Vachellia sieberiana, until recently known as Acacia sieberiana[6][7][8] and commonly known as the paperbark thorn or paperbark acacia, is a tree native to southern Africa and introduced into Pakistan.[5] It is used in many areas for various purposes. The tree varies from 3 to 25 m in height, with a trunk diameter of 0.6 to 1.8 m.[9] It is not listed as being a threatened species.[5]
Vachellia sieberiana is valued largely as a source of forage, medicine and wood. The inner bark is a source of fibre purposes such as stringing beads[9]). The gum is edible) and both livestock and game animalsbrowse the tree and feed on the dropped pods, spreading viable seeds in their dung. The flowers of the tree make good forage for bees and bee hives are put directly in the trees to exploit the resource.[9] The leaves of the tree commonly release toxic chemical compounds when the tree has been heavily browsed, some of the compounds may release hydrogen cyanide when ingested, which may be lethal to cattle. The fallen pods and foliage can provide lifesaving forage during dry times of the year.[9]
The gum of the tree is used as food, as an adhesive, and as an ingredient in making ink.
Vachellia sieberiana is a legume and like many legumes it hosts Rhizobiumbacteria in its roots. The bacteria fix nitrogen gas from the air and, without requiring nitrogen fertilizer or soil nitrates, they convert it into nitrogen compounds necessary for plant nutrition. Ultimately, surrounding plants also benefit from the increase in available nitrogen, which means that plants such as Vachellia species are of particular ecological importance.[9]
The wood is fairly hard and it is used for furniture, handles for implements and tools for grinding grain manually.[9] The wood of V. sieberiana has a density of about 655 kg/m³.[10]
Ecology and conservationedit
This tree is widespread in its natural habitat and is not threatened. It is browsed upon by livestock and game such as elephant and giraffe.
