The Caribbean is one of the top six of the 25 global biodiversity conservation hotspots. These islands support populations of endemic plants and vertebrates amounting to at least 2% of the world's total species complement.
Due to increasing pressure from an expanding human population, islands throughout the region face the continuing erosion of pristine habitats. This is the problem of invasive alien species, hunting, illegal trade and more. As a result, over 10% of the region’s birds are considered globally threatened.
