7 The annual average temperatures are between 23.4° in the West (Bouar) and 26.5° in the North East (Birao). The greater part of Central African territory receives more than 1,220mm of rain per year. Only the sub-Sahelian area of Birao receives less than a metre of rain per year. e Vegetation The Central African climate marked by strong rainfall provides the country with vegetation which is characterized by a large diversity of dense forests in the South and West of the country, with arborous and herbaceous Savannah in the North going through jungles of dry Savannah forests up to the Steppes in the extreme North East of the country. The variety of vegetation which also gives rise to varied climatic conditions is the source of important and diversified fauna. It is possible to find species like mammals (gorillas, elephants, rhinoceros, hippopotami, giraffes, antelopes…) reptiles (the viper, crocodiles, alligators��) and all kinds of birds. The aquatic fauna is rich in fish. With respect to the development and protection of the fauna, the Central African Republic has three national parks the most important of which include: the Avakaba Park in Bamingui-Bangoran in the North East of the country and the Zangha-Sangha Park in the Sangha Mbaéré Prefecture in the South East. The faunal heritage of the CAR, added to the variety of its vegetation, its water resources and its climate makes the country a tourist zone par excellence. However it should also be emphasized that these riches constitute a focus of attraction for the poachers who are decimating the rare and protected species (elephants, rhinoceros…) f Administrative Divisions The Central African Republic is divided into sixteen Prefectures. These are in turn sub-divided into seventy one (71) Sub-Prefectures, two (2) Administrative Offices (PCA), one hundred and seventy one (171) Administrative Districts and nine thousand (9000) villages. Within the context of the decentralization policy, the Prefectures are divided into six (6) regions, each having between two to three Prefectures. The seventh region is made up of eight Districts which constitute the Capital, Bangui. The major Administrative Departments are located in each region: the Military, the Health Services, the Inspectorates of Education, and of Labour, the regional Departments of the Public Service and in the near future the regional Departments of the Office of Human Rights and Good Governance. All the cities of the Central African Republic are linked by non bituminized roads with the exception of the three road links: Bangui-M’baiki, Bangui-Sibut and BanguiBossembélé-Garouamboulaye where road works are currently going on. The tracks which link the different towns in the country are quite accessible. During the rainy season traffic is made difficult due to the terrible degradation of the roads. The town of Birao in the extreme North of the country is completely cut off during the rainy season due to flooding and the absence of art works (bridges).
