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.
