In the 2000s, molecular phylogenetic studies resulted in the controversial transfer of many Acacia species into the genera Vachellia, Senegalia, Mariosousa and Acaciella, with only Australian species remaining the Acacia genus (Kyalangalilwa et al., 2013). The tree has also been used for raft-making and fencing. The leaves are alternate, pedunculated, bipinnate, bearing 2-7 pairs of primary pinnae each bearing 5-15 (-27) pairs of leaflets. It is well suited for dry climates with little rainfall. In spring, the tree blooms with an abundance of fragrant, yellow flower clusters that resemble pompoms. Alternatively, dried leaves can be ground and used in home based or commercial rations (Mapiye et al., 2011). Acacia karroo is a pioneering species prone to be responsible for bush encroachment in grasslands and farming land in South Africa. Sweet thorn is very tolerant of cold and resistant to frost down to -10°C, which may cause defoliation but does not kill the trees. In the Molopo area of South Africa, sweet thorn encroachment may have reduced grass production by 30% (Dingaan et al., 2018). Sweet thorn provides environmental services (see Environmental impact) (Ecocrop, 2019; Fern, 2014; Orwa et al., 2009; Aubrey, 2002).

The persistent fruits have a glossy coat and contain seeds which are cherished by birds and other wildlife. This tall, semi-evergreen, native shrub or small tree has feathery, finely divided leaflets of a soft, medium green color. It is an aggressive pioneer, readily invading degraded or overgrazed areas.It competes for space, water and nutrients with pasture grasses, and may replace them (Orwa et al., 2009). There are several hybrids between these two plants that are sold in nurseries under the name “Sweet Acacia.” Sweet acacia tree is often confused with a similar plant, Acacia smallii, which is more tolerant of cold and blooms only in the spring. Condensed tannins of Acacia karroo have been reported to increasing fecal N excretion and decrease N retention in goats, which should be the result of the complexation between tannins and endogenous proteins (Mapiye et al., 2011). However, while a low tree density improves grass production, high density (>300 trees/ha) is detrimental to it (Stuart-Hill et al., 1987). Proanthocyanidins and other phenolics in, Ecocrop, 2019.

Another species of catclaw acacia (A. greggii var. Feeding Acacia karroo leaf meal at low (10%) inclusion level in the diet of pigs depressed nutrient digestibility, increased endogenous protein secretion and increased the activity of liver enzymes but did not reduce growth rate and was therefore considered as potentially feasible (Halimani et al., 2005; Halimani et al., 2007). The fibre content of Acacia karroo leaves is consistent with the fibre contents of leaves from other acacias (Brown et al., 2016; Mapiye et al., 2011; Mokoboki et al., 2005). The storage of leaf meal in bags in well-ventilated shade or storeroom until fed may improve the nutritive value of the forage but this has not been tested for Acacia karroo (Mapiye et al., 2011). Variations in the composition Acacia karroo foliage are caused by differences in populations, soil, climate, season, stage of growth, and browsing pressure. greggii and var.
