Corner Country Bio-Regions

The Corner Country covers at least three distinct Bio-Regions.  Learn about each of them here.

The Broken Hill Complex Bioregion occupies a considerable land area and extends north, north-west and east from Broken Hill. Whilst the bioregion includes ranges such as the Scropes, Mootwingee
and Wonnaminta, it is the Barrier Range and the lower hills of the Grey Range, that are most dominant in the Corner Country. Many of the ranges are bounded by long faults producing prominent escarpments and deep gorges on the margins, whilst jump-ups andmesas occur in areas in the north west. read more

The Simpson-Strzelecki Dunefields Bioregion extends from the Northern Territory, through South Australia, into Queensland and New South Wales. It has been suggested that this is the largest example of a linear sand dune environment in the world. High dunes, varying from 50 metres to 500 metres apart, are interspersed by claypans and ephemeral lake beds. Most are stable and more than 30,000 years
old. The original source of sand is believed to be the Great Dividing Range. read more

The Channel Country Bioregion is an area of extensive stream systems with very wide flood plains. It extends across the Northern Territory, Queensland, South Australia and western New South Wales.
The Channel Country drains water from the Bulloo River, Cooper Creek, Lake Frome and Lake Bancannia. In New South Wales the land area is less than 5% of the total and includes significant
ephemeral wetlands, including the Bulloo Overflow, Carypundy Swamp and Salisbury Lake. read more
