IBA Monitoring

Most recent IBA monitoring assessment
Year of assessment Threat score (pressure) Condition score (state) Action score (response)
2012 medium favourable high
Was the whole site covered? Yes State assessed by Habitat
Accuracy of information good

Threats to the site (pressure)
Threat Level 1 Threat Level 2 Timing Scope Severity Result
Biological resource use hunting & collecting terrestrial animals - intentional use (species being assessed is the target) happening now small area/few individuals (<10%) no or imperceptible deterioration low
Climate change and severe weather drought happening now some of area/population (10-49%) slow but significant deterioration medium
Human intrusions and disturbance recreational activities happening now small area/few individuals (<10%) no or imperceptible deterioration low
Natural system modifications dams & water management/use - dams (size unknown) happening now majority/most of area/population (50-90%) no or imperceptible deterioration low
Pollution domestic & urban waste water - type unknown/unrecorded happening now some of area/population (10-49%) no or imperceptible deterioration low
Pollution industrial & military effluents - type unknown/unrecorded likely in short term (within 4 years) some of area/population (10-49%) slow but significant deterioration medium

Condition of habitat (state)
Habitat Habitat Detail Reference Area (ha) Actual Area (ha) % of habitat remaining % of carrying capacity (overall) Result
Artificial/Terrestrial 0 0 good (> 90%) good (> 90%) near favourable
Grassland Steppes & dry calcareous 0 0 good (> 90%) good (> 90%) near favourable
Wetlands (inland) 0 0 good (> 90%) good (> 90%) near favourable

Conservation actions taken at site (response)
Conservation Designation Management Planning Conservation 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
