Data Zone
The site was identified as internationally important for bird conservation in 2019 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 |
|---|---|---|---|---|
| Chilean Flamingo Phoenicopterus chilensis | NT | non-breeding (2015–2019) | 5–200 birds | B1a |
| Grey Gull Larus modestus | LC | non-breeding (2015–2019) | 8–500 birds | A4, B3a |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2019. The most recent assessment (2019) is shown below.
| IBA conservation assessment | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2019 | poor | very high | low |
| Whole site assessed? | State assessed by | Accuracy of information | |
| no | habitat | good | |
| State (condition of the trigger species' habitats) | |||
|---|---|---|---|
| Habitat | Quantity (% remaining) | Quality (% carrying capacity) | Result |
| Marine Intertidal | moderate (70–90%) | moderate (70–90%) | poor |
| Marine Neritic | good (>90%) | moderate (70–90%) | moderate |
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Pollution | happening now | whole of population/area (>90%) | moderate decline (10–30% over 3 generations) | very high |
| Human intrusions and disturbance | happening now | whole of population/area (>90%) | slow decline (1–10% over 3 generations) | high |
| Response (conservation actions taken for the trigger species and/or their habitats) | |||
|---|---|---|---|
| Designation | Planning | Action | Result |
| Unknown | No management planning has taken place | Substantive conservation measures are being implemented, but these are not comprehensive and are limited by resources and capacity | low |
| Habitat | % of IBA | Habitat detail |
|---|---|---|
| Marine Intertidal | major (>10) | |
| Marine Neritic | minor (<10) |
| Land use | % of IBA |
|---|---|
| fisheries/aquaculture | minor (<10) |
| tourism/recreation | minor (<10) |
