Taxonomy
Alphandia resinosa
Red List Status -
Critically Endangered (CR) , assessed in 05/04/2018Protected species -
in Northern ProvinceAlphandia resinosa is a narrowly endemic shrub or small tree to Art island at Belep in the north of Grande Terre. It is known from only a single subpopulation located in dense humid forest on ultramafic substrate at an altitude of approximately 250 m asl. The main threats impacting this species are bushfires which are severe in Belep. Its area of occupancy (AOO) and extent of occurrence (EOO) being both estimated to 12 km², while the species is known from a single location. A. resinosa is therefore considered Critically Endangered (CR) B1ab(iii,v) with an estimated decline of habitat quality and number mature individuals.
Geographical area
A. resinosa is endemic to New Caledonia restricted in Art island, at Belep in the northpart of Grande Terre. It is only known from the northern and southern plateau of Art island.
Population
Population size is unknown.
Habitat
A. resinosa is found in dense humid forest on ultramafic substrate at an altitude of approximately 250 m asl.
Threats
The main threats identified are uncontrolled bushfires which are severe in Belep and potential impacts of the future mining activities.
Conservation
A. resinosa is not protected by legislation in New Caledonia and it does not occur in a 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 amongst 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.
