ES062
Topas


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
Great Bustard Otis tarda EN resident (2009) 100–120 birds A1, C1

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 poor very high very low
Whole site assessed? State assessed by Accuracy of information
yes habitat poor

State (condition of the trigger species' populations)
Species Actual vs Reference (units) % remaining Result
Great Bustard Otis tarda 20 / 70 (birds) 29 not assessed

State (condition of the trigger species' habitats)
Habitat Quantity (% remaining) Quality (% carrying capacity) Result
Artificial/Terrestrial moderate (70–90%) moderate (70–90%) poor

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Invasive and other problematic species and genes happe­ning now most of popul­ation/area (50–90%) rapid decline (>30% over 3 gener­ations) very high
Transportation and service corridors happe­ning now some of popul­ation/area (10–49%) rapid decline (>30% over 3 gener­ations) high
Biological resource use happe­ning now some of popul­ation/area (10–49%) rapid decline (>30% over 3 gener­ations) high
Pollution happe­ning now some of popul­ation/area (10–49%) moderate decline (10–30% over 3 gener­ations) high
Human intrusions and disturbance happe­ning now some of popul­ation/area (10–49%) slow decline (1–10% over 3 gener­ations) medium
Agricultural expansion and intensification happe­ning now few indivi­duals/small area (<10%) slow decline (1–10% over 3 gener­ations) low
Residential and commercial development happe­ning now few indivi­duals/small area (<10%) no or slight decline (<1% over 3 gener­ations) low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation Planning Action Result
Little/none of area covered (<10%) No management planning has taken place Very little or no conservation action taking place very low
