Current name: Ozothamnus eriocephalus

Synonym: Helichrysum eriocephalum

Ozothamnus eriocephalus, is a weakly woody shrub to 0.6 m high, with fine white hairs forming a mat over the branches. Leaves are lance shaped and both surfaces are covered in a web of fine white hairs. Floral heads form dense sub-hemispherical corymbs with a dense webbing of fine hairs. Floral heads consist of about 40 bisexual florets, and are white to mauve or bluish (Burbidge 1958; Queensland Herbarium 2009).

Ozothamnus eriocephalus is restricted to the east-central area of Queensland, between Bowen and Mackay (Queensland Herbarium 2009), with an extent of occurrence of approximately 15 000 km² (Queensland Herbarium 2009). There are 14 collection records that consist of nine locations (Queensland Herbarium 2009). Locations include Mount Abbott (private land), Gloucester Island (Dryander NP), the Lake Elphinstone area (one collection in 1870), Clarke Range (Eungella NP) and near Sydney Heads (Denham Range, Homevale NP) (Bean 1994b; Pollock 2001 pers. comm.; Queensland Herbarium 2009).

Specimen labels note Ozothamnus eriocephalus as "common", "occasional" and "only one plant seen" at collection sites (Queensland Herbarium 2009).

Ozothamnus eriocephalus occurs in Homevale NP, Eungella NP and Gloucester NP (Queensland Herbarium 2009).

This species is known from a range of habitat types, including the margins of disturbed notophyll vine forest, margins of gallery forest, microphyll vine forest, tall open New England Blackbutt (Eucalyptus andrewsii) - E. resinifera forest with an understorey of Allocasuarina littoralis, in open eucalypt forest and on rocky ridges with Eucalyptus spp. - Acacia spp. scrub (Bean 1994; Queensland Herbarium 2009). It is also known from the edge of creek banks and in crevices on steep granite slopes, often in sunny situations. It is known from moderate to high elevations ranging from 380–950 m. It occurs on skeletal, sandy or gravelly soils or occasionally deeper red-brown clay loams derived from granites and sandstones (BRI collection records; Bean 1992b, 1994b; Pollock 1997).

Flowering occurs in March to September and fruiting is recorded in March and July (Queensland Herbarium 2009).

Ozothamnus eriocephalus is not a very distinct species; therefore, surveys should be conducted during the flowering period (Bean 2009a), when they are most readily identified.

Potential threats to Ozothamnus eriocephalus include inappropriate fire regimes, inappropriate grazing regimes and degradation of habitat by weeds. Threatening weed species include Lantana (Lantana camara), Molasses Grass (Melinis minutiflora), Guinea Grass (Panicum maximum) and Billygoat Weed (Ageratum conyzoides) (Pollock 1997). Timber harvesting is no longer a threat, as timber areas are now conserved in national parks (Bean 2009a).

A draft Species Management Profile has been developed by the Queensland Government for the amelioration of impacts during forest operations that may impact Ozothamnus eriocephalus (Pollock 1997). Protective measures include (Pollock 1997):

  • Where O. eriocephalus occurs, establish a protective buffer which excludes clearing. Minimum buffer area is to be 2500 m² (0.25 ha). All O. eriocephalus plants should be at least 25 m inside the buffer boundary.
  • Where practical, control weeds such as Lantana (Lantana camara), Guinea Grass (Panicum maximum), Molasses Grass (Melinis minutiflora), Cobblers Peg (Bidens pilosa) or Blue-top (Ageratum conyzoides) on sites where O. eriocephalus occurs.
  • Monitor the impact of grazing and adjust grazing management to ameliorate adverse impacts.
  • Minimise the risk of a hot wildfire on sites where O. eriocephalus occurs, and until the optimum fire regimes are determined, continue to carry out prescribed burns, provided hot fires are avoided.

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
