Invasive species are often grouped by threat levels that vary from county to county from very high impact to remarkable increased growth. The species below are by no means comprehensive and are listed in type order rather than level of threat [ 1 ] [ 2 ] [ 3 ]
“Invasive plants proliferate themselves at a high rate, which makes them alarming,” says Amanda Bennett, vice president, horticulture and collections, at Atlanta Botanical Garden. “It’s ...
This is a list of invasive species in North America.A species is regarded as invasive if it has been introduced by human action to a location, area, or region where it did not previously occur naturally (i.e., is not a native species), becomes capable of establishing a breeding population in the new location without further intervention by humans, and becomes a pest in the new location ...
Non-native invasive species can disrupt ecosystems because they do not have natural predators, or other ecological checks-and-balances. Thus, with less competition from native species, non-native populations can explode. [9] Invasive insects and pathogens have eliminated entire tree species from forests of the United States in as little as decades.
The economic impacts of invasive species can be difficult to estimate especially when an invasive species does not affect economically important native species. This is partly because of the difficulty in determining the non-use value of native habitats damaged by invasive species and incomplete knowledge of the effects of all of the invasive species present in the U.S. Estimates for the ...
