Benthic Barrier Permit Regulations in Wisconsin

Benthic barriers, also known as bottom barriers, are a chemical-free solution for controlling invasive aquatic plants by blocking sunlight, which disrupts photosynthesis and suppresses plant growth. In Wisconsin, the use of benthic barriers is regulated to ensure compliance with state laws and environmental safety.

Do I Need a Permit to Use Benthic Barriers in Wisconsin?

Yes, to install benthic barriers for aquatic weed control in Wisconsin, you must obtain a permit from the Wisconsin Department of Natural Resources (DNR). The Wisconsin online permit process can be accessed through the DNR website by selecting “Physical Permitting Type.” You will also need to create a WAMS ID to complete the process.

What Invasive Aquatic Plants Are Common in Wisconsin?

Invasive species like Eurasian watermilfoil and curly-leaf pondweed pose serious threats to Wisconsin’s aquatic ecosystems. They can outcompete native plants, disrupt local habitats, and limit recreational use of waterways. Benthic barriers help manage these invasive species and protect native ecosystems.

What Are the Wisconsin DNR Restrictions for Aquatic Weed Control?

The Wisconsin DNR requires permits for various aquatic weed control methods, including:

• Chemical Treatments
• Biological Controls
• Physical Techniques (e.g., benthic barriers)
• Mechanical Removal

Permits are also required for activities involving wild rice, manual removal of plants over 30 feet in width along the shoreline, and mechanical harvesting.

How Do Benthic Barriers Affect the Environment in Wisconsin?

While benthic barriers are effective, it is crucial to assess their potential environmental impacts. Physical and biological control methods are generally recommended by the Wisconsin DNR over chemical treatments to minimize harm to non-target species and maintain water quality. Regular monitoring ensures effectiveness and minimizes adverse environmental effects.

Are There Local Regulations for Benthic Barrier Use in Wisconsin?

Local regulations may impose additional requirements or restrictions on benthic barriers and other aquatic weed control methods. Always check with your local municipality or aquatic plant management coordinator to ensure compliance with local guidelines.

What Steps Should I Take Before Using Benthic Barriers in Wisconsin?

• Review DNR Guidelines: Familiarize yourself with DNR’s requirements and obtain the necessary permits.
• Assess Environmental Impact: Include potential ecosystem effects and mitigation measures in your application.
• Consult Local Authorities: Confirm local regulations and permitting requirements for the specific waterbody.

Where Can I Find More Information on Aquatic Weed Control in Wisconsin?

• Wisconsin Department of Natural Resources (DNR): Offers resources on aquatic weed control regulations, permits, and shoreline management.
• Local Aquatic Plant Management Coordinators: Provide guidance on local regulations and permit processes.
