Site description Le lagon de la Nouvelle-Calédonie se divise, au sud, en deux cornes. La première contient la réserve Merlet, la passe de la Sarcelle et l’île des Pins. La seconde, identifiée comme une IBA et communément appelée corne Sud, contient 23 îlots, situés au sud de la commune du Mont Dore. Le récif barrière, qui ceinture l’IBA, est distant de 70 km de la côte. A cet endroit le lagon est donc le plus large du territoire, sa profondeur varie quant à elle entre 20 et 80 m.

Other biodiversity Les autres richesses naturelles de cette zone sont essentiellement marines. Un inventaire en a été fait lors d’un atelier d’identification des aires de conservation prioritaires (Cros et al. 2005). Il y est en outre signalé que cette région abrite les plus importantes biomasses de poissons de toute la Nouvelle-Calédonie, la présence de tortues (Chelonia mydas et Caretta caretta) et de vastes herbiers de Caulerpe.
