“…Kokwaro (Anacardiaceae), known as marula in English, is a common tree species in the semi-arid, deciduous savannas of sub-Saharan Africa Nghitoolwa et al, 2003;Viljoen et al, 2008;Mokgolodi et al, 2011). Due to its drought resistance and tolerance of poor soils, S. birrea grows well under dry and hot conditions even with a mean annual total rainfall as low as 200 mm (Nghitoolwa et al, 2003;Mokgolodi et al, 2011). As an important edible, medicinal, and economic tree species of high ecological, cultural, and commercial value, S. birrea is used widely by local peoples Wynberg et al, 2002;Nghitoolwa et al, 2003;Mokgolodi et al, 2011).…”
