This is a big, green forest. 

This is a very large forest in Africa. 

The Congolian rainforest is a huge forest in Africa. 



The Congolian rainforest is a huge, green belt in Central Africa. 

Many different living things live in these woods. There are over 10,000 kinds of plants and 10,000 kinds of animals. Some plants are endemic, which means they grow nowhere else. 

Nature changes as you move through the landscape. To the north and south, the forest turns into dry savannas. To the west, it meets the coastal Lower Guinean forests. To the east, the land rises into the Albertine Rift mountains. 
One amazing part of the forest is the central Congo Basin. This area has one of the largest tropical peatlands in the world. Peatlands are thick, wet layers of old plant matter. 
People face many hard jobs when trying to save this forest. Commercial logging and mining can destroy the trees. Oil palm plantations also take up space where trees once grew. 
The Congolian rainforests are a massive belt of lowland tropical moist broadleaf forests. 

The forest is a complex system of different environments. To the north, south, and southwest, the moist rainforest transitions into a forest-savanna mosaic. This mosaic consists of drier forests, savannas, and grasslands. To the west, the area meets the coastal Lower Guinean forests. These coastal forests extend from southwestern Cameroon into southern Nigeria and Benin. To the east, the lowland forests change into the highland Albertine Rift montane forests. These mountains line the Albertine Rift, which is a branch of the East African Rift system. 
Scientists divide the Congolian forests into six distinct ecoregions. These help us understand the specific characteristics of different areas. The Atlantic Equatorial coastal forests span Angola, Cameroon, Republic of the Congo, Democratic Republic of the Congo, Equatorial Guinea, and Gabon. The Central Congolian lowland forests are located in the Democratic Republic of the Congo. There are also Eastern Congolian swamp forests and Western Congolian swamp forests. Both of these swamp regions are found within the Democratic Republic of the Congo and the Republic of the Congo. Finally, the Northeastern Congolian lowland forests cover the Central African Republic and the Democratic Republic of the Congo.
The biodiversity within these forests is incredibly high. The region contains more than 10,000 species of plants and over 10,000 species of animals. About 30% of the plant species are endemic, meaning they are found nowhere else on Earth. 

Birds and fish also thrive in this massive ecosystem. There are 1,000 native species of birds, such as the grey parrot, brown nightjar, and the bat hawk. In the waters, 700 species of fish live, including the Nile tilapia, Nile perch, and the giraffe catfish. 
Despite its importance, the rainforest faces many serious threats. Commercial logging and mining cause the destruction and fragmentation of forests. Large oil palm plantations also take up space previously held by trees. The bushmeat trade and poaching are also depleting the wildlife populations. 
The health of the Congolian rainforest is closely tied to the global environment. The massive amount of carbon stored in the peatlands helps regulate the planet. When these forests are lost, that stored carbon can be released. This makes the protection of the Congo Basin a vital task for the whole world. Understanding the different ecoregions and species helps scientists track these changes. Protecting the habitat of the western lowland gorilla and the okapi is also a key part of conservation efforts.
