Red List Status -

Vulnerable (VU) , assessed in 25/06/2020

Phyllanthus quintuplinervis is a shrub of 1-3 m high, endemic of New Caledonia and restricted to the central part of Grande Terre, from Nétéa to Bogota. This species occurs in maquis and undergrowth forests on ultramafic substrates up to 700 m asl. The main identified threats are linked to habitat damage by uncontrolled bushfires and future mining activities at Boulinda. Its extent of occurrence (EOO) and area of occupancy (AOO) are respectively estimated to be of 1,164 km² and 32 km² while the number of locations is estimated to be 7. Using criterion B and with the estimation of a continuous decline of its habitat quality and number of mature individuals, Phyllanthus loranthoides var. loranthoides is assessed as Vulnerable (VU) B1ab(iii,v)+2ab(iii,v).

Conservation


Phyllanthus genus is protected by legislation in Province Nord. Phyllanthus quintuplinervis does not occur in any protected area. It is recommended to inform the DSCGR (emergency services), responsible for the coordination of the firefighting effort on the presence of the species in the concerned areas. It is moreover suggested to realise field surveys at Mé Adéo and Thio (Ouroué) to better estimate its distribution range and population size.
