Atlantic salmon are native to the Atlantic Ocean but have been brought to northern Pacific Ocean waterways for fish farming. This invasive species threatens native salmon populations, an important fisheries staple, by competing for food and habitat and introducing new diseases.

The Norway rat, native to China, threatens Alaskan wildlife and vegetation. This invasive species eats anything smaller than it is, such as small birds and reptiles, and introduces harmful diseases. It consumes seeds and seedlings, thus altering vegetation communities by limiting plant regeneration.

Lymantria dispar is an invasive forest pest from Europe. The larvae (immature stage of the adult moth) can defoliate (remove leaves of) trees. Without its leaves, a tree loses its ability to photosynthesize and thus survive. Fewer trees could cause a huge drop-off in revenue generated from forestry, logging, and the timber trade.
