Crossosperma velutina is an endemic tree (3-15 m high) of Grande Terre in New Caledonia. It is found in altitudinal vegetation, forest on volcano-sedimentary substrate in the north and on ultramafic in the south between 150-700 m asl. The northern and southern subpopulations of this taxon appear to be genetically different. Further taxonomic clarification is required before this species can be assessed hence it is considered as Data Deficient (DD).

Geographical area


Crossosperma velutina is an endemic tree of Grande Terre in New Caledonia with a discontinious distribution in the south (from Forêt Nord to Rivière Bleue) and in the north east (from Mandjelia et col d'Amoss).

Population


Population size is unknown.

Habitat


It is found in humid forest on volcano-sedimentary substrate in the north east and on ultramafic in the south at an altitude range of 150-700 m asl.

Threats


This species may be threatened by bushfires at col d'Amoss.

Conservation


This species is unprotected by legislation. Crossosperma velutina is found in two protected areas : Foret Nord and Rivière Bleue. This species is actually subject to a conservation plan program at VALE NC and some plants have been tranfered to Parc de la Rivière Bleue and Pic du Grand Kaori. However, there is a need to collect more fertile herbarium specimens from the northern and souther locality in order to clarify the taxonomic status of this taxon.
