- Association Densities of Cola laurifolia and Isoberlinia doka increased from upstream to downstream.
- Association Recoveries of Andropogon gayanus, Cassia mimosoïdes and Panicum maximum increased from upstream to downstream.
- Association Recoveries of Andropogon tectorum, Hyptechis suaveolens and Aptechis suaveolens increased from upstream to downstream.
- Association Density of Berlinia grandiflora, Isoberlinia doka and Combretum glutinosum was particularly linked to physicochemical parameters of water.
- Association Recovery of Andropogon gayanus, Cassia mimosoïdes and Detarium microcarpa was particularly linked to physicochemical parameters of water.
- Association Recovery of Gynandropsis gynandra was particularly linked to physicochemical parameters of water.
- Observation The relationship between the two groups of parameters had a first canonical coefficient of 0.75.
- Observation Species richness of shrubs and herbaceous plants contributed to the relationship between vegetation and water parameters.
- Observation Water temperature and Biochemical Oxygen Demand for 5 days contributed to the relationship, with dissolved oxygen contributing to a lesser extent.
- Association Human activities from upstream to downstream had a detrimental effect on the composition of riparian flora.
- Association Human activities from upstream to downstream had a detrimental effect on water quality.
- Observation The water is of average quality according to the parameters measured.
