Site description The site is a coral island in the central Mozambique Channel, lying around 200 km west-south-west of Cap Saint André, Madagascar. Its ecosystems were severely degraded by human settlement for guano extraction until 1972. Only two naturalists have visited the site since the 1950s, but the vegetation is believed to be low shrubland. The island is used by the military, and also supports a meteorological station.
