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 (2010) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	good (> 90%)	good (> 90%)	favourable
Grassland	good (> 90%)	good (> 90%)	favourable
Wetlands (inland)	good (> 90%)	good (> 90%)	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Climate change and severe weather	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Natural system modifications	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Not assessed	Not assessed	Not assessed	not assessed

Year	Protected Area	Designation	% overlap with IBA
1934	Naurzumskiy	State Nature Reserve	100
2008	Saryarka – Steppe and Lakes of Northern Kazakhstan	World Heritage Site (natural or mixed)	100
2009	Naurzum Lake System	Ramsar Site, Wetland of International Importance	100
