The site was identified as important in 2011 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
Grey Partridge Perdix perdix	LC	resident	2004	min 346 breeding pairs	C6
Western Capercaillie Tetrao urogallus	LC	resident	2009	3-4 males	C6
European Honey-buzzard Pernis apivorus	LC	breeding	2004	max 15 breeding pairs	C6
Egyptian Vulture Neophron percnopterus	EN	breeding	2008	min 23 breeding pairs	A1, B2, C1, C2
Black Woodpecker Dryocopus martius	LC	resident	2010	min 15 breeding pairs	C6
Middle Spotted Woodpecker Leiopicus medius	LC	resident	2004	181-255 breeding pairs	C6
Red-billed Chough Pyrrhocorax pyrrhocorax	LC	non-breeding	2011	min 700 individuals	C2
Red-billed Chough Pyrrhocorax pyrrhocorax	LC	resident	2011	min 250 breeding pairs	B2, C2
Rufous-tailed Rock-thrush Monticola saxatilis	LC	breeding	2011	min 80 breeding pairs	B2

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2011) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2011. The most recent assessment (2008) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Western Capercaillie Tetrao urogallus	153	9	males	6	very unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Transportation and service corridors	likely in short term (within 4 years)	some of area/population (10-49%)	very rapid to severe deterioration	high
Agricultural expansion and intensification	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Residential and commercial development	likely in long term (beyond 4 years)	some of area/population (10-49%)	moderate to rapid deterioration	medium
Pollution	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Human intrusions and disturbance	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Natural system modifications	past (and unlikely to return) and no longer limiting	small area/few individuals (<10%)	slow but significant deterioration	low
Energy production and mining	likely in short term (within 4 years)	small area/few individuals (<10%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Little/none of site covered (<10%)	No management planning has taken place	Some limited conservation initiatives are in place	negligible
