Bocquillonia grandidens is an endemic shrub of New Caledonia distributed from Païta in the south to Vallée Néavin in the center of Grande Terre. It is found in dense humid forest on mixed substrates made of volcano-sedimentary, ultramafic substrate and flyschs, from 100 and 500 m asl. The main threats identified are Rusa deer (Rusa tumorensis) and uncontrolled bushfires. Known from nine locations, its area of occupancy (AOO) and extent of occurrence (EOO) are 52 and 4,167 km², respectively. Therefore, B. grandidens is considered Vulnerable VU B1ab(iii,v)+2ab(iii,v) with an estimated decline of habitat quality and number of mature individuals.
