Sobrón canyon


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
Griffon Vulture Gyps fulvus LC resident (2008) 222–255 pairs B1iii, C2, 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 (2007) is shown below.

Year of assessment State Pressure Response
2007 good high low
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
Griffon Vulture Gyps fulvus 254 / 119 (pairs) 100 good

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Residential and commercial development happe­ning now some of popul­ation/area (10–49%) moderate decline (10–30% over 3 gener­ations) high
Transportation and service corridors happe­ning now some of popul­ation/area (10–49%) slow decline (1–10% over 3 gener­ations) medium
Human intrusions and disturbance happe­ning now some of popul­ation/area (10–49%) slow decline (1–10% over 3 gener­ations) medium
Natural system modifications happe­ning now some of popul­ation/area (10–49%) slow decline (1–10% over 3 gener­ations) medium
Invasive and other problematic species and genes likely in short term (<4 years) some of popul­ation/area (10–49%) moderate decline (10–30% over 3 gener­ations) medium
Pollution likely in short term (<4 years) 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Some of area covered (10–49%) A management plan exists, but it is out of date or not compre­hensive Substantive conservation measures are being implemented, but these are not compre­hensive and are limited by resources and capacity low
