Africa isn't often called one of many extra densely populated continents. but, the dangerous marks of man's actions might be visible there dramatically. a lot of Africa's ecological zones are fragile. huge scale soil erosion, resul tant cycles of drought and flash floods, downgrading of fauna and flowers are famous to many mostly methods, in addition to from unique exam of some components. yet huge components of Africa stay inaccessible. only a few scholars of Africa give you the chance - or the tenacity - to go back and forth over those sizeable parts or into the hidden corners that lie past the well known routes of Africa. As FAO's nearby natural world and nationwide Parks Officer for Africa, ANTooN DE Vos had the potential of vacationing commonly and learning and reporting at the acceleration of synthetic adjustments in a lot of the continent. As an skilled practitioner of a tremendous and tough technological know-how, ecology, he has made an important expert contribution with this publication. it truly is our desire that those that learn will probably be inspired to carryon the real paintings and the worry with this topic to which Dr. DE Vos has committed loads of his wisdom, power and private commitments.

More extensive movements are undertaken by many ungulate species. The extent of ungulate movement varies not only from one species to another, but also within the same species in different areas of its distribution. The same species may be migratory or nomadic in one area, yet sedentary in another. The wildebeest for instance, is migratory in the Serengeti plains and is sedentary in the Ngorongoro crater. Both nomadism and migration of wild ungulates may be considered striking adaptations to the seasonality of many savanna areas.
Winter rains fall in the northern Sahara, summer rains in the south, and the central part has an irregular rainfall. In recent centuries no apparent decrease in precipitation has been noted. The prevailing wind is the northeast trade or 'Harmattan'. VEGETATION Contrary to opinion that the Sahara is a barren wasteland, most ofit has some plant cover. The number of species found, is, however, the lowest in the world, excepting the polar regions. Vegetation depends on the nature of the land surface and upon the presence of surface and 'Subsoil water.
Wherever natural tree cover remains it should be carefully protected. Particular attention should be paid to remnant Juniperus stands in the Sudan above 1250 m, because it is the tendency of this species to disappear. Podocarpus also faces danger of elimination, as it is being over-utilized for the production of roofing poles. Photo 6. Emaciated cattle in Upper Volta manage to reach a water hole. But with pastureland ravaged by drought, their chances of survival are poor. FAO photo taken during the drought of 1973.
