Red List Status -Critically Endangered (CR) , assessed in 05/04/2018
Protected species -in Northern Province
Macaranga latebrosa is a narrowly endemic shrub to Art island, at Belep islands, in the north of Grande Terre. It is known from only a single subpopulation loacted in dense humid forest on ultramafic substrate at an altitude of 200-300 m asl. Its extent of occurrence (EOO) and area of occupancy (AOO) are both estimated to be 16 km², while the species is known from a single location. The main threats impacting this species are bushfires which are severe in Belep. Using criteria B, M. latebrosa is considered Critically Endangered Critically Endangered (CR) B1ab(iii,v) with an estimated decline of habitat quality and number mature individuals.
M. latebrosa is endemic species of New Caledonia where it is restricted to Art island, at Belep islands, in the north of Grande Terre. It is known from the northern and southern plateau of Art island.
Population size is unkown but field observations indicate a small population size.
M. latebrosa is found in dense humid forest on ultramafic substrate at an altitude range of 200-300 m asl.
The main threats identified are uncontrolled bushfires which are severe in Belep and potential impacts of the future minig activities.
M. latebrosa is not protected by legislation and it does not occur in any protected area. This species should be included in the regional legislation for a better protection of the species. This species would benefit from ex situ and in situ emergency conservation actions and also awarness amongs the local population. 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.
