ES351
Coast between Arinaga and Castillo del Romeral


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
Sandwich Tern Thalasseus sandvicensis LC winter (1994) 39 birds 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 good very high medium
Whole site assessed? State assessed by Accuracy of information
yes population medium

State (condition of the trigger species' populations)
Species Actual vs Reference (units) % remaining Result
Charadrius alexandrinus 2 / 2 (pairs) 100 good

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Human intrusions and disturbance happe­ning now whole of popul­ation/area (>90%) rapid decline (>30% over 3 gener­ations) very high
Climate change and severe weather happe­ning now whole of popul­ation/area (>90%) moderate decline (10–30% over 3 gener­ations) very high
Transportation and service corridors happe­ning now most of popul­ation/area (50–90%) rapid decline (>30% over 3 gener­ations) very high
Invasive and other problematic species and genes happe­ning now most of popul­ation/area (50–90%) rapid decline (>30% over 3 gener­ations) very high
Pollution happe­ning now most of popul­ation/area (50–90%) rapid decline (>30% over 3 gener­ations) very high
Biological resource use happe­ning now most of popul­ation/area (50–90%) moderate decline (10–30% over 3 gener­ations) high
Residential and commercial development happe­ning now some of popul­ation/area (10–49%) rapid decline (>30% over 3 gener­ations) high
Agricultural expansion and intensification happe­ning now some of popul­ation/area (10–49%) moderate decline (10–30% over 3 gener­ations) high
Energy production and mining 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

Response (conservation actions taken for the trigger species and/or their habitats)
Designation Planning Action Result
Some of area covered (10–49%) A compre­hensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species Substantive conservation measures are being implemented, but these are not compre­hensive and are limited by resources and capacity medium
