Abstract
The Adansonia digitata (L.) locally known as the Baobab or Tebaldi tree is an important multi-purpose species in the dry lands of the Sudan. It has been underutilized, inaccessible and neglected from many potential applications and uses in the country. Being one of the species producing countries, Sudan incorporates the Baobab under different land use patterns and locations such as agricultural lands, outcrops, grazing lands, villages and homes. The current study was conducted in two years 2014 and 2015, with special focus on the factors that influence the regeneration of the Baobab in two sites namely Elkhoway and Eldudia in West Kordofan State. The two areas were intentionally selected as they are accessible and typical example of sites highly populated with the Baobab. Primary data were collected from systematically located twenty strip sample plots each was 1 Km long and 50 m wide. In each sample plot all Baobab trees, saplings and seedlings were counted and measured for diameter at breast height. Secondary data were obtained from relevant sources, references and pertinent institutions. Data were analyzed using R statistics software as well as Statistical Packages for Social Sciences (SPSS), where descriptive analysis was applied. The average diameter at breast height of Baobab tree was measured as 214.1 cm and 236.3 cm for Eldudia and Elkhoway, respectively. The two sites were significantly different (p ≤ 5) with respect to minimum diameter at breast height, which was found as 57.3 cm for Eldudia and 114.6 cm in case of Elkhoway site. The main findings revealed that past recurrent drought spells, wind and climate change had negative impacts on population density of the Baobab in the study area. Human practices and overgrazing were considered as the most affecting factors having adverse impacts on regeneration of the Baobab. Overgrazing, frequent floods and consequential erosions were the top listed factors threatening Baobab regeneration. It was concluded that the Baobab regeneration in West Kordofan State has been negatively affected, which case necessitated urgent intervention. The study recommended development of strategies that enable interventions aspiring at achieving proper management, conservation and rehabilitation as well as successful regeneration of the Baobab populations in the area.
