The Ramsar Convention is an international treaty that protects wetlands of great international importance with emphasis on the significance of waterfowl. All Ramsar sites registerd by the Netherlands Antilles lie within Bonaire: Lac, Pekelmeer, Klein Bonaire, Gotomeer and Slagbaai Lagoon.
Bordered by globally endangered mangroves, numerous waterfowl breed and feed in the area of Lac. The Flamingo Sanctuary at Pekelmeer is one of the most important breeding grounds for the Southern Caribbean Flamingo population (+/- 6,500). Klein Bonaire, encircled by a great coral reef, offers flamingo feeding and turtle nesting areas. Gotomeer, foraging site for hundreds of flamingos, contains the most important food source for flamingos: brine fly and larvae. Slagbaai lagoon is a foraging and breeding site for flamingos and other birds like pelicans and herons.
