Natural regeneration of Heglig [Balanites aegyptiaca (Del.)] in the dry region of Sudan

Balanites aegyptiaca is a promising widely distributed tree of high economic, social, and environmental value. However, its existence is threatened. The objective of this study was to assess the natural regeneration of B. aegyptiaca in the dryland of Sudan. Natural regeneration of B. aegyptiaca was monitored in the field at different sites, immediately after the rainy season. Those sites were abandoned agricultural farms, natural forests, vicinity of villages, valleys (seasonal water courses) and karab (eroded site). Random samples with 50 m in diameter each were laid on the northern, middle and southern skirt of various locations in each of the site. Height and diameter of sample trees were recorded. Any B. aegyptiaca plant measuring 2.5 cm and less in diameter and height 1.3 m or below was considered as seedling. Results revealed that the natural regeneration of B. aegyptiaca was continuous in all sites except in the village vicinity. The stocking density was more than fair in most sites, specially the abandoned agricultural farm (1375 plant/ha), but scanty along valley meander and banks (135 -290 plant/ha). It was concluded that if attention could be given to conservation and management of B. aegyptiaca stands, the tree species would survive as the natural regeneration is abundant. A planting programme is therefore not required.
