Site details
Site description: This Marine IBA is identified using seaward extensions around breeding colonies. It originates from the Japan Exclusive Economic Zone (EEZ) and falls within the Pacific, Northwest FAO ocean region. The site covers an area of 903 km2 and is 91 km away from the closet coastline. The depth ranges from 2 to 458 m, mean annual sea surface temperature falls between 21.78 and 22.19 °C and mean annual chlorophyll-a concentrations found to range between 0.34 and 0.37 mg/m3.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance because it meets one or more previously established criteria and thresholds for identifying sites of biodiversity importance (including Important Bird and Biodiversity Areas, Alliance for Zero Extinction sites, and Key Biodiversity Areas)
Additional biodiversity: 2 species trigger IBA criteria at this Marine IBA. Seaward extensions around breeding colony; Danjo islands include key near-colony areas for breeding populations of Streaked Shearwater (LC) and Japanese Murrelet (VU).
Delineation rationale: Site identified by applying a colony extension to SitRecId - 15173, 15173
