Vulnerable (VU) , assessed in 23/07/2015

Endemic shrub of New Caledonia, Pittosporum morierei is located on massifs of central Grande Terre. P.morierei occurs as isolated individuals in mid altitude dense humid forest on schist and greywacke at an altitudinal range 250-800 m asl. Its area of occupancy is 72 km² for an extent of occurrence of 2,170 km². Population size is not precisely known, but this one could be greater than 10,000 mature individuals. On 7 localities surveyed, habitat degradation of P. morierei was observed to be exclusively due to invasive animal species, specifically rusa rusa deer (Rusa timorensis) (Rusa timorensis) and feral pigs. Under criteria B, it seems suitable to classify P.morierei under Vulnerable (VU) B1ab(iii)+2ab(iii).

Geographical area


Endemic shrub of New Caledonia, P. morierei is located on massifs of central of Grande Terre.

Population


Population size is not precisely known, but this species could be greater than 10,000 mature individuals. Field surveys emphasize a weak natural regeneration.

Habitat


P.morierei occurs as isolated individuals in mid altitude dense humid forest on schist and greywacke at an altitudinal range 250-800 m asl.

Threats


Main identified threats are linked to habitat damaging by rusa rusa deer (Rusa timorensis) (Rusa timorensis) and pigs, two of the most important invasive species in New Caledonia. Introduced in the 1880's, rusa rusa deer (Rusa timorensis) are now perfectly adapted to New Caledonian habitats.

Conservation


Unprotected species by legislation, P. morierei is however known from réserve de nature sauvage du massif de l’Aoupinié.
