Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1999. The most recent assessment (2019) is shown below.
| IBA conservation assessment | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2019 | good | very high | high |
| Whole site assessed? | State assessed by | Accuracy of information | |
| yes | habitat | good | |
| State (condition of the trigger species' habitats) | |||
|---|---|---|---|
| Habitat | Quantity (% remaining) | Quality (% carrying capacity) | Result |
| Forest | good (>90%) | good (>90%) | good |
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Biological resource use | happening now | most of population/area (50–90%) | rapid decline (>30% over 3 generations) | very high |
| Climate change and severe weather | happening now | most of population/area (50–90%) | rapid decline (>30% over 3 generations) | very high |

|---|---|---|---|
| Designation | Planning | Action | Result |
| Whole area (>90%) covered by appropriate conservation designation | A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species | Substantive conservation measures are being implemented, but these are not comprehensive and are limited by resources and capacity | high |
