An invasive species is an introduced species that harms its new environment. [2] Invasive species adversely affect habitats and bioregions, causing ecological, ...
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 ...
The range of the common myna is increasing at such a rapid rate that in 2000 the IUCN Species Survival Commission declared it one of the world's most invasive species and one of only three birds listed among "100 of the World's Worst Invasive Species" that pose a threat to biodiversity, agriculture and human interests.

Invasive species are only considered invasive if they are able to survive and sustain themselves in their new environment. [1] A habitat and the environment around it has natural flaws that make ...
Introduced species. An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally.
Native species. Large-leaved lupine (Lupinus polyphyllus): native to western North America but introduced and invasive in several areas worldwide. In biogeography, a native species is indigenous to a given region or ecosystem if its presence in that region is the result of only local natural evolution (though often popularised as "with no human ...
