Importance:

Sclerocarya birrea is an economically and culturally important African tree, valued for products such as Amarula Cream Liqueur, cosmetic oil, and its traditional medicinal uses, while also supporting rural livelihoods. Its drought tolerant and deep rooting system make it important in agroforestry and ecosystem resilience. Sequencing its genome will improve understanding of its biology, support conservation and breeding efforts, and enhance sustainable commercial development.

Karoo num-num

Species Card Details

Importance:

Karoo num-nums are evergreen and provide food and shelter for a wide range of wildlife. They are wind resistant and moderately drought-tolerant, but susceptible to frost. They are cultivated for ornamental use as shrubs and hedges with starry white flowers and bright red edible fruit. The roots have been used medicinally to treat toothache. The num-num is also used in traditional Swazi ceremonies.
