The site was identified as important in 2008 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species') at the site:

Species	Red List1	Season	Year(s)	Size	IBA criteria
Caucasian Grouse Lyrurus mlokosiewiczi	NT	resident	1987	50 individuals	A2, A3
Caucasian Grouse Lyrurus mlokosiewiczi	NT	resident	2007	20-30 males	A1, A2, A3
Corncrake Crex crex	LC	breeding	2007	20-30 males	A1
Yellow-billed Chough Pyrrhocorax graculus	LC	resident	2007	30-50 breeding pairs	A3
Krueper's Nuthatch Sitta krueperi	LC	breeding	2007	50-100 breeding pairs	A1
Wallcreeper Tichodroma muraria	LC	breeding	2007	2-3 breeding pairs	A3
Semi-collared Flycatcher Ficedula semitorquata	LC	breeding	2007	200-300 breeding pairs	A1
Alpine Accentor Prunella collaris	LC	breeding	2007	10-30 breeding pairs	A3

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 (2007) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Bearded Vulture Gypaetus barbatus	1	1	breeding pairs	100	not assessed
Egyptian Vulture Neophron percnopterus	1	0	breeding pairs	0	not assessed
Griffon Vulture Gyps fulvus	5	2	individuals	40	not assessed

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Biological resource use	happening now	small area/few individuals (<10%)	very rapid to severe deterioration	low
Agricultural expansion and intensification	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
Some of site covered (10-49%)	No management planning has taken place	Very little or no conservation action taking place	negligible
