Name: Sudano-Sahelian Treed Savanna Macrogroup
Reference: NatureServe Biotics 2019
Description: In the transition belt known as the Sudan-Sahel region, the southernmost part is the moister with 5-25% tree cover, >5 m high of <i>Prosopis africana, Vitellaria paradoxa, Parkia biglobosa, Acacia seyal</i>, and <i>Faidherbia albida</i>. This macrogroup covers the treed savanna communities that grow in the Sudano-Sahelian and Sudano-Guinean areas which have an average annual rainfall of 500-1000 mm between May-June and September-October. These savannas undergo an annual dry period of 6-8 months and are subject to strong water stresses that vary in time and space. The transitions between treed, shrub and grass savannas are also due to landscape position, soils and history of land use. The soil capacity to retain moisture determines the density of the woody cover, as well as the density and composition of the herbaceous cover. Vertisols and ferrugineous soils are moister and vary between 20 and 50% of woody cover. In these conditions, the grasses that thrive and dominate are <i>Loudetia togoensis, Andropogon pseudapricus, Sporobolus festivus, Panicum laetum, Fimbristylis hispidula</i>, and <i>Spermacoce filifolia</i>.
