Data Zone
The site was identified as important in 2009 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 | 2000-2007 | 1-5 males | C6 |
| Spotted Crake Porzana porzana | LC | passage | 2000-2009 | 3-5 individuals | C6 |
| White Stork Ciconia ciconia | LC | non-breeding | 2005-2009 | 1-15 individuals | C6 |
| Aquatic Warbler Acrocephalus paludicola | VU | passage | 2005 | 2 individuals | C6 |
1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2009) may differ.
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2013) is shown below.
| IBA conservation assessment | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2013 | not assessed | high | high |
| Whole site assessed? | State assessed by | Accuracy of information | |
| yes | unset | unknown | |
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Agricultural expansion and intensification | happening now | majority/most of area/population (50-90%) | slow but significant deterioration | high |
| Transportation and service corridors | likely in short term (within 4 years) | small area/few individuals (<10%) | moderate to rapid deterioration | low |
| Human intrusions and disturbance | happening now | small area/few individuals (<10%) | no or imperceptible deterioration | low |
| Residential and commercial development | 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 |
| Whole area of site (>90%) covered by appropriate conservation designation | A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species | Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity | high |
