Large Mammals: Giraffe browse on leaves and young shoots. Elephants feed on leaves and branches. Bushbuck regularly browse the foliage. Nyala feed on leaves, especially in riparian zones.
Small Mammals: Rodents use fallen leaves and bark for nesting material. Bats roost in dense canopy and feed on insects attracted to flowers.
Reptiles: Geckos & lizards shelter in bark crevices and feed on insects around the tree.
Flowers provide nectar and pollen to a wide range of pollinators and flower feeders.
Fruits are dispersed by wind and animals.

Semi-hardwood cuttings root moderately well.
Traditional Uses:
Wood:
General-purpose timber: The wood is coarse-grained, tough, and easy to work with. It has a yellow-brown hue and is used for furniture, ornaments, rafters and beams in buildings, and for household items such as grain mortars, cattle troughs, and utensils. Firewood: Though not top-tier, it serves as average-quality fuel. Varnish production: Damaged stems exude a sticky, elastic gum used as a non-cracking varnish for pottery and furniture. Dyeing & tanning: Roots yield a rich, dark brown dye used in tanneries to tan hides.
Other Cultural Uses:
Gum as food adulterant: In some communities, the gum is added to food (not recommended). Ornamental value: Dried fruits are used in floral arrangements and as decorative items in homes.
Shade & landscaping: Planted as a shade tree in gardens and streets due to its beautiful seasonal foliage and hardy nature.
Animal care: Seeds are used as an anthelmintic for dogs (this is not advised as it works due to the toxicity of the seeds).
Traditional varnish: Gum from stems is applied to pottery to seal cracks and prevent breakage
Traditional Medicinal Uses: Venereal diseases – Leaf and root infusions used as treatment and prophylactic. Infertility -Bark decoctions traditionally consumed to improve fertility. Labour pains & childbirth: Seed and root decoctions taken during pregnancy to ease delivery. Abdominal pain & constipation: Leaf infusions and root decoctions used as purgatives. Coughs & respiratory issues: Bark and root preparations used to relieve symptoms. Leprosy & skin sores: Bark and root decoctions applied or consumed.
Caution: Several of the abovementioned practices have been linked to severe adverse effects including vomiting and confusion. The use of the plant in a cultural setting illustrates how potentially toxic plants are commonly used, and without adequate medical training users are often ill-equipped to recognise the toxic effects of traditional remedies.
Bioactive Properties: Antibacterial & antifungal -effective against Staphylococcus aureus, Candida albicans, and others. Anti-inflammatory & antioxidant– High phenolic and flavonoid content. Cytotoxic & apoptotic possible cancer-related applications.
