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.
- Important: Is this species in your area? Do you need a permit? Ensure you’ve covered all the issues by checking the Planning Ahead page.
- Important: Different threatened species may have different requirements. For any activity you are considering, read the Activity Advice pages for background information and important advice about managing around the needs of multiple threatened species.
- 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.
