Impact of soil types on vegetation cover (herbaceous, grasses &trees) and rangelands management process in south kordofan state, sudan.

This research was conducted in South Kordofan State in general and the vegetation measurements were focusing at Eldebeibat area for the two rainy seasons (2013 – 2014). It aimed to assess the impact of soil types on vegetation cover (herbaceous, grasses and trees). According to soil types, the study area divided into the three sites namely: sandy, clay and gardud. To determine the vegetation cover (herbaceous and grasses) measurements, the Parker Loop Methods [1] were used to obtain plant composition%, relative plant composition% and Quadrat Method was used to determine frequency and plant cover%. The Nearest Individual Method [2] was used to measure the trees density and relative trees density. The socio-economic survey for sedentary and the nomadic families to identify the plants species the three sites was done. Eight transects (100m length) were laid out randomly in each site and then ten quadrats (1x1m) were taken along each transect and vegetation measurements were taken at 10 m interval. Each quadrat represented point to identify the nearest species of trees. The standard equations were used to calculate parameters of vegetation measurements and data of socio – economic calculated to obtain frequency and percentage. The results showed there were variations between the three sites in vegetation cover. Sandy had the highest plant composition, compared to the clay and gardud sites. Nevertheless, the three sites recorded different plant cover% and the three sites were dominated by different species in both understory and overstory respectively. Sandy dominated by Zornia glochidiata and Guiera senegalensis, clay dominated by Schoenfeldia gracilis and Acacia oerfota and gardud was dominated by Vossia cuspidata and Acacia mellifera. The pastoralists confirmed the three sites dominated with different species. Schoenfeldia gracilis considered dominant species in the clay site, Sandy sites was dominated by Zornia glochidiata , clay dominated by Shoenfeldia gracilis and gardud dominated by Eragrostis spp and sedentary communities through investigated about plants species occurrence around their villages were different such as Zornia glochidiata, Eragrostis spp and Schoenfeldia gracilis.
