of Guibourtia demeusii. There are several intact populations of key forest fauna including the western lowland gorilla, African forest elephant, chimpanzee, giant forest hog, red river hog, sitatunga, endangered bongo, African forest buffalo, and six species of duiker. The gorilla density of 1.6 individuals/km2 within the Dzanga sector is one of the highest densities ever reported for the western lowland gorilla. The Dzanga-Ndoki National Park has been designated an Important Bird Area (#CF008). The IBA is contiguous with two other IBAs, Lobéké of Cameroon (#CM033) and Nouabalé-Ndoki in Congo (#CG001). Over 350 bird species have been reported at the national park of which at least 260 can be expected to breed. Stiphrornis sanghensis has been described as a new species noted only within Dzanga-Sangha, but further investigation is pending as it may also occur in adjacent parts of Democratic Republic of the Congo, Cameroon and Republic of the Congo. In May 2013, the slaughtering of 26 African forest elephants by poachers in Dzanga Bai, a reserve in the World Heritage Site Sangha Trinational led to worldwide concern by conservationists.
