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 IBA criteria.
Populations meeting IBA criteria ('key species') at the site:| Species | Red List | Season (year/s of estimate) | Size | IBA criteria |
|---|---|---|---|---|
| Papyrus Gonolek Laniarius mufumbiri | NT | resident (1999) | present | A1, A3 |
| Carruthers's Cisticola Cisticola carruthersi | LC | resident (1999) | present | A3 |
| White-winged Swamp-warbler Bradypterus carpalis | LC | resident (1999) | present | A3 |
| Black-lored Babbler Turdoides sharpei | LC | resident (1999) | present | A3 |
| Red-chested Sunbird Cinnyris erythrocercus | LC | resident (1999) | present | A3 |
| Northern Brown-throated Weaver Ploceus castanops | LC | resident (1999) | present | A3 |
| Papyrus Canary Crithagra koliensis | LC | resident (1999) | present | A3 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1999. The most recent assessment (2022) is shown below.
| IBA conservation status | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2022 | very unfavourable | very high | low |
| Whole site assessed? | State assessed by | Accuracy of information | |
| no | habitat | good | |
| State (condition of the key species' habitats) | |||
|---|---|---|---|
| Habitat | Quantity (% remaining) | Quality (% carrying capacity) | Result |
| Wetlands (inland) | very poor (<40%) | very poor (<40%) | very unfavourable |
| Pressure (threats to the key species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Agricultural expansion and intensification | happening now | whole population/area (>90%) | rapid deterioration (>30% over 3 generations) | very high |
| Energy production and mining | happening now | most of population/area (50–90%) | moderate deterioration (10–30% in 3 generations) | high |
| Biological resource use | happening now | most of population/area (50–90%) | moderate deterioration (10–30% in 3 generations) | high |
| Transportation and service corridors | happening now | some of population/area (10–49%) | slow deterioration (1–10% over 3 generations) | medium |
| Human intrusions and disturbance | happening now | some of population/area (10–49%) | slow deterioration (1–10% over 3 generations) | medium |
| Pollution | happening now | some of population/area (10–49%) | slow deterioration (1–10% over 3 generations) | medium |
| Climate change and severe weather | likely in short term (within 4 years) | most of population/area (50–90%) | slow deterioration (1–10% over 3 generations) | medium |
| Response (conservation actions taken for the key species and/or their habitats) | |||
