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.

Euphorbia mauritanica

Yellow milk bush

Species Card Details

Importance:

The yellow milk bush a is toxic to livestock and sometimes confused with another succulent shrub used as forage, but it is valued as a drought tolerant ornamental. In southern Africa, members of the Euphorbiaceae face increasing threats from illegal trade, highlighting the need for urgent conservation.
