Cleidion lemurum is an endemic shrub of New Caledonia only known from Lindéralique at the calcareous rocks of Hienghène in the northern east part of Grande Terre. This species was first observed by Balansae in 1871 and recent prospection has managed to relocate the species. It is found in undergrowth scrubby vegetation on calcareous rocks up to 10 m asl. It is known of a single population, with a population estimated to be less than 250 mature individuals. The species is threatened by invasive plants (coffee plants), land clearing and uncontrolled bushfires. Its area of occurrence (EOO) and area of occupancy (AOO) are both estimated to be 8 km², while the number of locations is estimated to be one. Therefore, C. lemurum is assessed as Critically Endangered (CR) B1ab(iii,v)+2ab(iii,v); C2aii, with an estimated decline of habitat quality and number of mature individuals.

Geographical area


C. lemurum is endemic to New Caledonia where it is only known from the calcareous rocks of Hiengène at Lindéralique, in the north east of Grande Terre.

Population


This species was found during a recent prospection 147 years after its first observation. Total population size is unknown but field observations indicate a small population with a small regeneration.

Habitat


C. lemurum occurs in undergrowth scrubby vegetation on calcareous rocks up to 10 m asl.

Threats


The main threats identified are invasive plants (coffee plants), land clearing and uncontrolled bushfires.

Conservation


C. lemurum is not protected by legislation in New Caledonia. This species should be included in the regional legislation for a better protection of the species. It does not occur in any protected area but it is present in an UNESCO World Heritage site, also considered tabou by the local population. However this species should be included in the regional legislation for a better protection of the species and ex situ and in situ conservation efforts are urgently needed, in particular : ensuring the follow-up of the known sub-populations. It is also recommended to make awarness amongs the local population and inform the DSCGR (emergency services), responsible for the coordination of the firefighting effort, on the presence of the species in the concerned area.
