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.

Distribution:

Pearson's Aloe is highly localised, occurring in the north-western corner of South Africa and the southern parts of Namibia in the Lüderitz district. It has a narrow distribution that is limited to the area between Kuboes in the South African Richtersveld National Park and the mining town of Rosh Pinah in southern Namibia. Its distribution falls within, and contributes to the biodiversity of, the Gariep Centre of Plant Endemism.

Pearson's Aloe

Species Card Details

Importance:

Rising temperatures and prolonged drought in the Richtersveld (2015–2020) caused major die-offs of Pearson's Aloe, which has very low recruitment and grows extremely slowly. Overgrazing has intensified the decline, as livestock and wildlife now feed on this species due to the scarcity of other plants. Although valued medicinally and horticulturally, it remains difficult to cultivate.
