Data Zone
The site was identified as internationally important for bird conservation in 2021 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 |
|---|---|---|---|---|
| Whimbrel Numenius phaeopus | LC | non-breeding (2016–2021) | 400–500 birds | B3a |
| Hudsonian Godwit Limosa haemastica | VU | non-breeding (2016–2021) | 930–1,000 birds | A4, B3a |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2021. The most recent assessment (2015) is shown below.
| IBA conservation assessment | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2015 | moderate | medium | low |
| Whole site assessed? | State assessed by | Accuracy of information | |
| yes | habitat | medium | |
| State (condition of the trigger species' habitats) | |||
|---|---|---|---|
| Habitat | Quantity (% remaining) | Quality (% carrying capacity) | Result |
| Forest | - | moderate (70–90%) | moderate |
| Marine Neritic | - | good (>90%) | good |
| Marine Coastal/Supratidal | - | good (>90%) | good |
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Pollution | happening now | some of population/area (10–49%) | slow decline (1–10% over 3 generations) | medium |
| Agricultural expansion and intensification | happening now | few individuals/small area (<10%) | no or slight decline (<1% over 3 generations) | low |
| Response (conservation actions taken for the trigger species and/or their habitats) | |||
|---|---|---|---|
| Designation | Planning | Action | Result |
| Little/none of area covered (<10%) | No management plan exists, but the management planning process has begun | Some limited conservation initiatives are in place | low |
| Habitat | % of IBA | Habitat detail |
