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
European Storm-petrel Hydrobates pelagicus	LC	resident	2008-2009	100-200 breeding pairs	B3, C6

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' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Marine Coastal/Supratidal	good (> 90%)	good (> 90%)	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Human intrusions and disturbance	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
Most of site (50-90%) covered (including the most critical parts for important bird species)	No management plan exists but the management planning process has begun	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	low

Year	Protected Area	Designation	% overlap with IBA
1997	Dunas de Liencres y Estuario del Pas	Site of Community Importance (Habitats Directive)	<1
2006	LIC-DUNAS DE LIENCRES Y ESTUARIO DEL PAS	Zona de la Red Ecológica Europea Natura 2000	2
