Scientific name: Allocasuarina luehmannii Woodland in the Riverina and Murray-Darling Depression Bioregions

Commonwealth status: Not listed

Allocasuarina luehmannii Woodland in the Riverina and Murray-Darling Depression bioregions is the name given to the ecological community dominated by Buloke (Allocasuarina luehmannii), sometimes with co-occurring tree species. The community typically comprises an open tree canopy with a sparse and highly variable ground layer dominated by grasses and herbs, sometimes with scattered shrubs and/or small trees. The structure and species composition of the community varies depending on disturbance history and temporal variability in rainfall. The species composition of a site will be influenced by the size of the site, recent rainfall or drought conditions and by its disturbance (including grazing, land clearing and fire) history. The number and relative abundance of species will change with time since fire, and may also change in response to changes in fire frequency or grazing regime. The groundcover is highly variable in structure and composition. It is typically sparse, but may be more continuous within patches or following substantial rainfall events.

Allocasuarina luehmannii Woodland shares a number of species with another endangered ecological community listed under the Threatened Species Conservation Act 1995: Sandhill Pine Woodland in the Riverina, Murray-Darling Depression and NSW South Western Slopes bioregions. These two ecological communities inhabit similar soils and landforms and have similar geographic distributions. They may be distinguished on the basis of the relative abundance of their tree species and subtle differences in composition of their understorey. When tree abundance is assessed at hectare scales, A. luehmannii is the most abundant tree species in Allocasuarina luehmannii Woodland, whereas Callitris glaucophylla is the most abundant tree species in Sandhill Pine Woodland.


Allocasuarina luehmannii Woodland has been recorded in the southern part of the Riverina bioregion from near Urana and Mulwala in the east to the Barham district, and may extend as far west as Euston in the southern part of the Murray-Darling Depression bioregion. The community occurs in small patches within this range and is currently estimated to cover less than 500-1500ha. Approximately 6 ha of Allocasuarina luehmannii Woodland are estimated to occur within Lake Urana and Wiesners Swamp Nature Reserves. The remainder of the community occurs on private land or on public easements.

Habitat and ecology

  • Allocasuarina luehmannii Woodland typically occupies patches of red-brown loamy sands with alkaline sub-soils on the alluvial plain of the Murray River and its tributaries in south-western NSW.
