Austrocynoglossum latifolium is a trailing perennial herb in the Boraginaceae family. It occurs in New South Wales, Queensland, South Australia, Victoria and Tasmania. Within Tasmania, the species is known from four widely-separated locations in the State's north, including King Island. Its recorded habitat in Tasmania includes damp eucalypt forest along creeklines and rivers, and Melaleuca ericifolia swamp forest. The greatest threat to the species in Tasmania is inundation of plants and habitat due to dam construction. Other threats include land clearance, hydrological changes, weed invasion, stock grazing and trampling, and chance catastrophic events near known localities.
- 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.
- ‘Habitat’ refers to both known habitat for the species (i.e. in or near habitat where the species has been recorded) and potential habitat (i.e. areas of habitat with appropriate characteristics for the species and within the species' potential range which have not yet been adequately surveyed).
- If in doubt about whether a site represents potential habitat for this species, contact the Threatened Species Section for further advice.
- The known range of forest houndstongue includes four widely-separated locations in the State's north including King Island (see distribution map, above). The potential range for forest houndstongue includes King Island and northern and north-eastern Tasmania.
- Habitat for forest houndstongue corresponds to 'Riparian Bush' and 'Tea-tree and paperbark wet scrub and forest’ in the DPIPWE Bushcare Toolkit.
- Habitat for forest houndstongue includes the following elements: damp eucalypt forest along creeklines and rivers, and Melaleuca ericifolia swamp forest; variable geology including Precambrian quartzitic sequences, Permian sediments, Jurassic dolerite, Devonian granite and Quaternary alluvium on a range of substrates; the altitude range is 5 to 140 m above sea level.
What to avoid
The main threats to forest houndstongue are any activities which clear or degrade habitat, including:
Clearing vegetation, including cutting and slashing
Inundation of a site (through dam construction)
Unrestricted stock grazing
Invasion of a site by woody weeds
- This perennial herb flowers in spring to summer. Non-specialists may be able to detect forest houndstongue at any time of year due to its distinctive rough-textured foliage. See the Listing Statement for more information on how to identify this species.
- Surveying for forest houndstongue will only require a permit if part of the plant is destroyed or damaged, for example for identification.
Cutting or clearing trees or vegetation
- To avoid loss of the species at known localities – do not remove vegetation in this species’ habitat, including clearing, cutting and slashing.
- To avoid permanent habitat loss - do not convert habitat (e.g. to plantation, pasture or cropping land).
- To avoid total loss of known localities – do not inundate known localities through dam construction.
Changing water flow / quality
Use of chemicals
- To protect known localities of forest houndstongue – avoid risk of off-target herbicide damage to plants during the treatment of weeds within or adjacent to known localities.
