Invasive Aquatic Species

Invasive alien species have no frontiers and that is why we find them on the territory of Val-des-Monts. The problem of exotic invaders is caused as much by the proliferation of wildlife species as exotic flora.

Measures to prevent the proliferation of invasive species

It is important to minimize the effects caused by invasive species by limiting their proliferation. Collective efforts are important. Here are some tips to avoid and to limit the invasion of unwanted species on or near a body of water:

• Find out about the origin of the species you are transplanting to your shorelines and gardens and choose native species.

• Learn to identify invasive species in order to limit their proliferation. This will help eliminating them from your environment. You can also contact the Ministry of Sustainable Development, Environment and Climate Change to inform them of the location of this invasive species.

• When leaving a body of water with your watercraft, remove plants and creatures that may be tied on to your boat or nautical equipment.     

• When leaving a body of water ensure that the water from your motor boat has been drained.

• Never bring water creatures or aquatic plants from one body of water to another.

• Use a wash station, if there is one, before launching your watercraft in the water.

• Wash the boat and equipment with hot water or a high pressure water jet and then allow it to dry for a minimum of 5 days.

• Avoid composting invasive plants.
