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.

Species Card Details

Importance:

The Euphorbiaceae family is facing increasing threats in southern Africa due to poaching for illegal trade, with over 30 species currently classified as threatened and another 30 species either lacking sufficient data or yet to be evaluated. This highlights the urgent need for targeted conservation efforts to prevent further decline and avert critical risk.
