Red List Status -

Near Threatened (NT) , assessed in 30/09/2016

Clinosperma vaginata is an endemic solitary, understory to emergent tree palm, that is widespread and common in humid forest in south Grande Terre in New Caledonia. Clinosperma vaginata occurs in dense humid forest on soils derived from ultramafic rocks from 110-720 m asl. The main impacts identified comes from invasive species (destruction of seeds by rats and destruction of individuals by wild pigs). Population size is unknown but observation fields noted an abundance of the population with natural regeneration. Therefore, this species does not seem directly threatened. The number of locations, based on habitat degradation as the main threat, is estimated to be 10-13. Its area of occupancy (AOO) and extent of occurrence (EOO) being respectively estimated to 40 and 1,680 km², Clinosperma vaginata is considered Near Threatened (NT) close to VU B1ab(iii)+2ab(iii) with a decline of habitat quality and a number of locations close to 10.

Geographical area


Clinosperma vaginata is an endemic palm tree, that is widespread and common in humid forest in south Grande Terre in New Caledonia.

Population


Population size is unknown but observation fields noted an abundance of the population on the stations observed.

Habitat


Clinosperma vaginata occurs in dense humid forest on soils derived from ultramafic rocks from 110-720 m asl.

Threats


This species does not seem globally threatened. The potential impacts identified comes from invasive species : destruction of seeds by rats and destruction of individual and habitats by wild pigs and rusa deer (Rusa timorensis). It should also be noted that due to low germination rates of seed, this species can be sensitive to illegal removals in their natural environment.

Conservation


Clinosperma vaginata is not protected by the local legislation but it occurs in three protected areas : Haute Yaté, Massif du Kouakoué, Parc de la Rivière bleue.
