Invasive Plants

Non-native, invasive plants are sometimes the exotic ornamental plants that homeowners and landscapers put in flower beds, yards, and along roadsides. While others are referred to as noxious weeds. Though exotics sometimes look pretty, if they are invasive when they escape into the wild, they can pose serious environmental threats.

What is an Invasive Plant Species?

An “invasive species” is defined as a species that is

  1. Non-native (or alien) to the ecosystem under consideration; and,
  2. Whose introduction causes or is likely to cause economic or environmental harm or harm to human health.
