What

What you can do

The first line of defense in the fight against aquatic weed invasions is public awareness and the ability to tackle weeds before they get out of hand – at the first sign of a new plant, rather than a total infestation.

  • Don't be a spreader – check boats, trailers and fishing gear for plants when you leave the water.
  • Be observant – note any change in natural and ornamental ponds and waterways.
  • Disposal of unwanted aquatic plants – do not dump into lakes and waterways.
  • Know your enemy:
    • Check out the web photos and plant identifications.
    • Collect samples and get them identified if in doubt.
  • Check plants being sold through petshops and garden centers – these have been a key outlet for new weeds in the past.
  • School projects:
    • How many different aquatic plants can you identify?
    • Which plants are native and which are introduced in your local lake or waterway?
    • How do dense weed beds effect water quality?
  • Communication – talk to friends, neighbours, and other boat users.
  • Be proactive in your local clubs (gardeners, boaties and aquarium, etc.), where you can increase aquatic plant awareness.
  • Establish a lake watch group for your area to facilitate awareness and action on lake issues.
