1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2007) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2016) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Human intrusions and disturbance	happening now	some of area/population (10-49%)	no or imperceptible deterioration	low
Biological resource use	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	No management plan exists but the management planning process has begun	Very little or no conservation action taking place	low

Year	Protected Area	Designation	% overlap with IBA
1990	Ugam-Chatkal	National Park	100

Habitat1	Habitat detail	% of IBA
Grassland	Alpine, subalpine & boreal, Mesophile grassland & tall grass steppe	53
Other		27
Rocky areas (eg. inland cliffs, mountain peaks)	Scree, boulders & bare rocky areas, Inland cliffs	16
Forest	Flood-plain, Native coniferous	2
Wetlands (inland)	Fens, transition mires & springs, Standing fresh water, Rivers & streams, Water-fringe vegetation	1
