South-west Australia woodlands


This ecoregion occurs within the Southwest Australia global biodiversity hotspot and as such is a hotbed of biological diversity. From high endemism to primary forests and from relict populations to ancient living fossils.

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!


Construction: Witchcliffe EcoVillage
Construction: Sustainable Tradies

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 a range of characteristic large trees such as Marri (Corymbia calophylla), Smooth-bark Wandoo (Eucalyptus accedens) and the beautiful, slightly smaller Wanil (Agonis flexuosa). To create habitat, consider installation of nestboxes for native birds and creating hollows in old, dead tree limbs.


Plant native sub-canopy trees like the Rottnest Island Pine (Callitris pressii), the insanely bright Red-flowering Gum (Corymbia ficifolia), lovely lemon-coloured Illyarrie (Eucalyptus erythrocorys), Moonah (Melaleuca lanceolata) and the Coastal Blackbutt (Eucalyptus todtiana) in coastal areas. Tall banksias such as the Firewood Banksia (Banksia menziesii), Acorn Banksia (Banksia prionotes) and Parrotbush (Banksia sessilis) are stunning, architectural plants to add. 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 statuesque Balga (Xanthorrhoea preissii), Common Hovea (Hovea trisperma), One-sided Bottlebrush (Calothamnus quadrifidus), Swan River Myrtle (Hypocalymma robustum), Yanchep Rose (Diplolaena angustifolia), Thryptomene baeckeacea, Stalked Guinea-flower (Hibbertia racemosa), False Boronia (Phyllanthus calycinus) and the amazing Grevillea crithmifolia. 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.


Plant colourful natives that bring in the pollinators, like Native Wisteria (Hardenbergia comptoniana), Dangalang (Rhodanthe chlorocephala), Blue Lechenaultia (Lechenaultia biloba), Coral Vine (Kennedia coccinea), Snakebush (Hemiandra pungens) and Conostylis candicans. For a vivid colour-pallette that will attract native birds, try Little Kangaroo-paw (Anigozanthos bicolor), Green Kangaroo-paw (Anigozanthos viridis), Red Lechenaultia (Lechenaultia formosa), and in coastal areas, Sarcozona (Sarcozona praecox). 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 found between Jurien Bay to the north of Perth and Narrikup in the south (just above Albany). The ecoregion is teeming with life and contains over 3,500 native plant species along with over 200 species of birds and 140 species of reptiles. The area is characterised by a large eastern plateau which extends into ranges and valleys, while on the western seaboard, the Swan Coastal Plain spreads out north and south of Perth. The region has a high degree of habitat loss due to past logging, the creation of Peth and its surrounding suburbs and agriculture along the fertile soils of the plains. Sadly, many of the regions most remarkable species are now listed as threatened under state and national law.

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.
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

The Warrine, or Native Yam, is an important edible plant bearing carbohydrate-rich tubers underground, often over large areas. This species is a significant food-source and a source of hydration.

Life-support Systems​

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