The site was identified as important in 2000 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 |
---|---|---|---|---|---|
Red-crested Pochard Netta rufina | LC | winter | 1998 | 870-2,200 individuals | A4i, B1i |
Tufted Duck Aythya fuligula | LC | winter | 1998 | 4,600-9,600 individuals | B1i |
1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2000) may differ.
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2013) is shown below.

Threat | Timing | Scope | Severity | Result |
Energy production and mining | happening now | some of area/population (10-49%) | no or imperceptible deterioration | low |
Human intrusions and disturbance | happening now | majority/most of area/population (50-90%) | no or imperceptible deterioration | low |
Pollution | likely in long term (beyond 4 years) | whole area/population (>90%) | no or imperceptible deterioration | low |
Invasive and other problematic species and genes | likely in short term (within 4 years) | majority/most of area/population (50-90%) | no or imperceptible deterioration | low |
