Acacia tortilis is an N fixing species and thus a soil improver. It is used in erosion control since it is able to grow quickly and stabilize shifting sand dunes or hillslopes. It is used to make shelterbelts in India. It is also an afforestation species (FAO, 1985). However, introducing the tree to more humid areas, where grazing and firewood are in adequate supply, is not recommended, as it can grow out of control and become a nuisance (Ecocrop, 2009).
