The main objectives ofthis study were to detecting the land use and land cover change LULC, usingremote sensing techniques, then identify the reasons for rangeland and treecover degradation in El Rawashda Forest, Gadarif State, Sudan. The study hasconducted field experiment developed on an area of 20 feddans that was affectedby deterioration in the forest and to assess the best method for rehabilitationof the vegetation cover in the area of study. The experimental area was dividedinto 5 blocks; each block consisted of 4 treatments: grass seeds and TalihAcacia seyal var. seyal; sowing seeds just before autumn, sowing seeds afterdisc ploughing, sowing seeds using water harvesting technique and control noseeding. In the present study an attempt has been made to analyze and monitorthe LULC changes using multi‐temporal Landsat datadeterioration in the forest and toassess the best method for restoration of the vegetation. In the present study,an attempt has been made to analyze and monitor the LULC changes using multi‐temporal Landsat data for years1984, 1994 and 2013. LULC grades in the classification scheme are: Trees, Mechanized Rain-fed Agriculture MRA,Grasses and Bare land. Individual classifications based on maximum likelihoodof algorithm were used and the results showed a significant that extensivechange of LULC patterns has occurred in all decades in the study area. Theresults also show Trees class was decreased, while MRA, Grasses and Bare landwere increased. The seeding of the forage and Talih seeds after disc plowinggave the best results compared to the other treatments, followed by forage andTalih seed sowing under the water harvesting technique and broadcasting offorage and Talih seeds and finally the control.
