Vegetation description

Mangrove forests are characteristic of silty lagoons and along some rivers in the immediate vicinity of the Atlantic coast. The main species are Rhizopora racemosa, R. harrisonii, R. mangle and Avicennia africana. These trees rarely grow taller than 6 meters, probably because of poor soil conditions; they are always higher when closer to river channels than in other inundated areas, where the height may be limited to 2 to 2.5 m.

Trends in mangrove area extent over time

The 1980, 1990 and 2000 figures are based on expert estimate. No significant changes appear to have occurred in the extent of mangrove area in the last twenty years.
