Forests in the aridlands of Sudan are distinctive in nature and require special attention due to the great role they play as a first and last line of defense against south-ward desertification.Thus,to determine their conservative and protective needs based on current conditions in the Wad Al-Bashir Forest(WF),toward ensuring sustainable forest resources in these areas,we used a systematic field survey,existing and available documents review and key informant interviews(KII),to collect data from 08 December 2017 to 15 May 2018.A severe depletion and changes in the forest tree cover and composition were found during the field sur-vey,where species such as Balanitis aegyptiaca is threatened and invasive species(e.g.,Acacia nubica)have started to dominate.Reviewed documents have credited illegal cut-ting and agricultural activities for the changes in the for-est status,whereas the KII indicated that past and current forest conservative and protective practices(CPPs),where forest clearance for agricultural,grazing,pests and disease control,were not given a deserved consideration as they relate to tree cutting and reforestation practices.Likewise,negligence of the needs of those who depend on the forest and inadequate funds have constrained implementation of some CPPs.Accordingly,on the basis of the results of this study,we recommend that CPPs associated with agriculture,grazing,forest fire,pest and disease control should be a top priority concern of forest authorities.Better financial sup-port,which could be enriched by involving governmental and non-governmental organizations,is also needed to boost CPPs in the WF.Invasive species also need to be cleared and replaced by trees such as A.senegal and B.aegyptiaca that are of economic and environmental value.
