IBA Justification

The site was identified as important in 2020 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species'):
Species Current IUCN Red List Category Season Year(s) Population estimate at site IBA criteria met
Southern Rockhopper Penguin Eudyptes chrysocome VU resident 2016-2020 301 individuals A1
Magellanic Penguin Spheniscus magellanicus LC resident 2016-2020 67-1,110 individuals B1a
Sooty Shearwater Ardenna grisea NT breeding 2016-2020 1,000-100,000 individuals B1a
Striated Caracara Phalcoboenus australis NT resident 2006 present A1, A2

State (condition of the trigger species' habitats)
Habitat Habitat detail Reference area (ha) Actual area (ha) Habitat quantity (% remaining) Habitat quality (carrying capacity) Result
Grassland 45000 45000 - good (> 90%) favourable
Marine Coastal/Supratidal 10700 10700 - good (> 90%) favourable
Wetlands (inland) 5000 5000 - good (> 90%) favourable

Pressure (threats to the trigger species and/or their habitats)
Threat level 1 Threat level 2 Timing Scope Severity Result
Residential and commercial development tourism and recreation areas happening now some of area/population (10-49%) no or imperceptible deterioration low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected-area designation Management planning Other conservation action Result
Whole area of site (>90%) covered by appropriate conservation designation No management plan exists but the management planning process has begun Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity medium
