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 to new environments than any single document can record. This list is generally for established species with truly wild populations— not kept domestically, that have been seen numerous times, and have breeding populations. While most introduced species can cause a negative impact to new environments they reach, some can have a positive impact, just for conservation purpose.
