endemique
UICN

Red List Status -

Endangered (EN) , assessed in 05/04/2018

Bocquillonia aff. Brachypoda is an endemic shrub of New Caledonia restricted in the north west of Grande Terre, from Poya to Pouembout. It is found in dry forest and shrubland on volcano-sedimentary and ultramafic substrate, from 300 and 1,100 m asl. The main threats identified are urbanisation, Rusa deer (Rusa timorensis), feral pigs (Sus scrofa) and uncontrolled bushfires. Known from five locations, its area of occupancy (AOO) and extent of occurrence (EOO) are 44 and 295 km², respectively. Therefore, Bocquillonia aff. Brachypoda is considered Endangered (EN) B1ab(ii,iii,v)+2ab(ii,iii,v) with an estimated decline of AOO, habitat quality and number of mature individuals.

Geographical area


B. aff. Sessiliflora is endemic to New Caledonia where it is restricted in the north west of Grande Terre, from Poya to Pouembout.

Population


Population size is unknown.

Habitat


B. aff. Sessiliflora occurs in dry forest and shrubland on volcano-sedimentary and ultramafic substrate, from 30 and 1,100 m asl.

Threats


The main threats identified are bushfires, urbanisation (land clearing) and invasive species (Rusa deer (Rusa timorensis) and feral pigs (Sus scrofa)).

Conservation


B. aff. Brachypoda is not protected by legislation in New Caledonia and it does not occur in any protected area. This species is taxonomically clear and its description is needed. Ex situ and in situ emergency conservation actions and also awarness amongs the local population is also recommended. It is proposed to ensure the follow-up of the only known subpopulation and to preserve a viable population on delimited perimeters. It is also recommended to inform the DSCGR (emergency services), responsible for the coordination of the firefighting effort, on the presence of the species in the concerned area. Plus prospections in the north west are needed are needed to confirm the presence of the species and to better estimated its population.
