Pittosporum coccineum is an endemic shrub of New Caledonia, which under current delimitation of taxon, is distributed on the northern Grande Terre, on both west and east coasts and in Belep. Nevertheless according to current phylogenetic studies, populations located on the west coast, the east coast and Belep would constitute three distinct entities. P. coccineum is classified under Data Deficient category until taxonomic species delimitations are clarified.

Geographical area


P. coccineum is an endemic shrub of New Caledonia present on the northern Grande Terre, on both west and east coasts and in Bélep.

Population


Population size is unknown.

Habitat


P. coccineum is found on all kind of substrates, in dense humid forest as in dry forest.

Threats


Due to its ecology and geographic range, P. coccineum could be affected by the majority of inventoried threats in New-Caledonia including fire, rusa deer (Rusa timorensis), mining activities, animal husbandry and urbanisation.

Conservation


P. coccineum is protected by legislation in Province Sud. This species occurs also in one protected area of Province Nord : la réserve naturelle intégrale de la baie de Nékoro. In order to remove taxonomic doubts and thus assess extinction risk of P. coccineum, it is urgent to finalize work on its phylogenesis and to describe taxa which are included in current species complex. According to Jean-Marie Veillon, highlighted heterogeneity could be the result of inclusion of P. vieillardii under P. coccineum, which has quite the same floral morphology but who is different regarding the size of flower.
