The maps are from Discover Life, an organization that specializes in
identifying species and representing biodiversity around the world. The
maps are potentially helpful in determining the extent that invasive
species has spread; the geographic location of where the species is found
is plotted on these maps. For each invasive species, provide its full
scientific name and match the provided map based on the extent of
infestation and also the region of the original native populations.
