Created in 1993, the Nouabalé-Ndoki National Park (NNNP), situated in the Sangha and Likouala department in northern Republic of Congo, covers an area of 4,238.7 km2 and is home to important populations of forest elephants, western lowland gorillas, chimpanzees, bongo, and many other endangered mammals.
The Nouabalé-Ndoki forest is part of the larger Sangha Trinational Forest Landscape that in July 2012, was nominated as a World Heritage Site. It extends over approx 35,000 km2 and comprising a vast stretch of lowland Guineo-Congolian forest, rich in African mahoganies and large mammals with important forest clearings. The entire park consists of pristine unlogged rainforest including a rich diversity of old growth endangered mahoganies, and boasts over 300 bird species, 1,000 plant and tree species, and intact populations of large mammals. These large mammals include several endangered species, such as western lowland gorillas (Gorilla gorilla), chimpanzees (Pan troglodytes troglodytes), forest elephants (Loxodonta africana cyclotis), bongo (Tragelaphus euryceros), and forest buffalo (Synceruscaffer nanus).
NNNP provides integral protection to wildlife through a collaborative management program between the Wildlife Conservation Society (WCS) and the Congolese Ministry in charge of Forests and Water. The NNNP is a rare example of an intact forest wilderness, completely uninhabited by human settlers and with extremely low human population densities in the surrounding area.
