Boronia gunnii (river boronia) is an aromatic woody shrub that occurs in rocky riparian habitats along limited sections of the St Pauls, Dukes and Apsley rivers in eastern Tasmania, with historic records from near Launceston. The extant distribution of the species is restricted and localised, with a linear range of about 17 km, occupying 3 to 5 ha, and the total number of mature individuals is estimated to be fewer than 1,000. This makes the species susceptible to inadvertent or chance events and changed environmental conditions. Threats include inappropriate hydrological regimes, inappropriate management of the riparian zone, including areas upstream of known sites, and an increase in the frequency of fires
