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:

Searsia lancea is a hardy, fast-growing indigenous tree important for dryland ecosystems and urban greening due to its resilience. Despite its ecological value and widespread use, genomic resources are lacking, and genome sequencing would support conservation, restoration, and climate adaptation research.
