Management of Non-Native Hybrid Cattails
Voyageurs National Park » Management of Non-Native Hybrid Cattails » Document List
Hybrid cattail invasions are having the largest impact on the shoreline ecosystems, creating large dense monocultures. These monocultures can grow to very large sizes creating mats that cover entire bays. This is causing a variety of problems related to the natural resources and the visitor's use of the park. These issues are:
- The hybrid cattails are invasive and are spreading to new locations.
- Floating mats break off in windy conditions creating navigation hazards and facilitate the spread of cattails.
- The invasive nature of hybrid cattails leads to habitat degradation.
• Muskrat and other wildlife habitat is diminished.
• Fish spawning areas are reduced.
• Vegetation biodiversity is reduced.
- The visitor experience is hampered. Canoeing, fishing, and wildlife viewing opportunities are reduced.
- The cattails can choke out shorelines and boat docking areas creating the need for periodic maintenance to remove the vegetation.
To address these issues, Voyageurs National Park has prepared an Environmental Assessment (EA) for the removal of invasive hybrid cattail and the subsequent restoration of native marsh plant communities. The EA explores alternatives for treatment or removal of cattails and restoration of native plants.
