A complete List of introduced species for even quite small areas of the world would be dauntingly long. Humans have introduced more different species to new environments than any single document can hope to record. The following list of introduced species, in other words, is hopelessly incomplete.

Australia

Australia has a huge range of introduced species, so sub-classifications are necessary:

• Invasive - species has a tendency to spread their range into new areas
• Ferals - defined as animals for domestic purposes (ie. pets or Beasts of Burden) which have gone wild.
• Pests - animals which have a direct effect on human standard of living or the environment/ecosystems in areas where they are present, have a high rate of reproduction and are difficult to controlVertebrates
