Eastern Australia mulga shrublands


Flat plains and low hills in the central-west of Queensland and New South Wales. This region is rich in plant-life that has evolved to survive on relatively poor, old soils, and often with little rain. Large bodies of water such as those associated with the Paroo and Bulloo Rivers attract native fauna of all shapes and sizes.

Help your Ecoregion
So what can you do to help your ecoregion? Below is a list to help you support your ecoregion, while also achieving life's everyday tasks. Don’t underestimate your power in doing good for nature!

At Home
Below is a list of actions you can easily take at home to minimise your impact on the ecoregion in which you live, and the rest of the planet too!
In your Garden
Below is a list of native plants and habitat creation tips you can use in your garden or on your property to give your ecoregion and its species a boost!


Plant large feature trees common across the region such as River Red Gum (Eucalyptus camaldulensis), Silver-leaved Ironbark (Eucalyptus melanophloia), Poplar Box (Eucalyptus populnea) and Western Bloodwood (Eucalyptus terminalis) if you have space. Smaller trees like Leopardwood (Flindersia maculosa) and White Cypress-pine (Callitris glaucophylla) are more suitable for smaller gardens. To create habitat, consider installation of nestboxes for native birds and creating hollows in old, dead tree limbs.


Plant native sub-canopy trees like Boonaree (Alectryon oleifolius), False Sandalwood (Eremophila mitchellii), Umbrella Wattle (Acacia ligulata) and Doodlallie (Acacia excelsa). To create habitat, consider installation of nestboxes for native birds and creating tree hollows in old, dead tree limbs..


Plant native shrubs such as the good food-source Tangled Lignum (Duma florulenta), Bignonia Emu-bush (Eremophila bignoniiflora) and the beautiful, succulent Pearl Bluebush (Maireana sedifolia). These plants create dense shrubby refugia and provide plenty of nectar for birds and mammals. To create habitat, consider installing insect hotels, compost-heaps and bird-baths in this layer.


Plant colourful native daisies like Drumsticks (Pycnosorus globosus), Chamomile Sunray (Rhodanthe anthemoides), Piliga Daisy (Brachyscome formosa) and Cut-leaved Daisy (Brachyscome multifida). Other ground-layer plants like Shiny Pansy (Goodenia glabra), gorgeous Creeping Monkey-flower (Elacholoma prostrata) and quirky-looking Nardoo (Marsilea drummondii), as well as small shrubby plants like Dodonaea petiolaris and Prostanthera suborbicularis, are great for a variety of forms. To create habitat, consider installing a pond or bog-garden with native aquatic and riparian plants such as Cane-grass Bamboo (Eragrostis australasica), log-piles for sheltering amphibians and reptiles and leave areas of leaf-litter for important insects.


A large, dry area of open plains and low hills. The geology of the Eastern Australia mulga shrublands is very old and stable with poor soils and a network of ancient river systems often forming lakes and billabongs in wetter periods. The area is dominated by the Mulga; a species of dome-shaped acacia (or wattle) that thrives in the region’s pool, sandstone or claystone soils. The plant is so common that it is regarded as a keystone species creating swathes of plant communities that form characteristic habitats for some of the Mulga Lands’ most iconic wildlife. From bilbies to parrots and sleek snakes to bounding Western Grey Kangaroos, this region contains some of the richest protected areas in Queensland and New South Wales, many of which also look after significant heritage of Indigenous Peoples.

Ecoregion Structure
The structure of the ecoregion is defined as the key living and non-living features characterising its ecosystems, and the differences between how these ecosystems are arranged. For example, layers of vegetation, geology, habitat features and landscapes.

Ecoregion Composition
The composition of the ecoregion is defined as the biodiversity that inhabits its ecosystems, and the differences between this biodiversity. For example, communities, populations, species, subspecies and genetic traits.
Keystone Species​
Keystone species are those that have a disproportionately large effect on the ecosystems in which they live, relative to their natural abundance there. In other words, species with a really important role in the health of ecosystems.
Flagship Species
Flagship species are those that are chosen by people to represent a wider conservation message, usually for a given place or social context, and as such often carry conservation messages for wider biodiversity.

(Calandrinia balonensis)

Recently Extinct Species
All around the world, biodiversity is declining at a concerning rate. For some species it's already too late, and they have disappeared from the ecoregions they once called home. These are some examples of those lost species.

(Rhipidura cervina)

Ecoregion Function
The function of the ecoregion is defined as how its structural and compositional components all work together to form ecological relationships and processes which change over time through geological shifts and evolution by natural selection.

Keystone Relationships

Mulga Mistletoe, and many other species of mistletoes are incredibly important sources of food for animals. In the otherwise harsh landscape of the mulga lands, clumps of mistletoe act as advertisements to nectar, fruit and invertebrate prey.

Life-support Systems​

Biodiversity is fundamental to a healthy planet and thriving communities, but the world's species are under tremendous threat.
