relict river valley and region of interior northern Senegal. It lies south of the fertile valley of the Sénégal River and the Fouta region and east of the peanut (groundnut) basin of the western plains. Ferlo is a dry, featureless expanse of savanna with only a few small scattered settlements. Its inhabitants are the Fulani (Fulbe) people, who cultivate peanuts near deep wells or seasonal streams in the south and practice irrigation and transhumance in the north. Ferlo-North and Ferlo-South faunal reserves are located in this area.
