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
Cinereous Vulture Aegypius monachus	NT	resident	2004	min 114 breeding pairs	A1, A4ii, B1iii, B2, C1, C2, C6
Spanish Imperial Eagle Aquila adalberti	VU	resident	2004	min 2 breeding pairs	A1, B2, C1, C2

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 (2007) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Cinereous Vulture Aegypius monachus	90	90	breeding pairs	100	favourable

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

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	likely in short term (within 4 years)	whole area/population (>90%)	very rapid to severe deterioration	very high
Human intrusions and disturbance	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high
Pollution	happening now	some of area/population (10-49%)	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
Invasive and other problematic species and genes	happening now	some of area/population (10-49%)	slow but significant deterioration	medium

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	A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	The conservation measures needed for the site are being comprehensively and effectively implemented	high
