Pycnandra glabella is concentrated in the southern part of Grande Terre in New Caledonia, from Port Boisé to Plaine des Lacs as well as occurring in two isolated populations in the central-east part of the island. It occurs primarily in humid forest on ultramafic substratse between 250 and 500 m asl. Recurrent bushfires and mining activities are the main identified threats. Its area of occupancy (AOO) and extent of occurrence (EOO) are respectively estimated to be 28 km² and 1,434 km². Additional populations potentially may exist, but this assessment is precautionarily based on the six known locations. Pycnandra glabella is therefore considered Vulnerable (VU) according to criteria B1ab(i,ii,iii,v)+B2ab(i,ii,iii,v) with a continuing decline of all sub-criteria.

Geographical area

Pycnandra glabella is an edemic shrub or tree up to 8m tall, concentrated in the southern part of Grande Terre in New Caledonia, from Port boisé to Plaine des Lacs and two isolated populations are in central-east part of the island .

Population

It is known from seven sub-populations: Moneo, Bogota, Grand Lac, Grand Kaori, Goro, Port Boisé. Additional populations may exist in suitable forests along the eastern coast, but those areas are still undersampled.

Habitat

Pycnandra glabella is found in dense humid forest on ultramafic substrate at an altitudinal range 250-500 m asl.

Threats

Some of the lowest subpopulations may be threatened by bushfires (Moneo, Bogota, Port boisé) or ongoing mining activities : Goro (VALE) and habitat degradation due to past mining activites (Bogota).

Conservation

Unprotected by legislation, Pycnandra glabella does not occur in any protected area. It is recommended to prospect more systematically this species.
