Planchonella minutiflora Munzinger & Swenson

Red List Status -

Endangered (EN) , assessed in 29/11/2019

Protected species -

in Northern Province

Planchonella minutiflora is an endemic shrub of New Caledonia, where it is restricted to the northwest of Grande Terre. It occurs in shrubland on ultramafic substrate up to 500 m asl. The main threats to this species are bushfires, urbanisation, as well as the indirect impacts of mining activities. Its extent of occurrence (EOO) and area of occupancy (AOO) are 67 and 16 km², respectively, and the number of locations is estimated to be three. Therefore, P. minutiflora is listed as Endangered (EN) under criteria B1ab(iii,v)+B2ab(iii,v).

Geographical area

P. minutiflora is endemic to New Caledonia, where it is restricted to the northwest of Grande Terre, from Mt. Kaala to Poum.


Population size is unknown, but field observations indicate that this species is scarce.


This shrub grows in low elevation shrubland ('maquis') on ultramafic substrate up to 500 m asl.


The main threat to this species is posed by bushfires and urbanisation at the foot of the massifs. Mining activities can also indirectly impact it through the opening of trails and landfill sites.


P. minutiflora is protected by legislation in Province Nord, but it doesn't occur in any protected areas. This species would benefit from ex-situ and in-situ emergency conservation actions. It is proposed that monitoring should occur to ensure the persistence of the known population. It is also recommended to inform the DSCGR (government department overseeing firefighting actions) on the presence of the species in the concerned areas. Finally, prospection is recommended in the northwest of Grande Terre, where it is potentially more widely distributed.
