Several locations were sampled in Nouakchott and Rosso, which are not plotted individually on the map due to scale. The map was created with GADM data 3.6 (https://gadm.org/download_world.html) and the FAO Global Ecological Zones (GEZ) (https://data.apps.fao.org/map/catalog/srv/ger/catalog.search#/metadata/2fb209d0-fd34-4e5e-a3d8-a13c241eb61b).
