Vegetation Common tree species are shea trees (Vitellaria paradoxa, Sapotaceae), Parkia biglobosa (Mimosacées), Balanites aegyptiaca (Balanitaceae), and Piliostigma thonningii (Fabaceae - Caesalpinioideae). Woodland is generally observed in old fallow. In more recent fallow, a savannah occurs frequently. Along the rivers, the vegetation is a gallery forest. A mosaic of shrub is observed on hills where combretum occur frequently. The grass layer is dominated by tall, perennial grass species such as Andropogon gayanus, Loudetiopsis kerstingii, Cymbopogon schoenanthus , Andropogon pseudapricus, Pennisetum pedicellatum.
Soil Type
  • •

    Tropical eutrophic brown soils on clay material. The chemical potential is high. They are the best soils in the country;

  • •

    Tropical leached ferruginous soils on sandy material, these are soils with low agronomic value, spatially dispersed;

  • •

    Ferrallitic soils on sandy-clayey material: these are permeable, acidic soils with low chemical potential;

  • •

    Mineral hydromorphic and pseudogley soils on varied texture material. These soils are favourable to many crops; their chemical potential is average;

  • •

    Raw mineral soils associated with slightly developed soils. Their agronomic interest is low or zero. These are mainly land reserved for grazing;

  • •

    Vertisoils and eutrophic brown soils. These are average to high agronomic value soils, suitable for all crops in the region. They can be easily improved;

  • •

    Tropical ferruginous soils. They have a very low agronomic value and can only be used for undemanding subsistence crops such as fonio and millet;

  • •

    Hydromorphic soils, located in lowlands and flooding areas. These are heavy, but with high agronomic value. They are excellent lands for gardening.
