Data Zone
The site was identified as internationally important for bird conservation in 2010 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 |
|---|---|---|---|---|
| Peruvian Pelican Pelecanus thagus | NT | non-breeding (-) | 400 birds | A1 |
| South American Tern Sterna hirundinacea | LC | resident (-) | 4,000 birds | A4i |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2021) is shown below.
| IBA conservation assessment | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2021 | very poor | medium | very low |
| Whole site assessed? | State assessed by | Accuracy of information | |
| yes | habitat | good | |
| State (condition of the trigger species' habitats) | |||
|---|---|---|---|
| Habitat | Quantity (% remaining) | Quality (% carrying capacity) | Result |
| Artificial/Terrestrial | poor (40–69%) | poor (40–69%) | very poor |
| Marine Intertidal | moderate (70–90%) | good (>90%) | moderate |
| Marine Neritic | good (>90%) | good (>90%) | good |
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Agricultural expansion and intensification | happening now | some of population/area (10–49%) | slow decline (1–10% over 3 generations) | medium |
| Residential and commercial development | happening now | few individuals/small area (<10%) | slow decline (1–10% 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 | Very little or no conservation action taking place | very low |
| Habitat | % of IBA | Habitat detail |
|---|---|---|
| Marine Intertidal | major (>10) | |
| Marine Neritic | major (>10) | |
| Artificial/Terrestrial | - | Arable land; Forestry and agro-industrial plantations |
