As per Executive
Order 13112 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.
Invasive species can be plants, animals, and other
organisms (e.g., microbes). Human actions are the
primary means of invasive species introductions. For
