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

Our current invasive species management project is an EPA GLRI funded project to manage Phragmites, Japanese knotweed, and Wild parsnip in Kewaunee County. This project will include two season of herbicide treatment on public and private land in 2018 and 2019. 

2019 treatments will start early September. Regular updates on treatment locations will be provided on our Invasive Treatment Hotline at (920) 430-0220.

With funding from the EPA Great Lakes Restoration Initiative (GLRI), the Bay-Lake RPC will treat at least 1,000 acres of invasive Phragmites, Wild parsnip, and Japanese knotweed in Kewaunee County in 2018 and 2019 and help the County to establish a permanent management strategy.

The invasive species treatment are being conducted under Chemical Aquatic Plant Control Permit Number: NE-2019-31-5262 from the Wisconsin Department of Natural Resources.
