The site was identified as important in 1999 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

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

Species	Red List1	Season	Year(s)	Size	IBA criteria
Meller's Duck Anas melleri	EN	resident	1999	45 individuals	A1, A2, A3, A4i
Madagascar Grebe Tachybaptus pelzelnii	EN	resident	1999	present	A1
Madagascar Rail Rallus madagascariensis	VU	resident	1999	present	A2, A3
Madagascar Snipe Gallinago macrodactyla	VU	resident	1999	common	A2, A3

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (1999) may differ.

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.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Wetlands (inland)	poor (40-69%)	moderate (70-90%)	very unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Energy production and mining	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Pollution	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Natural system modifications	happening now	small area/few individuals (<10%)	slow but significant deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Whole area of site (>90%) covered by appropriate conservation designation	A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	The conservation measures needed for the site are being comprehensively and effectively implemented	high
