, invasive species present a significant obstacle to resource management. Invasive or undesirable species occurring at Cross Creeks NWR include alligatorweed, parrotfeather, spatterdock, kudzu, privet, castor bean, Apple of Peru and Japanese stilt grass. Through impeding water management, invasive species contribute to the less than maximum productivity of the agricultural fields for waterfowl food that requires flooding. Spatterdock exists in the ponds, and alligatorweed out-competes native wetland species. Japanese stilt grass impacts natural regeneration, causes tree stress, and affects nesting habitat.
