Scientific Name: Atalaya collina

Common Name: Yarwun Whitewood

Conventionally accepted as Atalaya collina (CHAH 2010). Atalaya collina is broadly similar to Atalaya multiflora and there was some doubt as to whether it should be recognised as a distinct species (Barry & Thomas 1994).

Atalaya collina is a small spreading tree growing to 5 m with light grey rough bark. Leaves are compound with one or two pairs of glossy green, discolorous, narrowly elliptic leaflets up to 7 cm long. Flowers are small, cream in colour and up to 8 mm diameter, clustered in dense terminal panicles. The fruit is a single seeded samara (dry winged fruit). (Barry & Thomas 1994; Harden et al. 2006; Reynolds 1991).

This species is known from only two populations in Queensland: west of Gladstone at Yarwun and near Ubobo, west of Miriam Vale (Queensland Herbarium 2008a).

The species has an extent of occurrence of 750 km² (Queensland Herbarium 2008a).

The total area of occupancy is unknown, however it is likely to be restricted as the Yarwun population occurs in an area of approximately 0.25 ha (Barry & Thomas 1994).

The Yarwun population consists of 10 trees of an even age structure, with all plants 3-4 metres tall and no sign of regeneration at the site (Barry & Thomas 1994).

This species' occurs in semi-evergreen vine thicket or 'dry rainforest' which is often highly disturbed. The Yarwun population occurs at a site consisting of a low, isolated clump of Atalaya collina, Atalaya rigida and Atalaya salicifolia. There is no mid-stratum and the ground flora is composed mostly of grasses, Carissa ovata (Currantbush) and a variety of exotic herbaceous weeds (Barry & Thomas 1994, Queensland Herbarium 2008a).
The distribution of this species overlaps with the "Semi-evergreen vine thickets of the Brigalow Belt (North and South) and Nandewar Bioregions" EPBC Act-listed threatened ecological community.

Flowers have been recorded in November and ripe fruits are present in December (Barry & Thomas 1994). The flowers attract a large number of bees (Queensland Herbarium 2008a). The fruit is a winged two-lobed samara (Reynolds 1991).

Threats include the low population size and increased exposure of habitat due to clearing of the surrounding areas, grazing that prevents seedling establishment, possible insect predation of seedlings, and fire impacts (Barry & Thomas 1994).

The following priority recovery and threat abatement actions have been outlined by the Commonwealth Threatened Species Scientific Committee for the recovery of A. collina (TSSC 2008il):

Habitat Loss, Disturbance and Modification

  • Monitor known populations to identify key threats.
  • Monitor the progress of recovery, including the effectiveness of management actions and the need to adapt them if necessary.
  • Minimise adverse impacts from land use at known sites, especially grazing.
  • Investigate formal conservation arrangements, management agreements and covenants on private land, and for crown and private land investigate inclusion in reserve tenure if possible.
  • Manage any other known, potential or emerging threats.


  • Develop and implement a suitable fire management strategy for A. collina.
  • Provide maps of known occurrences to local and state Rural Fire Services and seek inclusion of mitigative measures in bush fire risk management plans, risk register and/or operation maps.

Invasive Weeds

  • Identify and remove weeds in the local area, which could become a threat to A. collina, using appropriate methods.
  • Ensure chemicals or other mechanisms used to eradicate weeds do not have a significant adverse impact on A. collina.

Trampling, Browsing or Grazing

  • Investigate exclusion fencing or other barriers to prevent grazing pressure at known sites.
  • Manage known sites to ensure appropriate grazing regimes occur to allow regeneration from seedlings.

Conservation Information

  • Raise awareness of A. collina within the local community, particularly landholders.

Enable Recovery of Additional Sites and/or Populations

  • Undertake appropriate seed collection and storage.
  • Investigate options for linking, enhancing and establishing additional populations.
  • Implement national translocation protocols if establishing additional populations is considered necessary and feasible.

This list does not necessarily encompass all actions that may be of benefit to A. collina, but highlights those that are considered to be of highest priority at the time of preparing the conservation advice.

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.
