Invasive Species (Plants and Animals)
An "invasive species" is defined as a species that is:
- non-native (or alien) to the ecosystem under consideration and
- whose introduction causes or is likely to cause economic or environmental harm or harm to human
Invasive species can be plants, animals, and other organisms (e.g., microbes). Human actions are the primary means of invasive species introductions. (Executive Order 13112)
