Invasive Species Management

The Bay-Lake RPC undertakes local and regional project to manage or mitigate invasive species such as the Emerald Ash Borer (EAB), Phragmites, Japanese knotweed, and Wild parsnip. Our projects range from municipal EAB mitigation plans to countywide treatment of multiple invasive species.

Past projects include: City of Algoma, Wisconsin Emerald Ash Borer Readiness Plan, November 2010; Kewaunee County, Wisconsin Emerald Ash Borer Readiness Plan, October 2010; and two-year management of Phragmites in Brown County along the lower bay, Fox River, East River, Duck Creek, and Baird Creek.

Kewaunee County Invasive Species Management Project

In 2017, Bay-Lake RPC was awarded funding through an EPA GLRI grant to treat up to 1,000 acres of Phragmites, Japanese knotweed, and Wild Parsnip within Kewaunee County. Over the years of 2018, 2019 and 2020, the Commission was able to successfully treat 1,002 acres of invasive species within the County. These treatments occured within rights-ofway, along river corridors and over the properties of 470 individual landowners!
