Site details
Site description: This Marine IBA is identified using seaward extensions around breeding colonies. It originates from the Norfolk Island (to Australia) Exclusive Economic Zone (EEZ) and falls within the Pacific, Southwest FAO ocean region. The site covers an area of 11653 km2 and is 704 km away from the closet coastline. The depth ranges from 0 to 3104 m, with a mean annual wind speed of 1.99 m/s, mean annual sea surface temperature falls between 20.73 and 21.28 °C and mean annual chlorophyll-a concentrations found to range between 0.13 and 0.29 mg/m3.
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: 6 species trigger IBA criteria at this Marine IBA. Seaward extensions around breeding colonies; Phillip Island (Norfolk Island), Norfolk Island include key near-colony areas for breeding populations of Blue Noddy (LC) 1500-24000 individuals, Providence Petrel (VU) 20-100 individuals, White-necked Petrel (VU) 30-30 individuals, Wedge-tailed Shearwater (LC) 400000-2000000 individuals, Common White Tern (LC) and Red-tailed Tropicbird (LC) 600-600 individuals.
