Site description Navassa Island IBA is situated 53 km west of Haiti, 136 km east of Jamaica and 152 km south of Cuba. The IBA includes the 500-ha island and marine areas up to 22 km from it, thus covering 147,600 ha of open ocean. Navassa is a small, pearshaped island plateau that rises abruptly from deep water. It is surrounded by a series of submarine coralline terraces. The karst dolomite terrain slopes from the lower north-western edge towards the south-eastern side and supports upland evergreen woodland and sparse shrubby vegetation. The island is surrounded by a submerged coral reef ecosystem and open sea.
