Name: Sudano-Sahelian Herbaceous Savanna Macrogroup
Reference: NatureServe Biotics 2019
Description: This macrogroup corresponds to the Sahel proper, mostly distributed in Senegal, Mauritania, Mali, Burkina Faso, Niger, and Chad. Mean annual precipitation is 200-400 mm. Although precipitation varies with latitude and local conditions, it is generally restricted to a period of 3-5 months. Storms are frequently violent in nature and the rain is often erratically distributed, both in terms of when and where it falls, with variability increasing from south to north within the Sahel. Most of the Sahel lies below 400 m in elevation. Soils vary from silty to weakly developed sandy soils on shifting and stabilized sands in the north. The vegetation is a very open savanna where grasses dominate, with a woody cover of &lt;10%. Annuals such as <i>Aristida adscensionis, Aristida funiculata, Panicum laetum</i>, and <i>Schoenefeldia gracilis</i> are found on silty soils; <i>Aristida mutabilis, Cenchrus biflorus, Tribulus terrestris</i>, and <i>Pennisetum pedicellatum</i> are found on sandy soils. Common woody species are <i>Acacia ehrenbergiana, Acacia laeta, Acacia nilotica, Acacia senegal, Acacia tortilis, Balanites aegyptiacus, Maerua crassifolia, Salvadora persica</i>, and <i>Ziziphus mauritiana</i>.
