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!

CANOPY LAYER

Plant large feature trees like the stunning Salmon Gum (Eucalyptus salmonophloia), Gimlet (Eucalyptus salubris), Lemon-flowered Gum (Eucalyptus woodwardii) and Coolgardie Gum (Eucalyptus torquata) if you have space. To create habitat, consider installation of nestboxes for native birds and creating hollows in old, dead tree limbs.

SUB-CANOPY LAYER

Plant native sub-canopy trees like the mallee-forming Merrit (Eucalyptus urna), Griffith's Grey Gum (Eucalyptus griffithsii), Brookleaf Mallee (Eucalyptus kruseana) and Daarwet (Eucalyptus loxophleba). To create habitat, consider installation of nestboxes for native birds and creating tree hollows in old, dead tree limbs.

SHRUB LAYER

Plant native shrubs like the lovely, dense Allocasuarina campestris, Boree (Melaleuca pauperiflora), Wax Grevillea (Grevillea insignis), Jam Wattle (Acacia acuminata), Desert Hop-bush (Dodonaea stenozyga), the prickly Isopogon gardneri and the lovely Fox Banksia (Banksia sphaerocarpa). These species are great 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.

GROUND LAYER

Plant colourful natives like the Pimelea Daisy-bush (Olearia pimeleoides), Goldfields Daisy (Olearia muelleri), Tall Mulla Mulla (Ptilotus exaltatus), Flannel Bush (Solanum lasiophyllum), Orange Immortelle (Waitzia acuminata), Schoenia (Schoenia cassiniana) and Pink Velleia (Velleia rosea). 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.

A highly diverse ecoregion bursting with beauty. This ecoregion is renowned for being a hotspot for mallee woodlands and scrub, with many endemic plant species, especially gum trees with over 170 species recorded. The vegetation is generally open, with larger woodlands in the south and west and smaller mallee and acacia-dominated vegetation to the north and east. The region has important populations of native animals that have dramatically declined elsewhere in Australia including the Western Quoll and Malleefowl. There is ongoing clearing for mining activities in the area, but also efforts to safeguard the ecoregion’s remarkable biodiversity through establishing more national parks and Indigenous Protected Areas.

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.

Salmon Gum
(Eucalyptus salmonophloia)

Short-beaked Echidna
(Tachyglossus aculeatus)

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.

Coolgardie Gum
(Eucalyptus torquata)

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.

Mount Holland Thomasia
(Thomasia gardneri)

Southwestern Grasswren
(Amytornis macrourus)

Australian Bustard
(Ardeotis australis)

Lord Howe Fantail
(Rhipidura cervina)

Lord Howe Thrush
(Turdus vinitinctus)

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

Mistletoebirds are important distributors of mistletoe seeds. There are over 90 species of mistletoes in Australia providing nectar-rich flowers to hundreds of types of animals. Mistletoebirds eat their fruits and spread the plants around, thus boosting biodiversity as they go.

Life-support Systems​

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