Site details
Site description: The Béli river lies in the extreme north of the country, just south of the international frontier with Mali. The IBA comprises the length of the Béli in Burkina Faso, less the 5 km before the Mali and Niger boundaries, and including a 5-km-wide zone on each bank, to the north and south. It flows through an area of flat scrub steppe, interspersed with ancient sand-dunes covered with short grasses, large eroded flats and shallow wadis. Draining out of Mali, the seasonal Béli river, over much of its 140-km-long passage through Burkina, is a shallow drainage forming clusters of small lakes that progressively dry up after the rains, and which are bordered in places by dense thickets of Balanites aegyptiaca. Within 70 km of crossing the border into Niger, it joins the Niger river. Thousands of birds and domestic livestock share ponds during the dry season, when nomads bring their flocks to benefit from the abundant aquatic vegetation exposed by the shrinking shorelines. The most important areas for waterbirds are thought to be the clusters of dry season shallow ponds located about the nomad camps of Tin Akoff, Fadar Fadar and In Tangoum. Also included are areas of semi-desert grasslands away from the river, particularly south-west of Fadar Fadar, extending south of Forage Christine, which are sufficiently far from the river that they suffer from less grazing pressure.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that was identified using previously established criteria and thresholds for the identification of Important Bird and Biodiversity Areas (IBAs) and for which available data indicate that it does not meet global KBA criteria and thresholds set out in the Global Standard.
Additional biodiversity: See Box and Table 2 for key species. According to local poachers, a few Struthio camelus can still be found in the area but this needs confirmation. Balearica pavonina is present. The rarely reported Mirafra cordofanica has recently been found to occur in the western part of this site. Non-bird biodiversity: Mammals of global conservation concern include Gazella rufifrons (VU). In addition, sightings of G. dama (EN), G. dorcas (VU) and Acinonyx jubatus (VU) were reported in the 1980s.

Threats
Summary of threats to biodiversity at KBA: The Béli river lies within the Réserve Partielle du Sahel. The drainage of the Béli is threatened by the movement of sand, exacerbated by erosion as a result of overgrazing—there have been recent increases in the numbers of nomads and accompanying livestock using the area. There has also been a rise in poaching. The site is part of the area covered by the PRONAGEN programme.
| Threat level 1 | Threat level 2 | Threat level 3 | Timing |
|---|---|---|---|
| Agriculture & aquaculture | Livestock farming & ranching | Nomadic grazing | Only in the future |
