%X We carried out this research at Abu-Gaddaf Natural Forest Reserve (ANFR) which is located east of Blue Nile River, in Blue Nile State, Sudan. It aims at exploring tree composition assessing their diversity indices, and ecological importance values. For survey of types and estimation of density of tree species in the forest, we randomly distributed 97 circular sample plots (0.1 hectare (ha)). In each sample plot we identified all trees to the species level, recorded their frequencies and computed species diversity and importance value indices (IVI). A total of 13 tree species, which belong to 12 genera and nine families, were identified in the tree layer of the forest. Mean tree density in ANFR was 116 trees/ha, composed mainly of <em>Boswellia papyrifera</em> (Del.) Hochst. (48), followed by <em>Combretum hartmannianu</em> (19) and <em>Lannea fruticosa</em> (18). Fabaceae was the most common family followed by Combretaceae and Malvaceae. <em>B. papyrifera</em> Delile Hochst was the most abundant while <em>Acacia seyal</em> was the least abundant species. Species richness (<em>R</em> = 1.71), evenness (<em>E</em> = 0.69), dominance (0.24) indices and Simpson¡¯s Index of Diversity (<em>D'</em> = 0.76) suggest a moderate diversity, moderate numbers of individuals in each species and a moderate community stability. The research provides empirical results on diversity and ecological importance value of species, signifies the urging need to safeguard threatened species and to prioritize them for conservation, as well as the need to promote management of abundant species to provide multiple forest ecosystem services.
