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
Stock Dove Columba oenas LC breeding 1992 101-500 breeding pairs B3

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)
2010 favourable low low
Was the whole site assessed? State assessed by Accuracy of information
yes population good

State (condition of the trigger species' populations)
Scientific name Common name Reference population Actual population Units % of population remaining Result
Columba oenas Stock Dove 100 100 breeding pairs 100 favourable

Pressure (threats to the trigger species and/or their habitats)
Threat level 1 Threat level 2 Timing Scope Severity Result
Invasive and other problematic species and genes problematic native species/diseases - named species happening now majority/most of area/population (50-90%) no or imperceptible deterioration low
Pollution air-borne pollutants - type unknown/unrecorded 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
Most of site (50-90%) covered (including the most critical parts for important bird species) A management plan exists but it is out of date or not comprehensive Some limited conservation initiatives are in place low
