Parsonsia terminaliifolia is an endemic liana of Grande Terre in New Caledonia. This species is known of three disjointed subpopulations (Taom, Négropo). It is found in shrubland on an ultramafic substrate (serpentines) at an altitudinal range 500-700 m asl. On-going and past mining activities impact all subpopulations. Indeed, extraction projections on the coming 25 years will lead to the decline of populations, especially in Ouazangou/Taom (NMC). Population size is unknown. Its extent of occurrence (EOO) and area of occupancy (AOO) are respectivey estimated to be of 318 km² and 16 km² with an estimation of two locations. Parsonsia terminaliifolia is therefore assessed as Endangered (EN) with criteria B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v) with a continuing decline of all concerned criteria.

Geographical area


Parsonsia terminaliifolia is an endemic liana of Grande Terre in New Caledonia. This species is known of three disjointed subpopulations (Taom, Koniambo, Négropo).

Population


Population size is unknown.

Habitat


It is found in shrubland on an ultramafic substrate (serpentines) at an altitudinal range 500-700 m asl.

Threats


On-going and past mining activities impact all subpopulations. Indeed, extraction projections on the coming 25 years will lead to the decline of populations, especially in Ouazangou/Taom (NMC).

Conservation


Parsonsia terminaliifolia is not protected by legislation. It does not occur in any protected area. This species would benefit from ex-situ and in-situ emergency conservation actions. It is proposed to ensure the follow-up of known sub-populations, to preserve a viable population on delimited perimeters on each mining areas.
