Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2016) is shown below.
| IBA conservation assessment | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2016 | not assessed | high | low |
| Whole site assessed? | State assessed by | Accuracy of information | |
| yes | unset | good | |
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Agricultural expansion and intensification | happening now | most of population/area (50–90%) | moderate decline (10–30% over 3 generations) | high |
| Human intrusions and disturbance | happening now | some of population/area (10–49%) | no or slight decline (<1% over 3 generations) | low |
| Biological resource use | happening now | few individuals/small area (<10%) | slow decline (1–10% over 3 generations) | low |
| Response (conservation actions taken for the trigger species and/or their habitats) | |||
|---|---|---|---|
| Designation | Planning | Action | Result |
| Whole area (>90%) covered by appropriate conservation designation | No management plan exists, but the management planning process has begun | Very little or no conservation action taking place | low |
