Reversing Phragmites spread

From 2017-2019, our research documented the distribution of Phragmites populations in Minnesota. Many populations are producing viable seed and so have high capacity for further spread. However, these numerous populations currently add up to an area of only approximately 50 acres. In light of these findings, a coordinated, statewide control effort with the aim of eliminating all established populations is still feasible, if pursued without delay.

Invasive Phragmites has the capacity to quickly spread and overtake areas; partial or uncoordinated responses are unlikely to be beneficial or cost-effective. We have developed an assessment of capacity and possible strategies to support a strategic, coordinated response to invasive Phragmites in Minnesota.

Reversing the spread of invasive Phragmites would yield significant benefits to Minnesota’s natural resources. The effectiveness of a strategic, concerted response to invasive Phragmites will hinge on: Phragmites report

  • Strong partner engagement and effort
  • Sound control implementation
  • Sufficient funding and policy

The assessment above provides a detailed explanation of issues that would need to be addressed as well as possible strategies and estimated costs. We strongly encourage anyone coordinating invasive Phragmites response efforts to review the assessment.
