INVASIVE SPECIES DEFINITION
Plants, animals, and microbes not native to a region which, when introduced either accidentally or intentionally, out-compete native species for available resources, reproduce prolifically, and dominate regions and ecosystems. Because they often arrive in new areas unaccompanied by their native predators, invasive species can be difficult to control. Left unchecked, many invasives have the potential to transform entire ecosystems, as native species and those that depend on them for food, shelter, and habitat, disappear.

WHAT ARE THE ECOLOGICAL IMPACTS ON
INVASIVE SPECIES: HOW SERIOUS A PROBLEM ARE THEY?
Estimate: costs of invasive species in the United States ~$125-140 billion each year.
Estimate: 25% of US agriculture gross national product lost to foreign pests.
Nearly half of the species listed as threatened or endangered under the Endangered Species Act are at risk due to competition with or predation by non-native species.
It should also be noted that there is not much support for measures by the 'average citizen' (especially if an invasive animal species is cute, an invasive plant species beautiful), and that the severity of the problem is strongly underestimated.
