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 |
|---|---|---|---|---|
| Meller's Duck Anas melleri | EN | resident (1999) | 45 birds | A1, A2, A3, A4i |
| Madagascar Grebe Tachybaptus pelzelnii | EN | resident (1999) | present | A1 |
| Madagascar Rail Rallus madagascariensis | VU | resident (1999) | present | A2, A3 |
| Madagascar Snipe Gallinago macrodactyla | VU | resident (1999) | common | A2, 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 (2017) is shown below.
| IBA conservation assessment | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2017 | very poor | high | high |
| Whole site assessed? | State assessed by | Accuracy of information | |
| no | habitat | medium | |
| State (condition of the trigger species' habitats) | |||
|---|---|---|---|
| Habitat | Quantity (% remaining) | Quality (% carrying capacity) | Result |
| Wetlands (inland) | poor (40–69%) | moderate (70–90%) | very poor |
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Energy production and mining | happening now | most of population/area (50–90%) | moderate decline (10–30% over 3 generations) | high |
| Pollution | happening now | most of population/area (50–90%) | slow decline (1–10% over 3 generations) | high |
| Natural system modifications | 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 | A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species | The conservation measures needed for the site are being comprehensively and effectively implemented | high |
