Impact of Herder Activities on Rangelands at Semi Arid Zone of North Darfur State, Sudan

The research work was conducted over a two years' period of 2015 and 2016 at three sites of Alfashir locality Ummarahik 25km north of Alfashir, Fashar in eastern part of Alfashir about 5km and Berka 30km west of Alfashir , Western Sudan in semi arid zone. The objectives were to assess the effect of human activities and animal grazing on rangelands, specific objectives were to assess grazing intensity and tree shrub in the study area. In the first season the results showed that the higher number of quadrates subjected to grazing were at level II with the percentage of 55.56 for Ummarahik, and percent of 44.44 and 38.89 at level I grazing for Berka and Fashar. In Berka there was 5.56 for no grazing, and 16.67 in Fashar. Also the result showed there was 16.67 at level IV in Berka and Ummarahik and 11.11 in Fashar. In the second season the result showed that the percent of no grazing were 22.22 and 16.76 in Berka and Fashar respectively, also the result showed there was no grazing at level IV in Berka and Ummarahik. Berka had highest tree shrub density which scored 32 and 23 tree ha at season 2015 and 2016 respectively. Fashar scored lowest density 7 and 5 tree ha.Balaniteaegyptiaca was the dominant tree species in the study area, while other species were less. The study concluded that unwise utilization and exploitation of the rangelands particularly by man causes range deterioration and serious reduction in range production, so, the study suggested that improvement and rehabilitation should be done. Further research work is needed to assess rangelands at different ecological zones in North Darfur State. Mohamed Almontasir A. M.
