Eastern chimpanzee and Western Lowland gorilla numbers in Central African Republic remain unknown due to the political and civil instability that make population surveys impossible. Chimpanzee habitat in southeastern Central African Republic has virtually disappeared due to human encroachment. Chimpanzees are now located in forests along the eastern border with South Sudan and Sudan, where the human population is very small. However, there is only one protected area in the region (Zemongo Faunal Reserve) and illegal travels of Sudanese poachers and armed militia are increasingly common, as well as poaching by shepherds and refugees from South Sudan.
