Assessment of Rangelands in Protected and Grazed areas at Zalingei area, Central Darfur State, Sudan

The study was conducted at Zalingei areas, Central Darfur State, Sudan. During rainy season in 2018 to assess the vegetation attributes in the protected and grazed sites at rangelands. The vegetation attributes which were measured by Parker Loop Method included plant composition%, plant relative composition%. Quadrat Method was used to determine frequency% and biomass production. Carrying Capacity was calculated depend on biomass production. The standard equations were used to analyse the data of vegetation attributes which were mentioned in part (2). The protected site was showed higher values of plant litters and bare soil respectively (24.83 and 23.16%) than grazed site (19.5% and 15.16%). The dominant species in the protected site most of them belong to grasses, included Aristida fanculata, Eragrostis spp, Aristida mutablis, Scheonfeldia gracilis and Zornia glochidiata and the dominant species in the grazed area included Aristida fanculataI, Zornia glochidiata, Oldenlandia senegalensis, Dactyloctenium aegyptium and Scheonfeldia gracilis, the dominant species in the protected area most of them are grasses. In the grazed area most of dominant species were forbs and considered unpalatable for livestock in the study area. The research recommended the protection of rangelands has benefits to rest plants from grazing process, particularly at early rainy season.
