Clinosperma macrocarpa is a solitary, moderate, understory to canopy, tree palm endemic of New Caledonia, known only from one population on the eastern part of Mt. Panié in northeast of Grande Terre. Clinosperma macrocarpa occurs in dense humid forest on soils derived from schistose rocks from 491-585 m asl. The population is estimated to 52 mature individuals and the threats identified are the impacts of invasive species (rats, rusa deer (Rusa timorensis) and pigs) and seed collections. This species has been subject to an action plan for in-situ conservation actions. With an area of occupancy (AOO) and extent of occurrence (EOO) being both estimated to 8 km², Clinosperma macrocarpa is still considered Critically Endangered (CR) using criteria B1ab(iii,v)+2ab(iii,v), C2a(ii) with an estimation of one location and a decline of habitat quality and number of individuals.

Geographical area


Clinosperma macrocarpa is known only from one population on the eastern part of Mt. Panié in north-east of Grande Terre in New Caledonia.

Population


The population is estimated to 52 mature individuals in a single population.

Habitat


Clinosperma macrocarpa occurs in dense humid forest on soils derived from schistose rocks from 491-585 m asl.

Threats


The threats identified are the impacts of invasive species (rats, rusa deer (Rusa timorensis) and pigs) and seed collections. Indeed observations report a selective behaviour of rats to select viable seeds. Also an individual has been discovered equipped with a net to collect seeds in 2015.

Conservation


Clinosperma macrocarpa is protected by legislation in Province Nord and in Province Sud and it occurs in one reserve: Mont Panié. This species is subject to an action plan and management plan by Noe, a non governmental organization and a local association that manages the reserve of Mt Panié, Dayu Biik. Their work has focused on phenological monitoring from 2014 to end of 2015, characterization of the predation, control of rats (observations report a selective behavior of rats to select the good and viable seeds.), surveying, vitro culture protocol (its germination is not yet mastered following IAC research works and the maturity of fruits cannot be estimated according to the color of their fruits). Recommendation is to pursue conservation efforts, to improve the knowledge on the seeds germination mastering of the species, to list the species in the Convention on International Trade in Endangered Species (CITES).
