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%)	good (> 90%)	near favourable
Grassland	moderate (70-90%)	good (> 90%)	near favourable
Wetlands (inland)	moderate (70-90%)	good (> 90%)	near favourable

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%)	slow but significant deterioration	medium
Biological resource use	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Natural system modifications	happening now	small area/few individuals (<10%)	moderate to rapid deterioration	low

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
1991	Ranomafana	National Park	70
2007	Rainforests of the Atsinanana	World Heritage Site (natural or mixed)	73
