 The drier parts are dominated by the African kino tree and "Combretum glutinosum", while the gallery forests beside rivers and streams (many of which dry up seasonally) are largely formed from "Erythrophleum guineense" and "Pseudospondias microcarpa", interspersed with palms and bamboo clumps.Depressions in the ground fill with water in the rainy season and support a wide range of aquatic vegetation.In the coastal zone of Niayes, a coastal strip of land between Dakar and Saint Louis where a line of lakes lie behind the coastal sand dunes, the predominant vegetation is the African oil-palm, along with the African mesquite and Cape fig.
