Data Zone
The site was identified as internationally important for bird conservation 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 List | Season (year/s of estimate) | Size | IBA criteria |
|---|---|---|---|---|
| Red-crested Pochard Netta rufina | LC | winter (1998) | 870–2,200 birds | A4i, B1i |
| Tufted Duck Aythya fuligula | LC | winter (1998) | 4,600–9,600 birds | B1i |
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.
| IBA conservation assessment | |||

|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Human intrusions and disturbance | happening now | most of population/area (50–90%) | no or slight decline (<1% over 3 generations) | low |
| Energy production and mining | happening now | some of population/area (10–49%) | no or slight decline (<1% over 3 generations) | low |
| Invasive and other problematic species and genes | likely in short term (<4 years) | most of population/area (50–90%) | no or slight decline (<1% over 3 generations) | low |
| Pollution | likely in long term (>4 years) | whole of population/area (>90%) | no or slight decline (<1% over 3 generations) | low |
