Nisyros island and surrounding islets This is an IBA in Danger! 

IBA Justification

The site was identified as important in 2000 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species'):
Species Current IUCN Red List Category Season Year(s) Population estimate at site IBA criteria met
Chukar Alectoris chukar LC resident 1996 abundant B2
Bonelli's Eagle Aquila fasciata LC resident 1996 2 breeding pairs B2
Eleonora's Falcon Falco eleonorae LC breeding 1997 60 breeding pairs A4ii, B1iii, B2, C2
Rüppell's Warbler Curruca ruppeli LC breeding 1996 frequent B3
Cretzschmar's Bunting Emberiza caesia LC breeding 1996 common B3, C6

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2000).

IBA Conservation

IBA conservation assessment
Year of assessment (most recent) State (condition) Pressure (threat) Response (action)
2019 not assessed very high low
Was the whole site assessed? State assessed by Accuracy of information
no unset medium

Pressure (threats to the trigger species and/or their habitats)
Threat level 1 Threat level 2 Timing Scope Severity Result
Biological resource use hunting & collecting terrestrial animals - unintentional effects (species is not the target) happening now small area/few individuals (<10%) slow but significant deterioration low
Energy production and mining renewable energy likely in short term (within 4 years) whole area/population (>90%) very rapid to severe deterioration very high
Human intrusions and disturbance work and other activities likely in short term (within 4 years) majority/most of area/population (50-90%) moderate to rapid deterioration high
Invasive and other problematic species and genes invasive non-native/alien species/diseases - named species happening now small area/few individuals (<10%) no or imperceptible deterioration low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected-area designation Management planning Other conservation action Result
Whole area of site (>90%) covered by appropriate conservation designation No management plan exists but the management planning process has begun Very little or no conservation action taking place low
