SC Holdings-Wilsonville Facility

About the Program
Waste Management’s SC Holdings-Wilsonville Facility is located in Wilsonville, IL which lies in Macoupin County near the western border of the state. Previously, the site was an underground coal mine and a landfill. The Wilsonville team currently manages 75 acres of grassland habitat for the benefit of a wide variety of wildlife, as well as 25 acres of wetlands to benefit species such as Cope’s tree frogs and garter snakes.

Practices and Impacts

• The team maintains the site through rotational mowing to control woody species and non-native, invasive species. Several times each year the team monitors the grassland to determine the health of the habitat, the need for mowing, the presence of invasive species and use by wildlife. 
• The Wilsonville Facility 25-acre wetland project also began in 2008 and is managed to provide quality habitat for a wide variety of birds, reptiles, amphibians, insects, mammals and fish. The Wilsonville team monitors the wetland vegetation and water levels several times each year to ensure the wetland is protected against erosion and for the presence of invasive species.
• In May of 2017, the Wilsonville team installed frog tubes and cover boards to provide shelter for amphibians and reptiles, such as Cope’s tree frogs and garter snakes. An additional five tubes were added to the habitat in 2019. Several times per year, the Wilsonville team monitors the tubes and boards for use by wildlife.
• In May 2017, the team installed a purple martin nest box and continue to monitor and maintain the nest box through annual cleaning.
• In April 2015, the team installed and continues to monitor bat boxes, specifically targeting the little brown bat in addition to other native bat species.
