Data Zone
The site was identified as internationally important for bird conservation in 2007 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 |
|---|---|---|---|---|
| Maguari Stork Ciconia maguari | LC | resident (2005) | 800 individuals | A4i |
| Jabiru Jabiru mycteria | LC | resident (2005) | 500 individuals | A4i |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2011) is shown below.
| IBA conservation status | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2011 | not assessed | very high | very low |
| Whole site assessed? | State assessed by | Accuracy of information | |
| no | unset | unknown | |
| Pressure (threats to the key species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Natural system modifications | happening now | whole population/area (>90%) | moderate deterioration (10–30% in 3 generations) | very high |
| Agricultural expansion and intensification | happening now | most of population/area (50–90%) | rapid deterioration (>30% over 3 generations) | very high |
| Human intrusions and disturbance | past (and unlikely to return) and no longer limiting | some of population/area (10–49%) | no deterioration (<1% over 3 generations) | low |
| Response (conservation actions taken for the key species and/or their habitats) | |||
|---|---|---|---|
| Designation | Planning | Action | Result |
| Little/none of site covered (<10%) | No management planning has taken place | Very little or no conservation action taking place | very low |
