This species occurs in maquis on ultramafic rocky ridges at an altitude range of 5 to 1,100 m asl. Its habitat is impacted by recurrent bushfires and mining activities at Koniambo, Tiébaghi and Kaala massifs. Its Area of Occupancy (AOO) and Extent of Occurrence (EOO) being respectively estimated to be 140 and 2,981 km², Phyllanthus buxoides is considered Near Threatened (NT) close to VU B1ab(i,ii,iii,v)+2ab(i,ii,iii,v) with an estimated decline of all the concerned subcriteria and a number of locations above 10.
