The Cuvette Centrale (French: "Central Basin") is a region of forests and wetlands in the Democratic Republic of the Congo. The Cuvette Centrale lies in the center of the Congo Basin, and is bounded on the west, north, and east by the arc of the Congo River. A lake covered the region during the Pliocene epoch, which was gradually filled with sediments, and the surface of the basin is very flat. Slow-moving tributaries of the Congo, including the Lopori, Maringa, Ikelemba, Tshuapa, Lomela, and Lokoro, drain westwards. The region lies on the Equator, and the climate is tropical and humid, and rainfall averages 2,000 mm annually. The Eastern Congolian swamp forests extend along the Congo River and its chief tributaries, and cover wide areas in the western portion of the Cuvette Centrale. These swamp forests are seasonally or permanently flooded. The Central Congolian lowland forests extend across the remaining portion of the region. ==References== * Toham, Andre Kamdem ''et al.'', eds. (2006).
