Red List Status -

Endangered (EN) , assessed in 07/04/2017

Phelline barrierei is a newly described, endemic shrub or tree of New Caledonia, restricted to the the north west area fo Grande Terre. It is only known from two subpopulations: Boulinda and Paéoua. It occurs in dense humid forest on ultramafic substrate at an altitudinal range from 500 to 1,300 m asl. The main impact identified comes from potential mining activites on Paéoua and Boulinda. Bushfires and invasive species contribute to the habitat degradation. Its area of occupation (AOO) and extent of occurrence (EOO) being both estimated to 24 km², while the number of locations are estimated to be two. P. barrierei is therefore assessed as Endangered (EN) with criteria B1ab(iii,v)+2ab(iii,v) with an estimated continuing decline of habitat quality and number of mature individuals.

Geographical area


P. barrierei is endemic to New Caledonia, where it is restricted to the northwestern area of Grande Terre. It is only known from two subpopulations: Boulinda and Paéoua.

Population


Population size is unknown.

Habitat


P. barrierei occurs in dense humid forest on ultramafic substrate at an altitudinal range from 500 to 1,300 m asl.

Threats


The main impact identified comes from potential mining activites on Paéoua and Boulinda. Bushfires and invasive species contribute to the habitat degradation.

Conservation


Unprotected by legislation, Phelline barrierei is not present in any protected areas. This species would benefit from ex situ and in situ emergency conservation actions. It is proposed to ensure the follow-up of known subpopulations, to preserve a viable population on delimited perimeters. Moreover, it is suggested to raise awareness on this species amongst local stakeholders and informed the local authority responsible for the coordination of the firefighting effort about the presence of the species in the concerned areas. And prospections in other south western massifs is needed to better estimate the size of the population and its status.
