Site description The site consists of a length of about 21 km of the Senegal river and its immediate riparian habitat. It lies upstream of Djoudj wetlands (site SN001) and north of both Ndiaël basin (SN002) and Lac de Guiers (SN003). The habitat consists of highly modified and cultivated areas of land, with extensive rice-fields and market gardens and associated irrigation and drainage canals and ditches, adjacent to areas of fairly dense human habitation. The site is very closely linked to Lac de Guiers, which receives water from the river through sluices and a canal located at Richard-Toll. Between this site and Lac de Guiers lie extensive sugar-cane plantations. The site lies in the Sahel zone and the original habitat would have been thorn-bush savanna, dominated by Acacia spp. and Balanites aegyptiaca, shrubs of Boscia senegalensis and Salvadora persica, and larger trees adjacent to the river itself, including Combretum aculeatum, Grewia bicolor, Bombax costatum and Borassus aethiopicum. There were once extensive forests of Acacia nilotica along the banks of the Senegal river that were regularly inundated by floods and formed important refuges for Palearctic migrants. These forests have largely disappeared as a result of drought and exploitation for fuelwood.
