Abstract
The research work was conducted at Alfashir locality for two consecutive seasons of 2012 and 2013 at three sites (Ummarahik 25km north of Alfashir, Fashar in eastern part of Alfashir about 5km and Berka 30km west of Alfashir) in semi-arid zone of North Darfur State. The aims of this study were to assess range components and species composition. Measurements of %plant, %litter, %bare soil, %feces or rocks and %species composition were assessed. The results showed the percentage of range components in different sites for two seasons; average plant composition was 52.33 and 68.04 for seasons 2012 and 2013, the average of %litter was (10.82%, 6.52%), bare soil (27.74%, 16.18%) and feces was (9.11, 9.26) for both seasons respectively. The species of highest composition was Aristida sp (26.75%, 26.56%) while species of Sesamum alatum had lowest percent (3.40%, 3.21%) for the seasons 2012 and 2013 respectively.The study concluded that unwise utilization and exploitation of the rangelands particularly by man causes range deterioration and serious reduction in range production in both quantity and quality, so, the study suggested that improvement and rehabilitation such lands rangelands should be done. Further research work is needed to assess rangeland attributes across different ecological zones in North Darfur State.
