eurasian water-milfoil

Origin:

Europe, Asia, northern Africa

Identification:

Eurasian water-milfoil produces small red flowers on top of the water in mid-summer. They have about twice as many leaflet pairs(12-21) compared to native watermilfoil(5-10).

Impacts:

Forms dense stands of vegetation in the water column and thick mats at the surface, shading out native vegetation and reducing oxygen levels during decomposition. This dense vegetation also takes away from recreational activities.

Range Expansion:

Reproduces by fragmentation. Plant fragments are easily transported in livewells, bilge water, and on boat trailers.

Keep Aquatic Invasive Species Out of South Dakota's Waters

ALWAYS DO:

  • Remove aquatic plants and animals before leaving any waterbody.
  • Drain water from bait bucket, live well, bilge and motor before leaving any waterbody.
  • Dispose of unwanted bait, fish parts, and worms in the trash.
  • Spray/wash boat, trailer, and equipment with high pressure hot water on your way home or at home -OR- dry everything for at least 5 days.
  • Always report questionable species.

NEVER DO:

  • Never release live animals or plants - this includes all aquarium species, bait, pets or water garden plants. Do not release these into the wild. If you cannot find another home for animals, dispose of them in a trash can or bury them. Seal plants in plastic bags and dispose.

WHY?

Because these hitchhikers can:

  • Reduce game fish populations
  • Ruin boat engines and jam steering equipment
  • Make lakes/rivers unusable by boaters and swimmers
  • Dramatically increase the operating costs of drinking water plants, power plants, dam maintenance, and industrial processes
  • Reduce native species
  • Degrade ecosystems
  • Affect human health
  • Reduce property values
  • Affect local economies of water-dependent communities.
