dc.description.abstract This study represents an ecological survey of the Khartoum district which lies between latitudes 16°N 15'W and 32°45'E and occupies an area of about 1.020 sq. m. Part I deals with the geology of the area and also the quemorphological patterns and the types of the landform units. A brief description of the main soil types of the district is given. An assessment of the climatic conditions (arid climate) and a review of the previous ecological studies are also included in this part. Part II deals with plant life. It gives the detailed description of the thirteen community types which are recognized as the principal unit of the vegetation of the district. For each community type, the analytic, synthetic and habitat characters are given. Each community type is named after the dominant species. The thirteen types are: 1) Aristida funculata, 2) Cymbopogon proximus, 3) Panicum turgidum, 4) Cassia senna, 5) Calotropis procera, 6) Salvadora persica, 7) Capparis decidua, 8) Acacia ehrenbergiana, 9) A. nubica, 10) A. tortilis, 11) A. seyal, 12) A. albida, 13) A. nilotica. Part III gives the general features of the vegetation of the Khartoum district. Sociological ranges of species, features which characterize each community type and floristic similarities and differences between the community types are discussed. The vegetational dynamics are outlined. The distribution of the thirteen community types rated to soil types, water supply and the biotic factors of human interference – direct in the form of removal of soil and firewood and indirect in the form of grazing and browsing of animals is described. Similarities and differences between the habitat types are outlined. en_US
