Dja

In west-central Africa, the Dja River (also known as the Ngoko River) is a stream. It runs for approximately 720 kilometers along the Cameroon–Republic of Congo border (450 mi).

The Dja Faunal Reserve, which was proclaimed a UNESCO World Heritage Site in 1987 and rises southeast of the southeastern Cameroon town of Abong-Mbang, sits along the upper course of the river. It safeguards one of Africa's greatest swaths of tropical rainforest. Cliffs run along the path of the river in the south part of the reserve for 60 km, almost completely surrounding the reserve (save to the south-west). They are related with a segment of the river that is broken by rapids and waterfalls. The Dja flows southeast past Moloundou, below which small boats can navigate, following its course in the reserve. It empties into the Sangha River at Ouesso, Republic of Congo.

Poachers travel up the Dja every year in search of elephant ivory in central Nki National Park. For half of the year, the river's strong currents act as a deterrent, but after that, according to freelance writer Jemini Pandya, the fauna becomes easy prey.
