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 Red Box (Eucalyptus polyanthemos), River Red Gum (Eucalyptus camaldulensis), Grey Box (Eucalyptus microcarpa) and Black Box (Eucalyptus largiflorens) if you have space. Smaller trees like Snow-in-Summer (Melaleuca linariifolia) and River She-oak (Casuarina cunninghamiana) 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 wattles like Grey Mulga (Acacia brachybotrya) and Deane's Wattle (Acacia deanei) that burst into flower in winter and spring. To create habitat, consider installation of nestboxes for native birds and creating tree hollows in old, dead tree limbs.


Plant native shrubs such as dazzling endemic Proteaceae species like the Rusty Spiderflower (Grevillea floribunda), Silver Banksia (Banksia marginata) and Tumut Grevillea (Grevillea wilkinsonii). Native peas such as beautiful Austral Indigo (Indigofera australis), Common Eutaxia (Eutaxia microphylla) and Small-leaved Bush-pea (Pultenaea foliolosa) along with other shrubs like Leptospermum scoparium and Native Blackthorn (Bursaria spinosa) are fabulous plants for creating 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 the classic Paper Daisy (Xerochrysum bracteatum), Clustered Everlasting (Chrysocephalum semipapposum) and Woolly-buttons (Leiocarpa panaetiodes). Other ground-layer plants like Long-leaved Flax-lily (Dianella longifolia), gorgeous Native Sarsaparilla (Hardenbergia violacea), Blue Pincushion (Brunonia australis) and Pepper-leaved Senna (Senna barclayana) are great for a variety of forms. Also consider tufts of native grasses to bring back grassland specialists. Weeping Rice-grass (Microlaena stipoides), Kangaroo Grass (Themeda triandra), Common Wheat-grass (Elymus scaber) and Elegant Spear-grass (Austrostipa elegantissima) are great choices. To create habitat, consider installing a pond or bog-garden with native aquatic and riparian plants, log-piles for sheltering amphibians and reptiles and leave areas of leaf-litter for important insects.


Comprised of a large expanse of dry hills and valleys, this ecoregion covers important agricultural areas like the Riverina region and the Murray-Darling basin. Agriculture has dramatically altered much of this land and its waterways. The area has a semi-arid climate and is dominated by open woodlands, scrubs and grasslands. Large Coolibah, Poplar Box and River Red Gums are a frequent character sight. Much of the wildlife here has had to adapt to the dramatic changes caused by humans, and while some species have managed this, many have become increasingly rare and threatened. Birds like the Plains-wanderer and highly-elusive marsupials like quolls and rock-wallabies are now a very rare sight.

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.

(Pseudomys pilligaensis)

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.

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

Kangaroos are important ecosystem engineers keeping grasslands in balance. In highly diverse box grassy woodlands, kangaroos and wallabies are vital in maintaining high species richness of native wildflowers and thus, their insect pollinators.

Life-support Systems​

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