Monumento Natural Isla Cachagua


IBA Justification

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
Humboldt Penguin Spheniscus humboldti VU breeding (2003) 600 birds A1, A4ii
Humboldt Penguin Spheniscus humboldti VU breeding (2016–2020) 8–250 birds A1
Brown Pelican Pelecanus occidentalis LC breeding (2001–2002) 400–3,000 pairs A1
Peruvian Pelican Pelecanus thagus NT resident (2016–2020) 6–800 birds B1a
Guanay Cormorant Leucocarbo bougainvilliorum NT resident (2016–2020) 30–1,200 birds B1a

IBA Conservation

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2020. The most recent assessment (2020) is shown below.

IBA conservation assessment
Year of assessment State Pressure Response
2020 good high high
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
Marine Coastal/Supratidal good (>90%) good (>90%) good

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Invasive and other problematic species and genes happe­ning now most of popul­ation/area (50–90%) slow decline (1–10% over 3 gener­ations) high
Climate change and severe weather likely in long term (>4 years) most of popul­ation/area (50–90%) slow decline (1–10% over 3 gener­ations) medium
Biological resource use happe­ning now few indivi­duals/small area (<10%) slow decline (1–10% over 3 gener­ations) low
Human intrusions and disturbance happe­ning now few indivi­duals/small area (<10%) slow decline (1–10% over 3 gener­ations) low
Pollution 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
Whole area (>90%) covered by appropriate conservation designation A compre­hensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species Substantive conservation measures are being implemented, but these are not compre­hensive and are limited by resources and capacity high
