Интродукция
Virtually the entire land area of the islands is used as pasture for sheep. Introduced species include reindeer, hares, rabbits, Patagonian foxes, brown rats and cats. Several of these species have harmed native flora and fauna, so the government has tried to contain, remove or exterminate foxes, rabbits and rats. Endemic land animals have been the most affected by introduced species, and several bird species have been extirpated from the larger islands. The extent of human impact on the Falklands is unclear, since there is little long-term data on habitat change.
