Pycnandra fastuosa is an endemic tree of New Caledonia growing up to 20 m high. It is distributed across the Grande Terre from low hills in the south of Grande Terre to the high mountains such as Mount Kouakoué, Mount Mou, and the Koniambo massif in the north.This species is probably not well enough collected and may have a wider range of distribution than the actual distribution. This species is found in humid forests on ultramafic substrate at an altitudinal range 200-1,500 m asl. This specie is a forest species and has no aparent threat. The Extent of Occurrence (EOO) ranges between to 5,000 km² and 10,000 km² and the Area of Occupancy (AOO) of 112 km² and 500 km², P. fastuosa is not thought to approach the requirements for listing as threatened. It is listed as Least Concern (LC).

Geographical area

Pycnandra fastuosa is endemic to New Caledonia where it is distributed across the Grande Terre from low hills in the south of Grande Terre to the high mountains such as Mount Kouakoué, Mount Mou, and the Koniambo massif in the north. This species is probably not well enough collected and may have a wider range of distribution than the actual distribution.

Population

Population size is unknown. However this species is frequently seen during field prspections in the Grand Massif Sud but it is not always in fertile stage. Therefore herbarium collections were not made (person.comm Munzinger, J.).

Habitat

Pycnandra fastuosa is found in humid forests on ultramafic substrate at an altitudinal range 200-1,500 m asl.

Threats

Pycnandra fastuosa does not seem to be threatened as it occurs in deep forest areas.

Conservation

Pycnandra fastuosa is not protected by legislation in New Caledonia and it does occur in several protected areas: Barrage de Yaté, Côte Oubliée, Forêt cachée, Forêt de Saille, Foret Nord, Haute Dumbéa, la Dumbéa, Massif du Kouakoué,, Mont Do, Mont Mou, Rivière bleue. This species is rarely seen fertile and there is a need to realise field surveys and to collect further fertile and non fertile specimens to better estimate its population size and status.
