Scientific name: Eucalyptus beardiana

Common name: Beard's Mallee

Beard's Mallee is a mallee growing to 5 m tall, with smooth, pinkish-grey to cream bark. The leaves are narrow, a light greyish-green and grow up to 12.5 cm long and 1.5 cm wide. The inflorescences are axillary and have up to 11 flowers. The peduncle is 3 cm long, terete and recurved. The buds are up to 2.1 cm long and 6 mm wide, they are cup-shaped with a beaked cap. The flowers are creamy white, with the lower half of the stamens united. The fruit are pedicellate, hemispherical and flaring at the top. The valves are protruding and number 4–5 (Brooker & Blaxell 1978; Brown et al. 1998).

Beard's Mallee is endemic to Western Australia and is known from 23 locations in the Northhampton, Shark Bay and Mullewa areas (WA DEC 2009a). The extent of occurrence is estimated to be approximately 8300 km2. There are insufficient data to calculate the area of occupancy (WA DEC 2009a).

The Beard's Mallee population is naturally fragmented, as it occurs within discontinuous habitat and some populations are widely separated with considerable distances between them (WA DEC 2009a). The following table lists subpopulation information for the species:

The following is a summary of the historical records and collection of Beard's Mallee (WA DEC 2009a):

  • first collected in 1975 on Hamelin and Coburn pastoral stations, approximately 60 km north-east of Kalbarri
  • four subpopulations found at Nerren Nerren, Eurardy and Nanga Stations in 1986–1988
  • five subpopulations found on Nerren Nerren and Eurardy pastoral stations in 1995–1997
  • collected from Toolonga Nature Reserve (NR) in 1996
  • ten plants found on private property 8 km north-west of Mullewa in 1999, further surveys in 2003 found 43 plants in the subpopulation
  • collected from nine new locations in Kalbarri National Park (NP) between 2003–2007.

The estimated total population for Beard's Mallee is 1378 plants in 23 subpopulations (WA DEC 2009a).

Beard's Mallee generally occurs on red or yellow, flat or undulating sandplain and sand ridges (Brown et al. 1998; Kelly et al. 1995). It grows in mallee/tree heath or tall open shrubland/woodland with Yuna Mallee (Eucalyptus jucunda), Mallalie (E. eudesmioides), E. gittinsii, Sceptre Banksia (Banksia sceptrum), Ashby's Banksia (B. ashbyi), Broom Honey-myrtle (Melaleuca uncinata), Acacia spp., Grevillea spp. and Persoonia spp. (Kelly et al. 1995; Brown et al. 1998; Patrick 2001).

A site north-west of Coburn Homestead occurs on low, red, sand dunes. Associated species include Eucalyptus roycei, Banksia ashbyi, Hakea stenophylla, Acacia longispina and Plectrachne danthonioides (Brooker & Blaxell 1978).

A site south of Wannoo occurs in tall open-shrubland on yellow sand with occasional sand ridges. Associated species include Actinostrobus arenarius, Banksia sceptrum and Sandplain Woody Pear (Xylomelum angustifolium) (Brooker & Blaxell 1978).

Beard's Mallee is recorded flowering in August–September (Brown et al. 1998).

Beard's Mallee is distinguished by its broader leaves, larger buds and larger fruit with sunken disc (though still broad and prominent) (Brooker & Blaxell 1978; Brown et al. 1998). Surveys should be conducted in August–September, when fruit and buds are common (Brown et al. 1998).

Known threats to Beard's Mallee include firebreak and track maintenance, grazing and weeds. Maintenance activities, including grading, chemical spraying and the mowing of roadside vegetation are a threat to ten of the 23 subpopulations. Livestock have degraded one subpopulation, resulting in weed invasion (Kelly et al. 1995; WA DEC 2009a).

The main potential threat to Beard's Mallee is livestock and feral Goat (Capra hircus) grazing, which could impact 12 subpopulations (WA DEC 2009a).

Refer to the Commonwealth Conservation Advice (TSSC 2010aft) for information on research priorities and recovery priority actions to mitigate threats including habitat loss, disturbance and modification, trampling, weeds and fire. Raising awareness of the species and enabling recovery of additional populations are also encouraged in the Advice.

Management documents relevant to Beard's Mallee include:

  • Declared Rare and Poorly Known Flora in the Geraldton District (Patrick 2001)
  • Commonwealth Conservation Advice on Eucalyptus beardiana (TSSC 2008aft).

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.
