Abstract

This study was aimed to evaluate the diversity of shrub and tree species growing under Boswellia papyrifera tree plantation of AlGerri forest reserve in Blue Nile State. 18 systematic circular sample plots of 0.1 ha. (Radius = 17.84) with intervals of 100 m between each plot were used to collect data. A total of 13 woody species belonging to 7 families were determined in two Boswellia papyrifera plantation communities. Boswellia papyrifera dominated the woody species in all vegetation communities, followed by Combretum hartmannianum and Vachellia seyal. The Shannon diversity indexes (H) of community number one and community number two were 0.328 and 0.429 respectively. Pielous Evenness index (E) values in both communities were 0.344 and 0.429 respectively. The density of both communities was 609.1 and 309.08 plant/ha. respectively. The distribution of woody species showed that 61.54% of species were aggregated and 38.46% of species were randomly distributed. Cluster analysis based on the Bray-Curtis single linkage was used to assess the similarity between woody species composition across the 18 sampled plots.
