Data Zone
The site was identified as important in 1999 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.
Populations meeting IBA criteria ('trigger species'):| Species | Current IUCN Red List Category | Season | Year(s) | Population estimate at site | IBA criteria met |
|---|---|---|---|---|---|
| Grey-crested Helmetshrike Prionops poliolophus | NT | resident | 1999 | present | A1, A2 |
| Red-throated Tit Melaniparus fringillinus | LC | resident | 1999 | present | A1 |
| Hunter's Cisticola Cisticola hunteri | LC | resident | 1999 | present | A2 |
| Jackson's Widowbird Euplectes jacksoni | NT | resident | 1999 | present | A1, A2 |
The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (1999).
