The Dzanga-Sangha Complex of Protected Areas (DSPAC) (originally: Dzanga-Sangha Project) is a protected area in the extreme southwestern Central African Republic. The dense forest block, created in 1990, measures 4,589 km² (1,772 sq mi). It consists of the Dzanga-Sangha Special Reserve and the Dzanga Ndoki National Park which has two sectors, the 495 km (308 mi) Dzanga Park and the 725 km (450 mi) Ndoki Park. Since their gazetting, management of the park and the reserve has been under the Dzanga-Sangha project, a collaborative effort of the country's government, the GTZ/LUSO, a German technical agency, and the World Wildlife Fund.
