Brief synthesisCocos Island National Park is located in the Eastern Tropical Pacific, covering an area of 202,100 hectares some 530 kilometers off the Costa Rica mainland. The island itself, “Isla del Coco”, also known as “Treasure Island”, is the only landmark of the vast submarine Cocos Range. Cocos Island National Park is of irreplaceable global conservation value, reminding us what parts of tropical oceans historically looked like. Criterion (x): The small island supports the only tropical forest ecosystem located on an oceanic island within the Tropical Eastern Pacific. Cocos Island National Park cannot achieve the long-term conservation of species indiscriminately exploited in the wider Eastern Tropical Pacific and elsewhere.
