Pandanus sphaerocephalus is an endemic shrub restricted to the south of Grande Terre in New Caledonia. This species is found in dense humid forest on ultramafic rocks at an altitude range 700-1,200 m asl. Main identified threat is linked to habitat damage by ongoing uncontrolled bushfires. Its extent of occurrence (EOO) and area of occupancy (AOO) are respectively estimated to 267 km² and 24 km² while the number of locations are estimated to be six. P. sphaerocephalus is therefore assessed as Vulnerable (VU) with criteria B1ab(iii,v)+2ab(iii,v) with a continuing decline of of its habitat quality and number of mature individuals.
