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 |
|---|---|---|---|---|
| Meller's Duck Anas melleri | EN | resident (1999) | 45 individuals | 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 status | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2017 | very unfavourable | high | high |
| Whole site assessed? | State assessed by | Accuracy of information | |
| no | habitat | medium | |
| State (condition of the key species' habitats) | |||
|---|---|---|---|
| Habitat | Quantity (% remaining) | Quality (% carrying capacity) | Result |
| Wetlands (inland) | poor (40–69%) | moderate (70–90%) | very unfavourable |
| Pressure (threats to the key species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Energy production and mining | happening now | most of population/area (50–90%) | moderate deterioration (10–30% in 3 generations) | high |
| Pollution | happening now | most of population/area (50–90%) | slow deterioration (1–10% over 3 generations) | high |
| Natural system modifications | happening now | few individuals/small area (<10%) | slow deterioration (1–10% over 3 generations) | low |
| Response (conservation actions taken for the key species and/or their habitats) | |||
|---|---|---|---|
| Designation | Planning | Action | Result |
| Whole area of site (>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 |
