Environmental and Economic Concerns

  • Sprawling grass up to 15 feet long that forms dense tufts on shorelines
  • Provides little wildlife value and crowds out native plants

  • Fills ditches and shallow canals, impeding water movement
  • Mats can break loose from shorelines forming floating islands

  • Chemical: Glyphosate, imazapyr;
  • Mechanical: Mowing; harvest or shred floating mats
  • Physical: Drawdown, desiccation, and burning
