ES018
Ribadesella-Tina Mayor


IBA Justification

The site was identified as internationally important for bird conservation 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 List Season (year/s of estimate) Size IBA criteria
European Storm-petrel Hydrobates pelagicus LC resident (1995) min 700 pairs B3, C6

IBA Conservation

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.

IBA conservation assessment
Year of assessment State Pressure Response
2008 moderate very high low
Whole site assessed? State assessed by Accuracy of information
yes population good

State (condition of the trigger species' populations)
Species Actual vs Reference (units) % remaining Result
European Storm-petrel Hydrobates pelagicus 600 / 700 (pairs) 86 moderate

State (condition of the trigger species' habitats)
Habitat Quantity (% remaining) Quality (% carrying capacity) Result
Forest moderate (70–90%) poor (40–69%) very poor
Marine Coastal/Supratidal moderate (70–90%) good (>90%) moderate

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Residential and commercial development happe­ning now most of popul­ation/area (50–90%) rapid decline (>30% over 3 gener­ations) very high
Transportation and service corridors happe­ning now whole of popul­ation/area (>90%) slow decline (1–10% over 3 gener­ations) high
Human intrusions and disturbance happe­ning now whole of popul­ation/area (>90%) slow decline (1–10% over 3 gener­ations) high
Agricultural expansion and intensification happe­ning now most of popul­ation/area (50–90%) slow decline (1–10% over 3 gener­ations) high
Pollution happe­ning now some of popul­ation/area (10–49%) moderate decline (10–30% over 3 gener­ations) high
Natural system modifications happe­ning now some of popul­ation/area (10–49%) moderate decline (10–30% over 3 gener­ations) high
Biological resource use happe­ning now some of popul­ation/area (10–49%) slow decline (1–10% over 3 gener­ations) medium

Response (conservation actions taken for the trigger species and/or their habitats)
Designation Planning Action Result
Some of area covered (10–49%) Not assessed Substantive conservation measures are being implemented, but these are not compre­hensive and are limited by resources and capacity low
