The Congolian rainforests are a broad belt of lowland
tropical moist broadleaf forest
Tropical and subtropical moist broadleaf forests (TSMF), also known as tropical moist forest, is a subtropical and tropical forest habitat (ecology), habitat type defined by the World Wide Fund for Nature.

Description

The Congolian rainforest is the world's second-largest
tropical forest, after the
Amazon rainforest
The Amazon rainforest, Amazon jungle or ; es, Selva amazónica, , or usually ; french: Forêt amazonienne; nl, Amazoneregenwoud. In English, the names are sometimes capitalized further, as Amazon Rainforest, Amazon Forest, or Amazon Jungle. ...
. 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.
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

Ecoregions
The
World Wide Fund for Nature divides the Congolian forests into six distinct
ecoregions:
*
Atlantic Equatorial coastal forests (Cameroon, Equatorial Guinea, Gabon, Republic of the Congo, Angola, Democratic Republic of the Congo)
*
Northwestern Congolian lowland forests (Cameroon, Central African Republic, Gabon, Republic of Congo)
*
Western Congolian swamp forests (Republic of the Congo, Democratic Republic of the Congo)
*
Eastern Congolian swamp forests (Democratic Republic of the Congo)
*
Central Congolian lowland forests (Democratic Republic of the Congo)
*
Northeastern Congolian lowland forests
The Northeastern Congolian lowland forests is a tropical moist broadleaf forest ecoregion that spans the Democratic Republic of the Congo and the Central African Republic.

Flora and fauna

The Congolian rainforests are home to over 10,000 species of plants of which 30% are
endemic.
The Congolian rainforests are less biodiverse than the Amazon and
Southeast Asian rainforests. However, its plant and animal life is still more rich and varied than most other places on Earth. The Congolian Forests are a
global 200 ecoregion.
There are over 400 species of mammals in the rainforest, including
African forest elephants,

Conservation
Threats to the rainforests include destruction and fragmentation of forests by commercial logging, oil palm plantations, and mining. The bushmeat

a primary source of animal protein and a cash-earning commodity for inhabitants of humid tropi ...
trade and poaching is depleting the rainforests of wildlife. With annual forest loss of 0.3% during the 2000s, the region has the lowest deforestation rate of any major tropical forest zone.
