Controlling Invasive Species Restores Ecology in Winegar Pond

Winegar Pond is a 120-acre coastal wetland sitting within the Green Bay West Shores State Wildlife Area. The wetland provides crucial habitat for breeding and migrating waterfowl, as well as spawning grounds for several native species of fish. The wetland is naturally connected to both the Peshtigo River and Lake Michigan, allowing migrating fish to access these spawning grounds. Unfortunately, this positioning also makes Winegar Pond susceptible to spawning populations of invasive common carp, which are enticed by the pond’s warm water and shallow depths. Spawning carp greatly disturb this ecosystem by uprooting native vegetation. The loss of native plant communities degrades water quality, decreases the availability of native fish habitat, and allows invasive plants like phragmites to colonize the area, further displacing native plants and reducing migratory bird nesting success. Thanks to funding provided by the Great Lakes Restoration Initiative, Ducks Unlimited has worked to stop the introduction of invasive species to restore habitat quality in Winegar Pond.
