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) | 500–749 birds | B3a |
| Hudsonian Godwit Limosa haemastica | VU | non-breeding (2016–2021) | 1,000–1,809 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.

| Grassland | - | moderate (70–90%) | poor |

| Threat | Timing | Scope | Severity | Result |
| Agricultural expansion and intensification | happening now | some of population/area (10–49%) | moderate decline (10–30% over 3 generations) | high |
| Invasive and other problematic species and genes | happening now | some of population/area (10–49%) | moderate decline (10–30% over 3 generations) | high |
| Residential and commercial development | happening now | some of population/area (10–49%) | moderate decline (10–30% over 3 generations) | high |
| Response (conservation actions taken for the trigger species and/or their habitats) | |||
