The site was identified as internationally important for bird conservation in 2001 because it was regularly supporting significant populations of the species listed below, meeting IBA criteria.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2001. The most recent assessment (2009) is shown below.

State (condition of the key species' populations)
Species	Actual vs Reference (units)	% remaining	Result
Rüppell's Vulture Gyps rueppelli	109 / 110 (breeding pairs)	100	favourable

State (condition of the key species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	good (>90%)	moderate (70–90%)	near favourable

Pressure (threats to the key species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happen­ing now	most of popul­ation/area (50–90%)	moderate deteri­oration (10–30% in 3 gener­ations)	high

Response (conservation actions taken for the key species and/or their habitats)
Designation	Planning	Action	Result
Whole area of site (>90%) covered by appropriate conservation designation	No manage­ment plan exists, but the manage­ment planning process has begun	Substantive conservation measures are being implemented, but these are not comprehensive and are limited by resources and capacity	medium

Year	Protected Area	Designation (management category)	% coverage of IBA
1954	W du Burkina Faso	National Park (II)	25
1954	Arly	Faunal Reserve (IV)	8
1955	Singou	Faunal Reserve (IV)	21
