An invasive species is an organism that is able to proliferate and persist in a new range, such that it has adverse ecological consequences on the ecosystem in which it is present. Reduced biodiversity due to loss of native species. 2005 economic loss in great lakes basin estimated at billion due to: Reduced value of recreational and commercial fishing.
