Data Zone
The site was identified as internationally important for bird conservation in 1998 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 |
|---|---|---|---|---|
| Grey Cuckooshrike Ceblepyris caesius | LC | resident (1998) | present | A3 |
| Olive Bushshrike Chlorophoneus olivaceus | LC | resident (1998) | present | A3 |
| Bush Blackcap Sylvia nigricapillus | VU | resident (1998) | present | A2, A3 |
| Spotted Ground-thrush Geokichla guttata | VU | breeding (-) | present | A1 |
| Brown Scrub-robin Tychaedon signata | LC | resident (1998) | present | A2 |
| White-starred Robin Pogonocichla stellata | LC | resident (1998) | present | A3 |
| Chorister Robin-chat Cossypha dichroa | LC | resident (1998) | present | A2, A3 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1998. The most recent assessment (2014) is shown below.
