The Congolian rainforest is the world's second-largest
tropical forest, after the
Amazon rainforest. It covers over across six countries and contains a quarter of the world's remaining tropical forest. The Congolian forests cover southeastern
Cameroon,
Gabon,
Republic of the Congo, the northern and central
Democratic Republic of the Congo, and portions of southern and central Africa. The Congolian rainforest is home to a large number of flora and fauna, including more than 10,000 species of plants and over 10,000 species of animals. It is estimated that the region contains more than a quarter of the world's plant species and is home to one of the world's most threatened primate species, the
western lowland gorilla. There are also a number of other species of primates, including the
chimpanzee,
black colobus monkey,
red colobus monkey, and
olive baboon. The central Congo Basin is home to one of the world's largest tropical peatlands, extending along both sides of the Congo River and its tributaries. The
peat swamp forests in the Congo Basin store approximately 29 billion tons of carbon - equivalent to about three years worth of global greenhouse gas emissions. To the north, south, and southwest, the forests transition to drier
forest-savanna mosaic, a mosaic of drier forests,
savannas, and
grasslands. To the west, the Congolian forests transition to the coastal
Lower Guinean forests, which extend from southwestern Cameroon into southern
Nigeria and
Benin; these forest zones share many similarities and are sometimes known as the Lower Guinean-Congolian forests. To the east, the lowland Congolian forests transition to the highland
Albertine Rift montane forests, which cover the mountains lining the
Albertine Rift, a branch of the
East African Rift system.
Ecoregions The
World Wide Fund for Nature divides the Congolian forests into six distinct
ecoregions: •
Atlantic Equatorial coastal forests (Angola, Cameroon, Republic of the Congo, Democratic Republic of the Congo, Equatorial Guinea, and Gabon) •
Central Congolian lowland forests (Democratic Republic of the Congo) •
Eastern Congolian swamp forests (Democratic Republic of the Congo) •
Northeastern Congolian lowland forests (Central African Republic and Democratic Republic of the Congo) •
Northwestern Congolian lowland forests (Cameroon, Central African Republic, Gabon, and Republic of the Congo) •
Western Congolian swamp forests (Republic of the Congo and Democratic Republic of the Congo) ==Flora and fauna==
