DistributionRead full entry
Range DescriptionThe distribution of this species, an Australian endemic, is extremely restricted and is confined to nine small (up to 54ha) unconnected patches of rainforest (totalling about 200ha) above 500m asl at Kroombit Tops, south-west of Gladstone (Clarke et al. 1999; J. Clarke pers. comm.). It is believed to be a relict species, restricted to Kroombit Tops through habitat fragmentation that disrupted rainforest connections between south and north-east Queensland (Czechura 1986a). Within the rainforest patches, populations are clumped around drainage lines and seepage areas (J. Clarke pers. comm.). The extent of occurrence is estimated to be 18km and the area of occupancy is estimated to be 60ha (J. Clarke pers. comm). Surveys in February 1997 and regular surveys since 1998 have greatly expanded the known distribution of the species (Clarke et al. 1999; J. Clarke pers. comm.). All potential sites on the Kroombit Tableland and escarpment have been searched at least once during the calling season although additional potential habitat for the species exists on the Dawes Range and Mount Roberts (M. Cunningham pers. comm.). To date, surveys of suitable habitat on the Dawes Range and Mount Roberts have failed to find this species (E. Meyer pers. comm.).
