Lake County Forest Preserve District controlled invasive species and improved hydrology at Spring Bluff, a 234-acre Illinois Nature Preserve, which represented Phase II of a larger project. The preserve was threatened by several invasive species such as cattails, common reed, and reed canary grass. In addition, a culvert was restricting flow and causing adverse effects on the hydroperiod of some of the preserve’s wetlands. In 2007, the District began invasive species control across 88 acres of wetlands, and Phase II of the project continued and expanded these efforts. For this project, the culvert was removed and 112 acres of the wetland were restored. This included the addition of 2 water control structures. Invasive species control involved selective herbicide application and prescribed burning.
