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)
2nd threat to biodiversity claim, but open it up for discussion later

Invasive plants wouldn't do nearly as well in nature without human activity & disturbance.
In other words: We're already managing
for them – but not how we want to.
