About Vachellia sieberiana (DC.) Kyal. & Boatwr.
Nomenclature and Native Range
Vachellia sieberiana, which was known as Acacia sieberiana until recently, is a tree native to southern Africa that has been introduced into Pakistan.
Size Characteristics
This tree reaches a height between 3 and 25 metres, with a trunk diameter from 0.6 to 1.8 metres.
Conservation Status
It is not listed as a threatened species. In its natural range, Vachellia sieberiana is widespread and faces no threats.
Herbivory
It is browsed by livestock and game animals including elephants and giraffes.
General Human Uses
Vachellia sieberiana is primarily valued as a source of forage, medicine, and wood.
Bark Fibre Use
Its inner bark provides fibre, which is used for purposes such as stringing beads.
Gum Edibility
Its gum is edible.
Seed Dispersal
Both livestock and game browse the tree and feed on its fallen pods, spreading viable seeds through their dung.
Apiculture Value
The tree's flowers are good forage for bees, and beekeepers place hives directly on the trees to use this resource.
Anti-Herbivory Chemical Defenses
When the tree is heavily browsed, its leaves commonly release toxic chemical compounds. Some of these compounds can release hydrogen cyanide when ingested, which can be lethal to cattle.
Dry Season Forage Value
Fallen pods and foliage of the tree provide critical lifesaving forage during dry seasons.
Additional Gum Uses
The tree's gum is used as food, an adhesive, and an ingredient in ink production.

Stomach-Ache Root Remedy
As cited from the World AgroForestry Centre, a decoction of the root is taken as a remedy for stomach-ache.
Multi-Part Medicinal Uses
The bark, leaves, and gums are used to treat tapeworm, bilharzia, haemorrhage, orchitis, colds, diarrhoea, gonorrhoea, kidney problems, syphilis, ophthalmia, rheumatism, and disorders of the circulatory system, and are also used as an astringent.
