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 |
|---|---|---|---|---|
| Humboldt Penguin Spheniscus humboldti | VU | breeding (2015–2019) | 6–100 birds | A1, B3b |
| Peruvian Diving-petrel Pelecanoides garnotii | NT | non-breeding (2015–2019) | 9–250 birds | A1, B3b |
| Peruvian Pelican Pelecanus thagus | NT | resident (2015–2019) | 12–25 birds | B3b |
| Peruvian Booby Sula variegata | LC | breeding (2003) | 18,000 birds | A4, B3b |
| Red-legged Cormorant Poikilocarbo gaimardi | NT | resident (2015–2019) | 4–6 birds | B3b |
| Guanay Cormorant Leucocarbo bougainvilliorum | NT | breeding (2015–2019) | 4–45 birds | B1a, B3b |
| Neotropical Cormorant Nannopterum brasilianum | LC | breeding (2003) | 50 birds | B3b |
| Kelp Gull Larus dominicanus | LC | breeding (2003) | 2,000 birds | B3b |
| Inca Tern Larosterna inca | NT | breeding (2015–2019) | 3–12 birds | B3b |
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 | very 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 |
| Marine Coastal/Supratidal | - | good (>90%) | good |
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Energy production and mining | likely in short term (<4 years) | whole of population/area (>90%) | rapid decline (>30% over 3 generations) | very high |
| Human intrusions and disturbance | likely in short term (<4 years) | whole of population/area (>90%) | rapid decline (>30% over 3 generations) | very high |
| Climate change and severe weather | likely in long term (>4 years) | whole of population/area (>90%) | slow decline (1–10% over 3 generations) | medium |
| Biological resource use | happening now | few individuals/small area (<10%) | moderate decline (10–30% over 3 generations) | low |
| 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 | Substantive conservation measures are being implemented, but these are not comprehensive and are limited by resources and capacity | low |
| Habitat | % of IBA | Habitat detail |
|---|---|---|
| Marine Coastal/Supratidal | major (>10) | |
| Shrubland | major (>10) | Arid lowland scrub |
| Land use | % of IBA |
|---|---|
| nature conservation and research | major (>10) |
