1) What makes an organism an invasive species versus just an introduced species?

To be invasive, a species must adapt to the new area easily. It must reproduce quickly. It must harm property, the economy, or the native plants and animals of the region. Many invasive species are introduced into a new region accidentally.

An introduced species is a non native species that has one way or another been integrated into the native environment by human or other means. ... An invasive species on the other hand is an introduced organism that has become detrimental to the local environment.
