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
Forest	-	moderate (70-90%)	unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Energy production and mining	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Natural system modifications	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Biological resource use	happening now	some of area/population (10-49%)	slow but significant deterioration	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other 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	% overlap with IBA
1927	Zahamena	National Park	65
2007	Rainforests of the Atsinanana	World Heritage Site (natural or mixed)	100
