Apple-ring acacia

Faidherbia albida

''Faidherbia'' is a genus of leguminous plants containing one species, ''Faidherbia albida'', native to Africa and the Middle East. The species was formerly widely included in the genus ''Acacia'' as ''Acacia albida''. It has also been introduced to Pakistan and India. Common names for it include apple-ring acacia , ana tree, balanzan tree and winter thorn.

It is a thorny tree growing up 6–30 m tall and 2 m in trunk diameter. Its deep-penetrating tap root makes it highly resistant to drought. The bark is grey, and fissured when old. There are 11,000 seeds/kg. ''Faidherbia albida'' is not listed as being a threatened species.

It grows in areas with 250–600 mm of rain per year.

''Faiderbia albida'' is known in the Bambara language as ''balanzan'' and is the official tree of the city of Segou on the Niger River in central Mali. According to legend, Segou is home to 4,444 ''balanzan'' trees, plus one mysterious "missing tree" the location of which cannot be identified.

In Serer and some of the Cangin languages, it is called ''Saas''. Saas figures prominently in the creation myth of the Serer people. According to their creation myth, it is the tree of life and fertility.

The northernmost natural populations are found in relict groves in Israel . All of the trees in a given grove are genetically identical and seem to have multiplied by vegetative reproduction only, for thousands of years.

''Faidherbia albida'' is important in the Sahel for raising bees, since its flowers provide bee forage at the close of the rainy season, when most other local plants do not.

The seed pods are important for raising livestock, are used as camel fodder in Nigeria, and are relished by elephant, antelope, buffalo, baboons and various browsers and grazers, though strangely ignored by warthog and zebra.

The wood is used for canoes, mortars, and pestles and the bark is pounded in Nigeria and used as a packing material on pack animals. The wood has a density of about 560 kg/m3 at a water content of 12%. The energy value of the wood as fuel is 19.741 kJ/kg.

Ashes of the wood are used in making soap and as a depilatory and tanning agent for hides. The wood is used for carving; the thorny branches useful for a natural barbed fence. Pods and foliage are highly regarded as livestock fodder. Some 90% of Senegalese farmers interviewed by Felker collected, stored, and rationed Acacia alba pods to livestock. Zimbabweans use the pods to stupefy fish. Humans eat the boiled seeds in times of scarcity in Zimbabwe.

It is also used for nitrogen fixation, erosion control for crops, for food, drink and medicine. Unlike most other trees, it sheds its leaves in the rainy season; for this reason, it is highly valued in agroforestry as it can grow among field crops without shading them. The leaves from this legume tree are high in nitrogen, and can double yields in maize crops when added to the soil.The extract is used to treat ocular infections in farm animals.
