Wild Boar Invasion in Argentina and Chile: Ecology, Impacts, and Distribution

About 2.6% of extant terrestrial mammals are “successful invaders.” These include the artiodactyls (pigs, camels, deer, cattle, sheep, goats, and antelope), carnivores (canids, bears, mustelids, and cats), lagomorphs (rabbits and hares), and perissodactyls (equines). In particular, the large ungulates (artiodactyls and perissodactyls) represent the highest proportion of invasive mammals, the family Cervidae being the most successful because of their aesthetic and economic appeal as big game animals (Clout and Russell 2008).
