Description
This study was conducted in North Kordofan State. With the objectives of identifying change in ground cover, other range attributes and the endangered plant species. The primary source of data was mainly from previous studies, while secondary data were obtained from field work using loop and transect method, personal interviews, rapid rural appraisal technique and direct observation, SPSS software was used in statistical analysis. The results indicate that there were notable changes in range composition. Percentage live plants and decreased by 17.5, while litter and rock increased by 17.9% and 0.30%. Some of the species still exist, with higher percentage such as Eragrositis termula (Banu,), Aristida sp (Gaw) and Cenchrus ciliaris (Haskaneet,) other species found in very low percentage (endangered) Chrozophora brochianna (Argassy), Aristida seibrana (Bayad), Echinocloa colonum (Difra), and Indigofra spinosa (Singid). Low rainfall savannah zone has higher percentage in live plants and lower percentage in bare soil compared to Semi-desert zone. In Semi-Desert zone the five most dominant species include: Aristida mutablis (Gaw) Eragrositis termula (Banu,), Cenchrus biflorus (Haskaneet Khishin) and Fimbristylis dichtomo (Um fisysat) they represent 70.9% of species composition. In Low-Rainfall Savannah zone the five most dominant species include: Zornia glochidiata (Shilini) Eragrositis termula (Banu,) Aristida mutablis (Gaw), Fimbristylis dichtomo (Um fisysat) and Cenchrus biflorus (Haskaneet Khishin) they represent 69%% of species composition. The important palatable endangered range species include grasses such as Blepharis linarifolia (Bugheil) Monsomia sp (Garin) Oldenlandia senegalensis (Garajob) Vigna sun-hum (Tagtaga) and Chloris gayana (kloris). Change in range attributed was clearly noticed and some important plants are being endangered, therefore the study recommends a strategy for rangeland rehabilitation to be adopted in concentration to important palatable and endangered plant species.
