Location and description
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).[5][6]
Flora and fauna
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.
Protected areas
4.53% of the ecoregion is in protected areas. Protected areas in the ecoregion include:[1]
- Barlee Range Nature Reserve
- Birriliburu Indigenous Protected Area
- Bullock Holes Timber Reserve
- Collier Range National Park
