It is found in dense humid forest on ultramafic substrate at an altitudinal range 100-700 m asl. The main impact identified comes from ongoing mining activites and bushfires. Its area of occupancy (AOO) and extent of occurrence (EOO) being respectively estimated to 36 and 972 km² while the number of locations is estimated to be seven, Pycnandra deplanchei subsp. floribunda is considered Vulnerable (VU) with criteria B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v) with a continuing decline of all concerned sub-criteria.
