Red List Status -

Critically Endangered (CR) , assessed in 10/05/2016

Pycnandra belepensis is an endemic shrub or small tree of New Caledonia restricted to Ile Art, where it grows on the northern plateau. It is found in dense humid forest on ultramafic substrate at an altitude of 220-260 m asl. Its area of occurrence (EOO) and area of occupancy (AOO) are respectively 2 km² and 12 km², while the species is known from a single location. The main identifed threat are uncontrolled fires as well as the grazing of cattle that allow us to project a continuous decline in the quality of habitat and number of mature individuals. Using criteria B, P. belepensis qualifies Critically Endangered (CR) B1ab(iii,v)+2ab(iii,v).

Geographical area


Pycnandra belepensis is an endemic shrub or small tree of New Caledonia restricted to Ile Art, where it grows on the northern plateau.

Population


Population size is unkown.

Habitat


Pycnandra belepensis is found in dense humid forest on ultramafic substrate at an altitude of 220-260 m asl.

Threats


Pycnandra belepensis may be impacted by uncontrolled bushfires, grazing of cattle and future mining activities. The only known subpopulation of this species is situated on mining concession and may constitute an additionnal threat.

Conservation


P. belepensis is not protected by legislation. It does not occur in any protected area. This species would benefit from ex-situ and in-situ emergency conservation actions. It is proposed to ensure the follow-up of the only known sub-population and to preserve a viable population on delimited perimeters. It is also recommended to inform the DSCGR (emergency services), responsible for the coordination of the firefighting effort, on the presence of the species in the concerned area.
