Abstract


This study evaluated woody tree vegetation in Bara locality as
a part of Gum Arabic belt that was affected by drought, with special
reference to A. Senegal. It compared the existing cover with past
vegetation in terms of tree density and species composition. The locality
was divided into four sections and two villages were taken randomly from
each section. A vegetation survey was carried out around each village to
identify tree species, number of trees per ha and mode of regeneration and
maturity stage of A. Senegal trees. The results showed that the same tree
species in Bara Locality were maintained while changes in relative
densities were observed especially for A. Senegal, which decreased to 2%
as compared with 31% in 1995. The dominant tree species were Acacia
tortilis followed by Leptadenia pyrotechnica, Calotropis procera,
Balanites aegyptiaca, Faidherbia albida, Ziziphus spina-christi and lastly
A. Senegal. The dominant mode of A. Senegal regeneration was natural
regeneration by seeds. The study recommended artificial regeneration
plantation of A. Senegal to supplement the natural one and to increase the
awareness of local people with its direct and indirect benefits.
