WHAT IS AN ALIEN SPECIES?
An alien species is a non-native species whose interaction causes economic harm, harm to human
health and/or environmental harm. Invasive species are often likened to “super-bugs”. These
“super-weeds” have abilities to reproduce and survive that far exceed their native counterparts.
Invasive plants quickly displace native vegetation and completely take over sensitive ecosystems
as they have no natural predators (i.e. diseases, fungi, insects) in their non-native environment.
