Red List Status -

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

Phyllanthus loranthoides var. loranthoides is an endemic small shrub of New Caledonia restricted to the far north of Grande Terre, from Gatope to pic Yago, as well as in Belep islands. This subspecies occurs in maquis on ultramafic and volcano-sedimentary substrates at an altitude range of 10 and 1,100 m asl. The main identified threats are linked to habitat damage by uncontrolled bushfires and mining activities at Tiebaghi. Its extent of occurrence (EOO) and area of occupancy (AOO) are respectively estimated to be of 3,957 km² and 72 km² while the number of locations is estimated to be 9. 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(ii,iii,v)+2ab(ii,iii,v).

Geographical area

Conservation


Phyllanthus genus is protected by legislation in Province Nord. Phyllanthus loranthoides var. loranthoides 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 Poum and Canala to update and better estimate its distribution range and population size.
