Invasive species treatments were scheduled to get underway in Kewaunee County on Monday, but Bay-Lake Regional Planning Commission reported a lot of gaps in permissions from property owners along the Ahnapee and Kewaunee rivers.

“We want to be able to treat the entirety of both corridors,” said Angela Kowalzek-Adams, natural resources planner with Bay-Lake. “These permission forms are needed for all lands along the river corridors in order to be able to address phragmites and Japanese knotweed where the contractors find it.”

Property owners’ permission to treat invasive plants along their waterfront property is needed in order to stand a chance of eradicating phragmites and Japanese knotweed from the county, Kowalzek-Adams said.

Permission slips are needed by the end of the week to ensure a successful program, she said.

Property owners with questions can contact Kowalzek-Adams at or 920-448-2820, ext. 106. Kate Hau of the Kewaunee County Land & Water Conservation Department said Tuesday she is also willing to answer questions at 920-845-9747 or
