Basselinia gracilis is an endemic diminutive palm tree restricted to a relatively small sector of the north-eastern part of Grande Terre in New Caledonia: in the south of col d'Amos (between the peaks of Salandané and Mandjelia) and Mont Tio. It is found in humid forest at high altitude (500-1,000 m asl.) on soils derived from schist rock. Main identified threats are linked to seeds destruction by rats and habitat damage by wild pigs. It has an area of occupancy (AOO) and extent of occurrence (EOO) respectively equal to 20 and 27 km² with two locations. Basselinia gracilis is considered Endangered (EN) B1ab (iii,v)+2ab(iii,v) with a decline of habitat quality and number of mature individuals.

Geographical area


Basselinia gracilis is an endemic palm tree restricted to a relatively small sector of the north-eastern part of Grande Terre in New Caledonia, from Mandjelia to Mt Tio

Population


Population size is unknown, it is only found in two locations with a small number of individuals.

Habitat


It is found in humid forest at mid altitude from 500-1,000 m asl. on soils derived from schistose rock.

Threats


Main identified threats are linked to seeds destruction by rats and habitat damage by wild pigs.

Conservation


Basselinia gracilis is protected by lesgislation in province Nord and it does not occur in any protected area. This species would benefit from ex-situ and in-situ emergency conservation actions although it is cultivated in ex situ at Lavoix's garden in Nouméa. Prospection in Mandjelia to Ignambi areas are needed to better evaluate the conservation status of this species. Plateau de Dogny seems to be another location to be surveyed to check on the species. Furthermore herbarium specimens of Basselinia gracilis in Nouméa need to be rechecked in comparison with Basselinia eriostachys.
