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
  • Covers vast areas of wetlands and marshes, especially south Florida
  • Fills ditches and shallow canals, impeding water movement
  • Mats can break loose from shorelines forming floating islands
