1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2008) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2008. The most recent assessment (2019) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high

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	No management planning has taken place	Very little or no conservation action taking place	low

Year	Protected Area	Designation	% overlap with IBA
2008	Aydar-Arnasay Lakes system	Ramsar Site, Wetland of International Importance	100

Habitat1	Habitat detail	% of IBA
Wetlands (inland)	Standing fresh water, Water-fringe vegetation	62
Desert	Desert & semi-desert - sandy	31
Forest	Wooded desert & semi-desert	7

1. IUCN Habitat classification.
