Populations meeting IBA criteria ('trigger species'):
Species Current IUCN Red List Category Season Year(s) Population estimate at site IBA criteria met
Whooper Swan Cygnus cygnus LC passage 1996 101-500 individuals B1i, C2
Spotted Crake Porzana porzana LC breeding 1996 45-70 breeding pairs B3, C6
Common Crane Grus grus LC passage 1996 101-500 individuals B1i, C2
Eurasian Bittern Botaurus stellaris LC breeding 1996 10-11 breeding pairs B2, C6

Pressure (threats to the trigger species and/or their habitats)
Threat level 1 Threat level 2 Timing Scope Severity Result
Natural system modifications dams & water management/use - dams (size unknown) happening now some of area/population (10-49%) slow but significant deterioration medium
Pollution agricultural & forestry effluents - type unknown/unrecorded happening now majority/most of area/population (50-90%) slow but significant deterioration high

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 A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species The conservation measures needed for the site are being comprehensively and effectively implemented high
