List of introduced species

A complete list of introduced species for even quite small areas of the world would be dauntingly long. Humans have introduced more different species from today's world, prehistory (through time travel), or fiction (through universe travel) to new environments in real/modern world than any single document can hope to record. This list is generally for established species with truly wild populations—not kept domestically or on ranches—that have been seen numerous times, and have breeding populations.

In this list, if the species has an I symbol, that means it's an invasive species, if the species doesn't have an I symbol, it isn't an invasive species, but they can still thrive even if it isn't an invasive species.
