Invasive species
Dichrostachys cinerea is considered to be an invasive species, notably through bush encroachment, the ecological process in which a grass-dominated community is changed into a woody community. Encroachment is the result of overgrazing and is attributed to the ability of Dichrostachys cinerea to regenerate from seeds and root buds. Grazing by goats may help to control its development (Ecocrop, 2011; Yayneshet et al., 2008a; Tolsma et al., 1987). In the West Indies, Dichrostachys cinerea has been responsible for the invasion of rangelands and has caused significant agricultural production losses. It is now considered a risk in places with similar climates such as Hawaii or South America (SANBI, 2011).
Soil improver and stabilizer
The roots fix atmospheric nitrogen and the leaves are frequently used as a green manure. Dichrostachys cinerea is widely used for sand dune stabilization and soil conservation. It is useful for revegetation and intercropping (Ecocrop, 2011).
Other uses
Dichrostachys cinerea is also as an ornamental plant and makes efficient defensive live fences (FAO, 2011).
