Industrialization and urbanization have reduced wetlands and wetlands in the Calmette region from tens of thousands of interconnected acres to isolated fragments. Conservation activists are working to restore some of the region’s hydrology, but nature needs the help of the plumbing sector.

In the Lake Powderhorn Forest Reserve, construction of an artificial water management structure is underway, reconnecting the Powderhorn Wetland to Lake Wolf and eventually Lake Michigan, in the process of healthier habitat for wildlife. Rebuild the ground.

The project was announced in early 2020 As a joint effort of the Great Lakes of Audubon, the Cook County Forest Reserve, the Great Lakes Commission, and the US National Oceanic and Atmospheric Administration. Preliminary engineering research has been completed and restoration is moving to the next stage.

Healthy wetlands perform many important services within the ecosystem, including storing large amounts of rainwater, filtering pollutants, and supporting diverse wildlife. Powderhorn wetlands have long been inoperable and their water is stagnant at high levels, such as ponds and pools, rather than seasonally declining and rising. As a result, invasive species choke the natives and Swamp birds then struggled To survive in a difficult habitat.

The water management structure allows forest protection staff to control the water level of the powder horn. By recreating the rising and falling nature that was lacking, native wetland plants should be able to regain their foothold and the swamp bird revival should continue. Bird populations such as Pied-billed Turtle, Least Bittern, and common gallinules are monitored and measurable increases are important benchmarks for project success.

Water control structures have been deployed to Indian Ridge Marsh, Big Marsh, and Eggers Gloves as well. Calmet Wetland Conservation Action Plan..
