How are they introduced and spread?

firewood
Invasive species can spread to new areas in firewood, causing new infestations.

Invasive species are introduced and spread in a variety of ways, including:

  • as goods such as plant products, firewood, hay, or wood packaging;
  • as live food imports;
  • as horticultural imports;
  • through vehicles such as aircraft, commercial and recreational boats;
  • ballast water from large ships; and
  • wildlife disease

Invasive plants are introduced and spread by: 

  • Improper disposal of garden plants. Please do not recycle garden debris into public parks or open areas such as ditches. Never compost. Instead, bag and incinerate at your local landfill.
  • Unintentional dispersal. Without their natural predators and pathogens, invasive plants spread quickly all on their own!
  • Intentionally as garden ornamentals. Please do not trade or purchase known invasive plants. To learn more, visit the section for Gardeners under You Can Help.
