The Umbrella Thorn Acacia is a thorny leguminous tree with the
classic, umbrella-shaped canopy associated with thorn trees. It is usually
about 4-8 m high, but it can reach 20 m. The crown is dense, broad, spreading and
flat-topped. Leaves are compound and the leaflets (6-22 pairs) are very small
(1-4 mm long x 0.6-1 mm broad), glabrous to pubescent. Flowers are white, cream
or yellow, and highly aromatic. Fruit is a characteristic twisted brown pod,
hence the epithet “tortilis”. Leaves are used as a fodder. Fruits are more
nutritious if ground. Trees can survive heavy browsing. The umbrella thorn
is native to arid and semi-arid areas of Africa and the Middle-East. It grows
well on alkaline sandy or rocky soils. It is tolerant to severe drought due to
its deep taproot system. It tolerates strong salinity and seasonal
waterlogging. It withstands wide temperature variations (0°C to 50°C). It occurs
in deciduous woodland, thornveld and bushveld. It is found from sand dunes and
rocky scarps to alluvial valley bottoms.
The timber is used for fence posts, firewood, furniture and wagon
wheels. The prolific pods make good fodder for desert grazers and the foliage
is also palatable, Acacia tortilis being one of the major dry season
fodder trees of the Sahara-Sahelian belt. Many bird species take advantage of
the protection it offers and build their nests in the canopy. Bark is used for
string in Tanzania. Gum is used as gum arabic, said to be edible. It is the
tree most recommended for reclaiming dunes in India and Africa. The thorny
branches are used to erect temporary cages and pens. Bark is said to be a good
source of tannin. Africans once strung the pods into necklaces. Senegalese use
the roots for spear shafts; Lake Chad natives use the stems for fish spears.
African nomads often use the flexible roots for frameworks of their temporary
shelters. The pods and leaves are highly nutritious. Vervet monkeys and baboons
eat young green pods; other animals eat those which have fallen to the ground.
