Vegetation description

Mangroves are located on the western coast and along the banks of the lower courses of rivers where these become tidal. They are more limited on the eastern coast, which is very steep, and not favourable for their establishment. The flora is relatively poor, with no endemic species. Rhizophora sp. is found along the sea coast, reaching a height of 2 to 5 m, and forms almost pure stands. A more diverse and taller forest (up to 8 m), is found along the tidal reaches of rivers and consists mainly of Bruguiera gymnorhiza, Rhizophora sp., Lumnitzera racemosa and Sonneratia alba.

Trends in mangrove area extent over time

The estimates for 1980, 1990 have been calculated applying the FRA 2000 (FAO, 2001) annual forest cover change rate 1980-1990 (-0.14 percent) to the most recent, reliable figure. The projection for 2000 is based on expert estimate.
