The Western Australian Mulga shrublands is a large dry World Wildlife Fund ecoregion of inland Western Australia.[1]

Location and descriptionEdit

This is a hot, dry area with little rainfall.

The region consists of the Gascoyne, and Murchison bioregions of the Interim Biogeographic Regionalisation for Australia (IBRA).[2][3]

Flora and faunaEdit

The predominant vegetation is mulga trees, a type of acacia adapted to the hot, dry climate by means of long tap roots. In some areas the mulga trees are surrounded by Eriachne grassland.

Wildlife of the region includes birds such as emus, Australian bustards and honeyeaters.

Most of the area is uninhabited but there is some mining activity and some sheep grazing, both of which cause damage to native habitats.
