Eucalypt Woodlands of the Western Australian Wheatbelt

The Eucalypt Woodlands of the Western Australian Wheatbelt ecological community is endemic to the wheatbelt region of southwestern Western Australia, located inland between the Darling Range and the Goldfields region. It occurs within the IBRA[1] subregions of Merredin (Avon Wheatbelt 01), Katanning (Avon Wheatbelt 02) and Western Mallee (Mallee 02) plus the drier eastern to south-eastern parts of the Jarrah Forest bioregion that lie adjacent to the Avon Wheatbelt bioregion and receive less than 600 mm mean annual rainfall.

The ecological community generally occupies the flatter, lower elevation landscapes of the wheatbelt region such as plains, valley floors, watercourses/wetlands including the margins of salt lakes, and extends onto breakaways and gravel rises.

The ecological community is a type of woodland, where the trees are usually well spaced and the canopy crown cover is at least 10%. The tree canopy is dominated to co-dominated by one or more of several key species of Eucalyptus listed in Table 1. The eucalypts share a tree or mallet form, i.e.  they typically have an erect, single-stemmed trunk with a variable crown shape. The woodland represents a complex mosaic in which the key eucalypt species may co-occur in various combinations.

The understorey is highly variable in its structure and composition, ranging from almost bare to grassy, herb-rich, shrubby or thicket forms.

The ecological community supports a diverse range of fauna, including black cockatoos, the numbat, malleefowl and chuditch, amongst other species, providing essential resources such as shelter and food for the animals.



Table 1.  Key eucalypt species that occur in the tree canopy of the Eucalypt Woodlands of the Western Australian Wheatbelt ecological community. Within a given patch of the ecological community, one or more of these species are dominant or co-dominant. Scientific are current as at October 2015.
