Indicative distribution
The areas shown in pink and/purple are the sub-regions where the species or community is known or predicted to occur. They may not occur thoughout the sub-region but may be restricted to certain areas.

Description
The Mauve Burr-daisy is a sprawling, branched herb that grows to 20 cm tall and up to 1 m wide. The soft, bright green, hairy leaves have indented edges. They are up to 3 cm long and 9 mm wide. The 2 cm wide flower-heads are solitary, mauve, and have a yellow centre. Flowers may also be white, blue or pink. They appear in spring and summer. Flowers are followed by a head of brown burrs that may stick to clothing and animals' coats.
Distribution
The distribution of the Mauve Burr-daisy is centred on the Monaro and Kosciuszko regions. There are three known sites in the upper Shoalhaven catchment. There are old and possibly dubious records from near Oberon, the Dubbo area and Mt Imlay.
Habitat and ecology
- Found in montane and subalpine grasslands in the Australian Alps.
- Found in subalpine grassland (dominated by Poa spp.), and montane or natural temperate grassland dominated by Kangaroo Grass (Themeda australis) and Snow Gum (Eucalyptus pauciflora) Woodlands on the Monaro and Shoalhaven area.
- Appears to be a coloniser of bare patches, which explains why it often occurs on roadsides.
- Apparently common on roadsides in parts of the Monaro, though it does not persist for long in such sites.
- Does not persist in heavily-grazed pastures of the Monaro or the Shoalhaven area.
- Dispersed by animals which carry the sticky burrs to new sites.
Regional distribution and habitat

Threats
- Loss and degradation of habitat and/or populations from road works (particularly widening or rerouting).
- Loss and degradation of habitat and/or populations by clearing of habitat for residential and agricultural developments.
- Loss and degradation of habitat and/or populations by intensification of grazing regimes.
- Loss and degradation of habitat and/or populations by invasion of weeds.
- Loss and degradation of local habitat and/or populations in Kosciuszko National Park by horses and roadworks.
- Potential encrochment and competition from Kunzea ericoides and Kunzea parvifolia.
- Pigs digging up individuals.
- Grazing by cattle and sheep is a threat to plants while the plants are actively growing, flowering or in fruit.
Recovery strategies
Priority actions are the specific, practical things that must be done to recover a threatened species, population or ecological
community. The Office of Environment and Heritage has identified
9 priority actions
to help recover the Mauve Burr-daisy in New South Wales.
Activities to assist this species
- Undertake pig control in areas that surround populations.
- Protect known populations from changes to land use.
- Do not undertake road works, pasture modification or other changes in land use that may affect populations.
- Do not increase grazing pressures on sites where populations persist - reduce grazing pressures where possible.
- Undertake weed control in and adjacent to populations, taking care to spray or dig out only target weeds.
- Mark sites and potential habitat onto maps (of the farm, shire, region, etc) used for planning (e.g. road works, residential and infrastructure developments, remnant protection, rehabilitation).
- Search for new populations in potential habitat.
