Boronia hippopala (velvet boronia) is an aromatic woody shrub that occurs in wet heath/scrub and on their forest margins. It has a restricted distribution with a linear range of about 62 km and is known only from 8 subpopulations in 5 locations in north eastern Tasmania. The total number of mature individuals is estimated at fewer than 15,000. The species is at risk from inappropriate fire regimes and impacts of climate change that may reduce the potential for recruitment from the soil seed store. Predation of seed by insects is an issue for the species and may increase with outbreaks associated with changed environmental conditions. Planning considerations will alleviate potential indirect impacts from adjacent forestry activities and the species will also benefit from proposed forest reserves.

  • ​Flowering of this shrub may occur from September to December. The species can be identified at any time of the year using leaf characteristics though intergradation with Boronia hemichiton can confuse identification.
  • Boronia hippopala grows in wet heaths dominated by species such as Callistemon viridiflorus, species of Melaleuca, Leptospermum and Gahnia grandis, as well as in adjacent Eucalyptus pauciflora–dalrympleana woodland. The underlying substrate is Jurassic dolerite, while drainage is moderate to poor.

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. ​​​​​
