Share of forest area in total land area, top countries (2021). Gabon has the fourth highest percentage of forest cover in the world.

Narrow coastal plain with patches of Central African mangroves; hilly interior; savanna in east and south. A recent global remote sensing analysis suggested that there were 420 km2 of tidal flats in Gabon, making it the 50th ranked country in terms of tidal flat area.[1]
