Burretiokentia koghiensis is a solitary, subcanopy, palm tree, endemic of New Caledonia, restricted in the Mont Koghi massif in the southwest of Grande Terre. B.koghiensis occurs in rain forest in a very rocky habitats on soils derived from serpentine from 500-600 m. The population is estimated to close to 250 mature individuals and is located near the area where tourist activities are set up. Thus this population is very impacted by the development of tourist activities and seed collections as the area is regularly frequented by tourists and local population. With an area of occupancy (AOO) and extent of occurrence (EOO) being both estimated to 4 km², B.koghiensis is considered Critically Endangered (CR) using criteria B1ab(iii,v)+2ab(iii,v) with an estimation of one location and a decline of habitat quality and number of individuals.
Geographical area
Burretiokentia koghiensis is an endemic palm tree of New Caledonia, restricted in the Mont Koghi massif in the southwest of Grande Terre.
Population
The population is estimated to be around 250 mature individuals in a single population.
Habitat
B. koghiensis occurs in rain forest in a very rocky habitats on soils derived from serpentine from 500-600 m.
Threats
This species is highly threatened as the area where tourist activities take place is located near the population of B.koghiensis. The main threats identified are land clearing due to the developement of tourist activities, seed collections and impacts of invasive species (rats, rusa deer (Rusa timorensis) and pigs).
Conservation
Burretiokentia Koghiensis is protected by legislation in Province Nord and Province Sud. Prospection in Vallée de la Thy is recommended. This species would benefit from ex-situ and in-situ emergency conservation actions as well as invasive species control.
