Vulnerable (VU) , assessed in 05/04/2018

Bocquillonia aff. Sessiliflora is an endemic shrub of New Caledonia. It has a discontinuous distribution between the north west and Grand Nouméa in the south of Grande Terre. It is found in dry forest and shrubland on volcano-sedimentary and ultramafic substrate, from 10 and 100 m asl. The main threats identified are urbanisation, Rusa deer (Rusa timorensis) and uncontrolled bushfires. Its area of occupancy (AOO) and extent of occurrence (EOO) are 44 and 3,718 km², respectively, while its number of locations is equal to nine. Therefore, Bocquillonia aff. Sessiliflora is considered Vulnerable (VU) B1ab(ii,iii,v)+2ab(ii,iii,v) with an estimated decline of AOO, habitat quality and number of mature individuals.
