Various naturally occurring tree species can be used which may also provide berries, fruits and nuts or have medicinal qualities. In Niger, commonly used species include: "Strychnos spinosa", "Balanites aegyptiaca", "Boscia senegalensis", "Ziziphus" spp., "Annona senegalensis", "Poupartia birrea" and "Faidherbia albida". However, the most important determinants are whatever species are locally available, their ability to re-sprout after cutting, and the value local people place on those species.
