Data Zone
The site was identified as internationally important for bird conservation in 1999 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 |
|---|---|---|---|---|
| Fischer's Turaco Tauraco fischeri | NT | resident (1999) | present | A1 |
| Southern Banded Snake-eagle Circaetus fasciolatus | NT | resident (1999) | present | A1 |
| Spotted Ground-thrush Geokichla guttata | VU | non-breeding (1999) | present | A1 |
| Plain-backed Sunbird Anthreptes reichenowi | NT | resident (1999) | present | A1 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1999. The most recent assessment (2021) is shown below.
