The Juan Fernandez archipelago and Robinson Crusoe island
The Juan Fernández archipelago off the coast of Chile consists principally of two islands, one of which is the island Más a Tierra, renamed Robinson Crusoe island in 1966. 135 endemic species have been recorded there, one of the highest numbers in the world, resulting in its being declared a UNESCO World Biosphere Reserve in 1977.
Since the discovery of the archipelago, overexploitation of its forests, fires and overgrazing have altered the natural balance and brought about the loss of habitat of over 50 species, which are now in danger of extinction.
The introduction of exotic plant and animal species such as rats, rabbits and goats is relentlessly threatening the especially vulnerable indigenous flora. The landscapes of Robinson Crusoe island are becoming impoverished and the changes may be irreversible.
