Jarrah-Karri forest and shrublands


A slender, coastal ecoregion along the base of south-west Western Australia. The area is defined by the tall open forests of Jarrah and Karri trees along with gorgeous coastal swamps, heaths and beaches.

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!


Food and Homeware: Albany Eco House


Holidays: Jarrah Forest Lodge

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 trees that are characteristic of this ecoregion like the mighty Karri (Eucalyptus diversicolor), Jarrah (Eucalyptus marginata), Marri (Corymbia calophylla), Tingle (Eucalyptus brevistylis) and Red Tingle (Eucalyptus jacksoni) if you have space. To create habitat, consider installation of nestboxes for native birds and creating hollows in old, dead tree limbs.


Plant native sub-canopy trees that are small and have interesting growth-forms like Callitris canescens, bright Red-flowering Gum (Corymbia ficifolia), Acorn Banksia (Banksia prionotes), Coastal Dune Wattle (Acacia littorea) and Scarlet Bottlebrush (Melaleuca phoenicea). To create habitat, consider installation of nestboxes for native birds and creating tree hollows in old, dead tree limbs.


Plant native shrubs like Sandpaper Wattle (Acacia denticulosa), Yellow Tailflower (Anthocercis littorea), Couch Honeypot (Banksia nivea), Water Bush (Bossiaea aquifolium), Southern Diplolaena (Diplolaena dampieri) and the beautiful mauve-flowering Kunzea recurva and Kunzea rostrata. 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 an array of thick ground-covers like Lake King Eremophila (Eremophila subteretifolia), Pallinup Gold (Acacia declinata), Kidney-weed (Dichondra repens), Native Wisteria (Hardenbergia comptoniana), Foxtails (Andersonia caerulea) and Cut-leaved Guinea-flower (Hibbertia cuneiformis). 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.


The mighty Jarrah and Karri forests of Western Australia are a sight to behold. A stronghold for wetter-climate species within a Mediterranean biome, this ecoregion has become separated from other similar regions by its arid interior and dry coastal fringe. The result is a bastion of diversity, including hugely important forests (much of which were heavily logged by early colonisers) and isolated populations of rare native mammals. Some of the forests contain remnant trees many hundreds of years old; many of which tower above the surrounding landscape and comprise some of Australia’s tallest individuals. Frog species are also represented here with several found nowhere else on earth like the brightly-coloured Sunset Frog. While quite a large proportion of the ecoregion is protected in national parks, still large areas have been, and continue to be transformed through persistent logging and fragmentation by agriculture.

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.

Brown Boronia
(Boronia megastigma)

Albany Pitcher-plant
(Cephalotus follicularis)

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.

Nullarbor Barred Bandicoot
(Perameles papillon)

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

Brush-tailed Phascogales occur in the Jarrah-Karri forests of Western Australia and are important omnivores. They eat everything from nectar to small rodents and are therefore important food-chain components.

Life-support Systems​

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