Draft Phragmites and Japanese Knotweed Management Plan

The Ozaukee Washington Land Trust, Inc. (OWLT) is partnering with the Southeastern Wisconsin Invasive Species Consortium, Inc. (SEWISC) and Stantec Consulting Services, Inc. (Stantec) to draft a management plan detailing proposed treatment strategies to control non-native invasive species along the Lake Michigan shoreline, connected wetlands and riparian area and select inland areas within Sheboygan and Ozaukee Counties. OWLT intends to apply for Wisconsin Department of Natural Resources (WDNR) Aquatic Invasive Species (AIS) Control Grant funding to fulfill the goals and objective set forth in the plan.

 Phragmites and Japanese knotweed are particularly troublesome in that they form dense stands that crowd out native vegetation, resulting in reduced plant species diversity and wildlife habitat quality. Dense stands are inhospitable to native birds, have lowered invertebrate densities, reduce the ecological value of shorelines and can also impact the hydrologic regime of wetlands by increasing evaporation and trapping sediment.

 Proposed activities include:

  • Mapping showing the distribution and location of non-native Phragmites and Japanese knotweed
  • Educating landowners about Phragmites, Japanese knotweed and other aquatic invasive plants and why treatment is important
  • Soliciting landowner permission to treat infestations on their properties
  • Coordinating and prioritizing treatment
  • Increasing capacity of citizens to conduct subsequent maintenance and monitoring of infestations on their properties
  • Promoting restoration of sustainable, native communities

The draft management plan is open for public notice until November 25, 2016.
