Denhamia fournieri is an endemic shrub of New Caledonia, which under current taxonomic delimitation, is largely distributed in Grande Terre as well as in Belep island.This species is poorly known and very difficult to distinguish. Within that complex genus, Denhamia fournieri seems to have a taxonomic impediment. It could be spilled into several distinct species and could be found in areas threatened by fires, mining activities, and invasive species. This taxon is insufficiently collected and not well known. Denhamia fournieri is therefore assessed as Data Deficient (DD) for taxonomic reasons.

Geographical area


D. fournieri is endemic to New Caledonia, where under current delimitation is largely distributed in Grande Terre as well as in Belep islands.

Population


Population size is unknown.

Habitat


D. fournieri seems to occurs in dense humid forest and rarely in shrubland on ultramafic and volcano-sedimentary rocks, up to 1,100 m asl.

Threats


It was collected in an area potentially impacted by fires, invasive species (feral pigs (Sus scrofa), Rusa deer (Rusa timorensis) and mining activities (Pinpin, Kouaoua, Tiebaghi, Cap Bocage and Goro).

Conservation


D. fournieri is not protected by legislation in Province Nord and does occur in several protected area: Aoupinié, Dumbéa, Ouen toro et Vallée de la Thy. Taxonomic clarification is urgently needed on this probable complex of taxa in order to be able to assess its extinction risk.
