Why is it a problem?
- The first invasive aquatic plant documented in Alaska
- Forms dense mats that displace and shade out native aquatic vegetation
- Increases water turbidity, alters water chemistry
- Degrades habitat for native salmon and other fish species
- Plant fragments are easily spread on boats, trailers, floatplanes, fishing gear, and other equipment – a single plant fragment can quickly grow into a large infestation
- Survives extended periods of freezing and drying out
- Creates hazardous and undesirable conditions for boaters, floatplane pilots, and swimmers
- Large infestations reduce the scenic quality of natural settings and reduce property value
How do I manage this plant?
- Eradication is labor intensive and can be quite expensive – prevention is key!
- Mechanical control causes stem fragmentation and makes removal efforts counterproductive. If using manual or mechanical control, use extreme caution to ensure all plant fragments are removed.
- Clean, drain, dry, and inspect boats and gear before moving between waterbodies. Remove any plant parts found, and dispose of them in the trash.
- Learn to identify Elodea and report any sightings.
