Victoria Plains tropical savanna

Australia

A west-east spreading expanse of rich savanna grasslands and open woodlands interspersed with amazing geological formations from ancient weather sandstones to volcanic mesas. The area contains many interesting species with a wide variety of different micro-habitats supporting endemic species (found nowhere else on earth).

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 common across the region such as River Red Gum (Eucalyptus camaldulensis) and Weeping Ghost Gum (Corymbia bella) if you have space. In damper areas, try the local-endemic Victoria River Palm (Livistona victoriae). 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 Wild Plum (Terminalia platyphylla), Northern Milkwood (Alstonia actinophylla), Kerosene Wood (Cordia subcordata) and Cocky Apple (Planchonia careya). To create habitat, consider installation of nestboxes for native birds and creating tree hollows in old, dead tree limbs.

SHRUB LAYER

Plant native shrubs such as Acacia torulosa, Graceful Cassia (Senna venusta), and Wickham's Grevillea (Grevillea wickhamii). 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.

GROUND LAYER

Plant tuft-forming grasses in swathes such as Triodia epactia and Triodia schinzii which form great features between shrubs and trees. For colour, try Green Birdflower (Crotalaria cunninghamii), Pink Mulla Mulla (Ptilotus exaltatus), Sturt's Desert-rose (Hibiscus sturtii) and Green Pussytails (Ptilotus macropcephalus). 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 large expanse of open savanna grasslands with scattered woodlands of important Lancewood and Bullwaddy trees predominates much of the region. There are areas of stunning geological formation such as the Bungle Bungles in Purnululu National Park which provide cooler, moister conditions where small rainforests and riparian vegetation persists. A wealth of arid-loving species occur in the region including many species of burrowing-frogs, reptiles and rock-climbing possums. Along waterways such as the Victoria River, areas of palm groves occur with high bird diversity including a number of water-birds and interesting finches. The area is under threat from continued grazing and escape of feral grazing animals like cows and buffalo.

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.

Geology

Western areas dominated by clay and red loam soils with sandstone outcrops while in the east, largely flat, red-sandy loam soil plateaus and occasional mesas

Climate

Tropical - Subtropical

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

Budgerigars are nomadic flock parakeets that travel often huge distances between areas of ripe grass seeds and water. As such, they spread grass seeds over huge distances in their droppings and help maintain native grassland health in this way.

Life-support Systems​

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