Site details
Site description: The site boundary is based upon a seaward extension of 25 km around Dent de Saint-Vincent to encompass high use and transit areas of IBA threshold numbers of Gould's Petrel based upon a 2007 population estimate of 4,000 - 8,000 breeding pairs from Spaggiari, J., Chartendrault, V. and Barre, N. (2007) Zones importantes pour la conservation des oiseaux de Nouvelle-Caledonie. Societe caledonienne d'ornitholoie - SCO et BirdLife International. Noumea, Nouvelle-Caledonie. 216pp; a seaward extension of 25 km around Massifs du Grand Sud - entre le mont Humboldt et la rivière Bleue to encompass high use and transit areas of IBA threshold numbers of Gould's Petrel based upon a 2004 population estimate of 1,000 - 10,000 breeding pairs from Brooke, M.
