Name: Eastern African Semi-Desert Scrub Macrogroup
Reference: NatureServe Biotics 2019
Description: The macrogroup represents plant communities belonging to the semi-arid bushlands and thickets dominated by tree species of deciduous genera <i>Acacia</i> and <i>Commiphora</i>, where the understory consists of shrubby herbs less than 1 m high, such as <i>Acalypha, Barleria</i>, and <i>Aerva</i>. At lower elevations where rainfall is less consistent, vegetation becomes semi-desert scrubland and <i>Acacia</i> and <i>Commiphora</i> are joined by succulents of <i>Euphorbia</i> and <i>Aloe</i>, as well as grasses <i>Dactyloctenium aegyptium</i> and <i>Panicum turgidum</i>, among others. Across its distribution, the macrogroup occurs where mean annual precipitation is 100-500 mm. Following the aridity gradient, the macrogroup also includes arid shrublands/grasslands that extend inland from the Red Sea and the Gulf of Oman coasts, stretching from the Sudanese-Eritrean border, south through Ethiopia to Djibouti and northern parts of Kenya, and eastward into Somalia. Shrublands of <i>Acacia mellifera</i> and <i>Rhigozum somalense</i> dominate the basaltic lavafields, while scattered <i>Acacia tortilis, Acacia nubica</i>, and <i>Balanites racemosa</i> can be found in the sandy plains. Stands of <i>Hyphaene thebaica</i> occur in depressions and along wadis. In terms of elevation, while most is distributed between sea level and 800 m, there are hills up to 1300 m.
