Wooded and open grasslands are widespread. The ground is thickly covered by perennial grasses, including species of Andropogon, Hyparrhenia, and Loudetia. Trees, including Annona senegalensis, Burkea africana, Combretum collinum, Hymenocardia acida, Parinari curatellifolia, Stereospermum kunthianum, and species of Vitex and Strychnos, form open-canopied woodlands or are scattered in grassy savannas. Frequent human-caused fires have allowed grasslands to spread into areas formerly covered with forest or woodland.
