Site description The site consists of the islands of Bazaruto, Santa Carolina, Benguerra and Margaruque, and also the San Sebastião peninsula on the mainland. There are high sand-dunes on the eastern side, but the rest of the land area is flat. The most important habitat for birds is the extensive intertidal flats which connect the islands. Vegetation on the islands is mostly scrubby, with a small patch of moderately well developed woodland on Benguerra island. Several freshwater lakes occur on Bazaruto island. The San Sebastião peninsula has well developed woodlands and forest and extensive marshes. The human population is dense on the islands and sparse on the peninsula. Human activities consist of subsistence farming and fishing. There is a well developed infrastructure for tourism.

Other biodiversity The islands support six endemic species of gastropod (Conus pennaceus, Epitonium pteroen, E. repandior, Fusiaphera eva, Thracia anchoralis, Limatula vermicola). Two lizard species are endemic to Magaruque and Benguera (Scelotes duttoni, Lygosoma lanceolatum). The following marine mammals are of conservation concern: Megaptera novaeangliae (VU), Tursiops truncatus (DD), Sousa chinensis (DD), Dugong dugon. Due to disturbance and persecution, sea-turtles have abandoned many breeding beaches in Mozambique, but here breeding by Caretta caretta (EN) is confirmed and breeding by Dermochelys coriacea (CR) and Eretmochelys imbricata (CR) is probable.
