The majority area belongs to the Sahelian zone known but is a particular ecological unit as a wetland. It covers an area ranging from 30,000 to 35.000Km2 and includes the floodplains of the Niger and Bani, the continental rise of the South -West north - east of the lake area from Delta beyond Erg Bara as well as parts of Ségou, Mopti and Timbuktu (lakeside area) .C 'is the area filled most birds, composed in particular from 11 to 19 migratory bird species.
