TEACH Invasive Species

6 | How can you prevent the spread of nonindigenous species?

  • The first step is learning to correctly identify exotic species. A good source for links to species descriptions and photographs is the GLIN Invasive Species section. These sites will help you recognize nonindigenous species as you travel the Great Lakes.
  • Never use exotic species as bait and never release aquarium plants and animals into the wild.
  • Transporting exotic species on boats and other personal watercraft is another way exotic species are spread. The Minnesota Department of Natural Resources' web site describes the proper way to clean a boat to prevent the transport of non-native species from one waterbody to another.
  • While nonindigenous plants are commonly sold in nurseries and garden centers, consider the benefits of planting only native species in your yard. See also: U.S. EPA's Landscaping With Native Plants
  • Report sitings of invasive species to relevant agencies, such as your state/provincial department of natural resources or your local Sea Grant office.
