The exotic mammals in South America represent about 20 % of world mammal introductions. We recorded feral populations of 18 species of exotic mammals for Argentina. The majority of introductions ocurred between 18th and 20th centuries and their ports of entry were located in temperate ecosystems, between 34° and 55°S. The majority of the species are from Eurasia, and most of their entry pathways were associated with human activities. The wild boar was introduced in 1906. Then many individuals escaped and established like feral population. Its potential impact include: large areas bare of vegetation, frugyvory and seed predation, predation on soil nesting birds and eggs, bark damage to keystone species like Prosopis flexuosa, and damage to crops and transmission of diseases to human.
