1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2016) may differ.
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2016. The most recent assessment (2018) is shown below.
| IBA conservation assessment | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2018 | not assessed | high | medium |
| Whole site assessed? | State assessed by | Accuracy of information | |
| no | unset | medium | |
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Human intrusions and disturbance | happening now | majority/most of area/population (50-90%) | slow but significant deterioration | high |
