More numerous are the various monkey, bat, and bird species. Other common animals include pangolins, porcupines and other rodents, and genets. Demographics Settlement patterns Over 324,000 Cameroonians live in the South Province, and the overall population density is about seven inhabitants per square km. The most populous area is the central region south of Cameroon's capital, Yaoundé, in the neighbouring Centre Province and extending south to Ebolowa, west to Kribi, and east to Sangmélima. The rest of the population lives in the villages and towns built around the roads that criss-cross the terrain. In contrast, the vast tracts of jungle that have little or no road access are scarcely populated. The forest area is also plagued by disease-carrying mosquitoes and blackflies that keep settlers away. Tradition settlements in the Centre are placed along roads, resulting in large numbers of houses near the road with forest beginning directly behind them. The traditional house is a rectangular structure made of mud bricks and thin, wooden or bamboo posts. Roofs were mostly thatched raffia palm in the past, but they are more often made of corrugated aluminium, iron, or tin today. People The majority of the inhabitants of the South are members of various Bantu tribes that are collectively known as the Beti-Pahuin (Béti-Pahouin), the Fang-Beti, or simply the Fang. All of these groups speak various dialects of the Beti language. In addition, most inhabitants of the more populated areas can also speak French. Beti-Pahuin The Beti portion of the group is primarily situated in the Centre Province, but large numbers of Ewondo and Bane inhabit the Ntem and the Dja and Lobo divisions of the South. The Fang group lives close to the province's southern borders. The Fang proper are inland on the border with Equatorial Guinea and near Djoum. The Ntumu inhabit the area around Ambam, also on the southern border. The Mvang (or Mvae) occupy the regions directly east and west of the Ntumu. These tribal groups have many more members in Equatorial Guinea, Gabon, and the Congo. The Bulu form the third group with about a third of the total Beti-Pahuin population. They are further broken down into the Bulu proper, who inhabit the rich cocoa producing area from Kribi to Ebolowa and east through Sangmélima and Djoum. Inland from Kribi live the Pahuin proper, centered on the villages of Bivouba and Fifinda. The Zaman occupy the valley of
