Pycnandra fastuosa is an endemic tree up to 20m tall widespread along Grande Terre from low hills in the south of Grande Terre to the high mountains such as Mount Kouakoué, Mount Mou, and the Boulinda massif in the north. It is found in humid forests on ultramafic substrates at an altitudinal range 200-1500 m asl. Molecular studies have indicated that it might be possible to divide populations into two taxa of suitable rank. Pycnandra fastuosa is therefore assessed as Data Deficient (DD) for taxonomic reasons.
Geographical area
Pycnandra fastuosa is an endemic tree up to 20m tall widespread along Grande Terre from low hills in the south of Grande Terre to the high mountains such as Mount Kouakoué, Mount Mou, and the Boulinda massif in the north.
Population
This species is quite common. It is known from 20-22 sub-populations.
Habitat
Pycnandra fastuosa is found in humid forests on ultramafic substrates at an altitudinal range 200-1500 m asl. It has even been able to colonise small pockets of ultramafic soil north of Farino.
Threats
Some subpopulations may be threatened by mining activities: Goro (VALE) However, this species does not seem globally threatened.
Conservation
Unprotected species by legislation, Pycnandra fastuosa is found in eleven protected areas : Forêt de Saille, Mont Do, Foret Nord, Montagne des sources, Haute Yaté, Barrage de Yaté, Haute Dumbéa, Massif du Kouakoué, la Dumbéa, Rivière bleue, Pic du grand Kaori. Taxonomic studies are recommanded to confirm the two taxa.
