Acacia mellifera is a common thorn tree in Africa. The name mellifera refers to its sweet-smelling blossoms and honey. Its lumber turns pitch black when oiled. Common names of the tree include Blackthorn and Swarthaak (Afrikaans). It is listed as being not threatened.
Acacia mellifera is a widely occurring shrub on rangelands throughout the savannah in western, eastern and southern Africa, as well as on the Arabian Peninsula. A prototype ecoregion is the Kalahari xeric savanna of southern Africa. The species is found preferentially on rocky soils and along seasonal riparian zones, typically mixed with other trees. If overgrazing by non-native game is encouraged, and if aggressive fire suppression is used, it forms dense, impenetrable thickets, two to three metres high. Not only does this outcome degrade good grazing land, but many native game species are significantly hindered by such thickets.
