Abstract
Philotheca sporadica (Kogan Waxflower) is an endangered species occurring within the distribution of a more widespread congener, P. difformis ssp. difformis, a common understorey shrub of the cypress-dominated woodlands of western Queensland. It is an edaphic specialist and is most often found growing in close association with duricrust formations in the Kogan-Dalby area. Approximately 10ha. of habitat occupied by the species will be impacted due to the construction of coal seam gas collection infrastructure, and a number of proposed offset sites to compensate for this loss have been stipulated by government authorities. The aim of this study was to provide relevant ecological and population genetic information for P. sporadica to facilitate the effective management of the required translocations.
