Sarcomelicope glauca is a shrub endemic to New Caledonia, only known from one locality on Ile des Pins (Pic N'Ga). It occurs in shrubland on ultramafic substrate up to 200 m asl. Its area of occupancy (AOO) and extent of occurrence (EOO) are both equal to 4 km². The main identified threat is habitat degradation by uncontrolled bushfires. This species is therefore listed as Critically Endangered (CR) under criteria B1ab(iii,v)+2ab(iii,v) with a decline of habitat quality and number of mature individuals.

Geographical area


S. glauca is endemic to New Caledonia, where it is found only on Ile des Pins, at Pic N'Ga.

Population


Only one population (Pic N'Ga) has been identified, its size is unknown, but field observations indicate the species is rather abundant on the summit and along the river.

Habitat


S. glauca occurs in shrubland on ultramafic substrate up to 200 m asl.

Threats


The main identified threat is habitat degradation by uncontrolled bushfires.

Conservation


S. glauca is protected by legislation in Province Sud, 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 to ensure the follow-up of known sub-populations, to preserve a viable population on delimited perimeters. It is recommended to inform the DSCGR (emergency services) and local Management Committee on the presence of the species in the concerned areas. Moreover a protected area should be etablished in Pic N'Ga.
