Data Zone
The site was identified as internationally important for bird conservation in 2020 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 |
|---|---|---|---|---|
| Ruddy-headed Goose Chloephaga rubidiceps | LC | breeding (2018–2019) | 128 birds | B3a |
| Ruddy-headed Goose Chloephaga rubidiceps | LC | breeding (2016–2020) | 1–165 birds | B3a |
| Crested Duck Lophonetta specularioides | LC | breeding (2016–2020) | 246–300 birds | B3a |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2020. The most recent assessment (2015) is shown below.
| IBA conservation assessment | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2015 | poor | high | very low |
| Whole site assessed? | State assessed by | Accuracy of information | |
| yes | habitat | medium | |
| State (condition of the trigger species' habitats) | |||
|---|---|---|---|
| Habitat | Quantity (% remaining) | Quality (% carrying capacity) | Result |
| Grassland | - | poor (40–69%) | poor |
| Forest | - | moderate (70–90%) | moderate |
| Wetlands (inland) | - | moderate (70–90%) | moderate |
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Energy production and mining | happening now | some of population/area (10–49%) | rapid decline (>30% over 3 generations) | high |
| Residential and commercial development | happening now | some of population/area (10–49%) | slow decline (1–10% over 3 generations) | medium |
| Response (conservation actions taken for the trigger species and/or their habitats) | |||
|---|---|---|---|
| Designation | Planning | Action | Result |
| Little/none of area covered (<10%) | No management planning has taken place | Very little or no conservation action taking place | very low |
| Habitat | % of IBA | Habitat detail |
