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

Permit: A permit is required under the Tasmanian Threatened Species Protection Act 1995 to 'take' (which includes kill, injure, catch, damage, destroy and collect), keep, trade in or process any specimen or products of a listed species. Additional permits may also be required under other Acts or regulations to take, disturb or interfere with any form of wildlife or its products, (e.g. dens, nests, bones). This may also depend on the tenure of the land and other agreements relating to its management. ​​​​​
