Site description Binder–Léré Faunal Reserve is situated in south-west Chad, on the border with Cameroon. The area is essentially rocky with eroded soils. The reserve lies in the transition zone between open forest and savanna woodland and is dominated by leguminous tree species in the south and by Combretum woodland in the north. The savanna is characterized by shrubs of the genera Anogeissus and Boswellia. The Mayo-Kébbi river flows from east to west through the reserve. Included in the reserve are both the Gauthiot Falls and, towards its western end, Lakes Léré and Tréné, through which the Mayo-Kébbi flows, before continuing westwards into Cameroon and Nigeria to join the Niger river system. Lake Léré is 14.5 km long by 4 km wide while Tréné is 6 km long and 2 km wide. Near the headwaters of the Mayo-Kébbi, just outside the reserve, there is a vast plain containing the Touboiris and Loké marshes. Mean annual rainfall is between 800–950 mm.

Key Biodiversity See Box and Table 2 for key species. In addition, Falco naumanni has been recorded (status is unknown), as have two species restricted to the Sahel biome (see Table 2). Although no counts have been made, it is believed that Lakes Léré and Tréné are important for migrant Palearctic waterbirds.

Non-bird biodiversity: Threatened mammal species include Trichechus senegalensis (VU).
