IBA Justification

The site was identified as important in 2010 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 List1 Season Year(s) Size IBA criteria
Corncrake Crex crex LC breeding 2001-2008 56-64 males C1

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2010) may differ.


IBA Conservation

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2010) is shown below.

IBA conservation assessment
Year of assessment State Pressure Response
2010 very unfavourable high low
Whole site assessed? State assessed by Accuracy of information
yes habitat medium

State (condition of the trigger species' habitats)
Habitat Quantity (% remaining) Quality (% carrying capacity) Result
Grassland poor (40-69%) poor (40-69%) very unfavourable
Forest moderate (70-90%) moderate (70-90%) unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Agricultural expansion and intensification happening now some of area/population (10-49%) moderate to rapid deterioration high
Climate change and severe weather happening now majority/most of area/population (50-90%) moderate to rapid deterioration high
Natural system modifications happening now small area/few individuals (<10%) moderate to rapid deterioration low
Residential and commercial development happening now small area/few individuals (<10%) slow but significant deterioration low
Pollution happening now small area/few individuals (<10%) no or imperceptible deterioration low
Transportation and service corridors happening now some of area/population (10-49%) no or imperceptible deterioration low
Human intrusions and disturbance 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 areas Management plan Other 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site (50-90%) covered (including the most critical parts for important bird species) A management plan exists but it is out of date or not comprehensive Very little or no conservation action taking place low
