Ecology and Economic Importance of Some Representative Grasses & Shrubby Vegetation in the Semi- Desert of the Sudan

Abstract

This study was conducted in Algetaina locality, White Nile State. Sudan November 2005. Three sites were selected randomly in North-East of Algetaina at Qoz Abukilab to investigate the ecology and the economic importance of the vegetation cover. Transects Reading and Interview were used for compiling data. Description of the plant species and their distribution were recorded.Tummam (Panicum turgidum), Marekh (Leptadenia pyrotechnica) were the most dominant species in the study area they form 33.49%, 5.48% respectively. The three sites had more than 50% vegetation cover. Non existences of some species were agents. attributed to over-grazing, drought, and other ‫‪the areas play a vital role in combating desertification, fixing‬‬ ‫.‪sand dunes and decreasing erosion‬‬ ‫‪On the other hand these plants represent fodder for livestock‬‬ ‫‪during the drought periods.
