Gaulosen


IBA Justification

The site was identified as important in 2014 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
Greylag Goose Anser anser LC passage 2007-2013 1,460-6,200 individuals B1i
Pink-footed Goose Anser brachyrhynchus LC passage 2010-2013 620-2,500 individuals B1i
Velvet Scoter Melanitta fusca VU passage 2005-2014 50-130 individuals A1

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2014).

Pressure (threats to the trigger species and/or their habitats)
Threat level 1 Threat level 2 Timing Scope Severity Result
Agricultural expansion and intensification annual & perennial non-timber crops - shifting agriculture happening now small area/few individuals (<10%) no or imperceptible deterioration low
Agricultural expansion and intensification livestock farming and ranching (includes forest grazing) - agro-industry grazing, ranching or farmin happening now some of area/population (10-49%) no or imperceptible deterioration low
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 habitat shifting and alteration happening now small area/few individuals (<10%) no or imperceptible deterioration low
Climate change and severe weather storms and floods 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) Unknown The conservation measures needed for the site are being comprehensively and effectively implemented low
