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'):Species | Current IUCN Red List Category | Season | Year(s) | Population estimate at site | IBA criteria met |
---|---|---|---|---|---|
Ferruginous Duck Aythya nyroca | NT | breeding | 2008-2009 | 1-2 breeding pairs | C7 |
The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2010).

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 |
Biological resource use | hunting & collecting terrestrial animals - persecution/control | happening now | some of area/population (10-49%) | no or imperceptible deterioration | low |
Human intrusions and disturbance | recreational activities | happening now | some of area/population (10-49%) | no or imperceptible deterioration | low |
Natural system modifications | fire & fire suppression - increase in fire frequency/intensity | past (and unlikely to return) and no longer limiting | some of area/population (10-49%) | slow but significant deterioration | low |
