The site was identified as internationally important for bird conservation in 1999 because it was regularly supporting significant populations of the species listed below, meeting IBA criteria.

Populations meeting IBA criteria ('key species') at the site:

Species	Red List	Season (year/s of estimate)	Size	IBA criteria
Madagascar Fish-eagle Haliaeetus vociferoides	CR	resident (1997)	3 breeding pairs	A1, A3

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1999. The most recent assessment (2017) is shown below.

Pressure (threats to the key species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	happen­ing now	most of popul­ation/area (50–90%)	moderate deteri­oration (10–30% in 3 gener­ations)	high
Energy production and mining	happen­ing now	most of popul­ation/area (50–90%)	slow deteri­oration (1–10% over 3 gener­ations)	high
Human intrusions and disturbance	happen­ing now	most of popul­ation/area (50–90%)	slow deteri­oration (1–10% over 3 gener­ations)	high

Response (conservation actions taken for the key species and/or their habitats)
Designation	Planning	Action	Result
Unknown	A compre­hensive and appropriate manage­ment plan exists that aims to maintain or improve the popul­ations of qualify­ing bird species	Unknown	low

Year	Protected Area	Designation (management category)	% coverage of IBA
