Unistrata aquatic herbaceous vegetation
It is surface aquatic vegetation, unstructured and made up of floating species, not linked to a substrate and moving with the wind. The characteristic species of this vegetation are Lemna aequinotialis, Wolffiela welwitshii, Spinodela polyrrhizza, Salvinia nymphellula, Azolla
nilotica , etc. Pluristrate
aquatic herbaceous vegetation
It is made up of various associations occupying different levels of water. These associations are formed by floating, submerged unrooted, submerged and rooted species, with leaves and flowers blooming on the surface of the water, submerged and set mostly on the bottom of the waters. This category is composed mainly of Ceratophyllum demersum, Pistia stratiotes, Eicchornnia crassipes, Salvinia molesta, Hydrocharis chevalieris, Nymphea lotus, Utricularia spp., Ranalisma humile, Potamogeton octandus and Maga sp . Among these species, the
water hyacinth or Eicchornia crassipes , Salvinia molesta and water lettuce or Pistia stratioitesare invasive aquatic plants.
Semi-aquatic herbaceous vegetation
It is a vegetation that grows on mud and develops on banks or rooted on banks, it develops on surface or deep water. The plants that make it up can be found in deep waters and form floating islands during floods. This type of vegetation is characterized by Cyperus papyrus, Echinochloa spp., Phragmites mautianus, Polyum sallicifolium and Impatience spp .
Shrub and tree vegetation related to hydromorphic soils
It is made up of colonizing riparian forests (figure 10), swamp forests with a substrate that is periodically flooded or not, but without a marked period of drying and drainage during the year.
In addition, mention should be made of the alluvial valley forests and the hallophilic forests of periodically flooded saline muds of the Koukourou and Bamingui basins, as well as the vegetation linked to the hydromorphic soil of the Oubangui basin composed of Uapaca spp., Guibourtia demeusii ,
Raphia vinifera , (Boulvert, 1986)
