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.

White Milkwood

Importance:
The white milkwood is a protected South African tree found along the southern and eastern coasts, where it dominates parts of the Western Cape’s coastal forests. Its coppicing growth form may result in low genetic variability in isolated populations, making them vulnerable to rapid climatic change and highlighting the need for population genetic studies. The species also holds strong cultural significance, with historic gathering trees such as the “Post Office Tree” in Mossel Bay and the “Treaty Tree” in Woodstock, Cape Town.
