Here, we report on the population growth of 15 species of mammals introduced in 1983 on the island of Anchieta, an 828ha land-bridge island in southeastern Brazil. We estimated the density of mammals through 296km of line transect census. Five species introduced became extinct (coypu, brocket deer, six-banded armadillo, nine-banded armadillo, maned three-toed sloth); six became over-abundant (marmoset, coati, agouti, seven-banded armadillo, and capybara); one has a stable population (capuchin monkey). Anchieta Island has the highest density of mammals in the entire Atlantic forest (486.77ind/km2), especially nest predators (232.83ind/km2) and herbivores (253.58ind/km2). Agoutis (Dasyprocta spp.) and marmosets (Callithrix penicillata) were, by far, the species with the highest population growth. The high density of mammals in this island may have strong consequences for plant recruitment and bird diversity.
