DefenselessMany island types evolved in the lack of predators, an interpretation they don’t have defense mechanisms the other types might have, such together flight, camouflage, poison, or weaponry. If invasive predators enter an island species’ habitat, the native varieties are no equipped come cope through the brand-new threat.

Island Conservation stays clear of extinctions by removed invasive types from islands. Come date, we have actually successfully revived 65 archipelago worldwide, services 1218 populations of 504 species and subspecies. Working together with local communities, government management agencies, and conservation organizations, we select islands that have actually the greatest potential for avoiding the die out of around the world threatened species.
