A mosaic of rivers, forests, savannas, swamps and flooded forests, the Congo Basin is teeming with life. Gorillas, elephants and buffalo all call the region home. The Congo Basin spans across six countries—Cameroon, Central African Republic, Democratic Republic of the Congo, Republic of the Congo, Equatorial Guinea and Gabon. There are approximately 10, 000 species of tropical plants in the Congo Basin and 30 percent are unique to the region. Endangered wildlife, including forest elephants, chimpanzees, bonobos, and lowland and mountain gorillas inhabit the lush forests. 400 other species of mammals, 1,000 species of birds and 700 species of fish can also be found here. The Congo Basin has been inhabited by humans for more than 50,000 years and it provides food, fresh water and shelter to more than 75 million people. Nearly 150 distinct ethnic groups exist and the region’s Ba’Aka people are among the most well known representatives of an ancient hunter-gatherer lifestyle. Their lives and well-being are linked intimately with the forest.
