The reflooding of the Ferlo Valley since 1988 after 32 years of drying up has caused progressive growth of aquatic plants. 103 woody and herbaceous plants falling into 81 genera and 38 families were identified in the Valley. Analysis of the vegetation using the transect technique and the Braun Blanquet method helped to establish the floristic composition of 7 aquatic and semi aquatic plants groups. Typha domingensis and Pistia stratiotes are dominant in the aquatic miieu whereas Tamarix senegalensis plant groups were frequently found in the flood plain, indicating that the tidal range is important and soil salinity was still high.
