Site details


Site description: McKean Island is a low and flat, circular-shaped, coral island surrounded by a fringing reef.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that meets the thresholds for at least one criterion described in the Global Standard for the Identification of KBAs.
Additional biodiversity: A seabird colony with good numbers of a range of species.During the 1960s McLean Island was one of the flagship islands of the Phoenix group, supporting diverse and important populations of seabirds
Delineation rationale: 2012-12-17 (BL Secretariat): original polygon clipped to hi-res coastline following identification in October 2012 of new marine IBA offshore this site; site area consequently changed from 47 ha to 56 ha.

Habitats


Summary of habitats in KBA: The island is a reef-fringed, essentially sea-level or very slightly elevated emergent coral reef, with accumulations of coral or algal debris and some phosphate from seabird droppings.

Threats


Summary of threats to biodiversity at KBA: Recent accidental introduction of Asian Rats is correlated with a decline in seabird numbers, and evidence of reduced seabird productivity, on the island.
