10. 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)

21. 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.
