The first problems came when the island was discovered because the overgrazing by goats, cattle, sheep, horses and rabbits affected causing an irreversible erosion. The rats came too,that become in predadors of birds.
Also new plants arrived whit the immigrants, and colonized the land and expelled the vegetation which had begun to develop for more than 4 million years.
The South American Coati were released here to provide a wildlife more interesting when the island were designated a national park in the 1930s, but became in predators of a seabird which only nests in burrows.
