Data Zone
The site was identified as internationally important for bird conservation in 2019 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 |
|---|---|---|---|---|
| Spectacled Duck Speculanas specularis | NT | resident (2015–2019) | 10–30 birds | A3, B1a |
| Chilean Pigeon Patagioenas araucana | LC | resident (2015–2018) | 2–70 birds | A3 |
| Austral Parakeet Enicognathus ferrugineus | LC | resident (2015–2018) | 2–82 birds | A3 |
| Dusky Tapaculo Scytalopus fuscus | LC | resident (2015–2018) | 1–2 adults | A3 |
| White-throated Treerunner Pygarrhichas albogularis | LC | resident (2015–2018) | 1–16 birds | A3 |
| Thorn-tailed Rayadito Aphrastura spinicauda | LC | resident (2015–2019) | 1–15 birds | A3 |
| Des Murs's Wiretail Sylviorthorhynchus desmurii | LC | resident (2015–2019) | 1–3 birds | A3 |
| Patagonian Tyrant Colorhamphus parvirostris | LC | non-breeding (2015–2019) | 1–6 birds | A3 |
| Fire-eyed Diucon Xolmis pyrope | LC | resident (2015–2019) | 1–14 birds | A3 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2019. The most recent assessment (2019) is shown below.
| IBA conservation assessment | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2019 | good | high | low |
| Whole site assessed? | State assessed by | Accuracy of information | |
| no | habitat | good | |
| State (condition of the trigger species' habitats) | |||
|---|---|---|---|
| Habitat | Quantity (% remaining) | Quality (% carrying capacity) | Result |
| Artificial/Aquatic & Marine | good (>90%) | good (>90%) | good |
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Climate change and severe weather | happening now | whole of population/area (>90%) | slow decline (1–10% 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10%) | A management plan exists, but it is out of date or not comprehensive | Very little or no conservation action taking place | low |
| Habitat | % of IBA | Habitat detail |
