Santalum austrocaledonicum var. pilosulum is a variety of sandal (small tree of 2-10m) endemic to the vicinity of Nouméa in New Caledonia. It is found in dry forest and degraded vegetation at low altitude (10-400 m asl). The main threat comes from the degradation of forest habitat caused by urbanization (forest clearing), bushfires and invasive species. Its extent of occurrence (EOO) and area of occupancy (AOO) are respectively 225 km² and 36 km² while the number of locations is estimated to be 4. Santalum austrocaledonicum var. pilosulum is therefore considered Endangered (EN) according to criteria B1ab(iii)+2ab(iii) with a continuing decline of habitat quality.
