Cloezia deplanchei is an endemic shrub from New Caledonia, growing up to 0,5 to 2 m high. This species is restricted to the south of Grande Terre and it is known from five subpopulations: Col de Plum, route de Prony, La Coulée, Rivière des Pirogues and Dzumac. It is found in shrubland on ultramafic substrate at an altitude range of 30 and 100 m asl. It is grown in areas threatened by bushfires and urbanization. This species is known from 5 localities and its area of occupancy (AOO) is equal to 28 km² for an extent of occurrence (EOO) of 225 km². The combined threats of bushfires and mining activities, allows us to infer a continuous decline of AOO, quality of habitat and number of mature individuals. Using criteria B, Cloezia deplanchei qualifies for Endangered (EN) B1ab(ii,iii,v)+2ab(ii,iii,v).
