All species of great apes are (critically) endangered; their continued existence depends on the conservation of the tropical rainforests. In the Congo Basin, the area inhabited by the chimpanzee, bonobo and gorilla, only 10–15% of the forests are legally protected, either as national park or nature reserve. The figure for South East Asia, where the orang-utan dwells, is about 20%. Many times that area of forest (in some countries up to 90%) is leased as logging concession. Effectively protected national parks and nature reserves are preferable habitats for great apes. However, since many great apes dwell in logging concessions, their continued existence depend, therefore, to a great extend on how well they can survive in these logging concessions.File Format: PDF · File Size: 2,73 MB · Added: Monday, 24.06.2013
