The Western Congolian swamp forests (French: Forêts marécageuses de l'ouest du Congo) are an ecoregion of the Republic of the Congo, Democratic Republic of the Congo and adjoining Central African Republic. Together with the adjacent Eastern Congolian swamp forests, it forms one of the largest continuous areas of freshwater swamp forest in the world. It is a flooded forest with a high canopy, dense undergrowth and has a muddy floor. It has not been disturbed very much by outside influences and so remains largely pristine as getting through this forest is called "almost impossible".[2][3][4][5][6]
Location and description
This ecoregion stretches for 1,200 km along the west bank of the Congo River, from the town of Bolobo in the southwest to Yangambi in the east, both in the Democratic Republic of the Congo. The bulk of the territory is on the western half of this stretch; the eastern river portion is only a thin strip of group along the river. Mean elevation is 338 meters, ranging from 258 meters to 497 meters.[5] Much of the terrain sits on flooded and saturated soils classified as gleysols. The region is heavily forested and sparsely populated.[3]
The Congo River separates this ecoregion from the
Climate
The climate of the ecoregion is Tropical rainforest climate (Köppen climate classification (Af)). This climate is characterized as hot, humid, and having at least 60 mm of precipitation every month.[7][8] The rainy season is August to February.
Flora and fauna
The ecoregion contains areas of permanently flooded swamp forest, seasonally flooded swamp forest, and flooded grassland. The permanently flooded swamp forests are home to extensive stands of Raphia palm. 89% of the ecoregion is closed canopy forest of broadleaf evergreen, another 3% is open forest, 3% is herbaceous cover and the remainder is Trees in the seasonally flooded forests include species of Garcinia and Manilkara.
The ecoregion is home to the endangered western lowland gorilla (Gorilla gorilla gorilla) and African forest elephant (Loxodonta cyclotis).
Protected areas
59.4% of the ecoregion is in protected areas. They include:[5]
- Ngiri Triangle Nature Reserve
