Title: Adansonia digitata: Structure, Density, Important Uses, and Potential Habitat in Blue Nile and Sinnar States, Sudan
Author: Omer, Ali Haroon Ali
Abstract: The present study collected information on Baobab species population in Blue Nile and Sinnar States, Sudan. The objective of the study was to investigate and describe natural regeneration status, density, diameter-class, and height distribution of the species under selected land use categories (village, natural forest, and agricultural fields). Random transects were used for sampling Baobab components along the different land uses. Diameter, height and geographical coordinates of all trees were measured in each sample transect. The study also considered the suitability of the study area as habitat for Baobab. Maximum Entropy approach was used for habitat modeling. The Results showed that there were significant differences between different land use systems for Baobab diameter and height class distribution curves. All land uses showed inversed J-shape distribution curveindicating good recruitment rate. The statistical tests showed highly significant difference (p<0.005) in Baobab density among land uses. Baobab density in the field was very critical (0.11tree/ ha). Percentage of seedlings and juveniles to adult trees were highest in the field (64% of seedling), followed by village (48 %), while Forest tends to have lowest percentage (19 %). Seeds and fruits collection by people and cattle browsing claimed to be the main reasons for the low seedling percentage in the forest. Fruits, leaves, and bark are the main parts of the Baobab used. However, the fruits (51%) were the most important part of tree, followed by the leaves (34%), and the bark (15%). Uses of Baobab was highest for food (44%) followed by soft drinks (39%) and medicinal uses (17%). Almost two thirds of the total area is predicted to be a suitable habitat for Baobab trees; while 20 % of the study area has been classified as highly suitable habitat. The study concluded thatBaobab population has stable trend and good recruitment in the study area.The resultsindicate that the study area has high potentiality for cultivation of Baobab. Further investigations are recommended in relation to habitat suitability, active protection of Baobab seedling, and rising of local community awareness about sustainable Baobab utilization.
