The South West Slopes is a region predominantly in New South Wales, Australia. It covers the lower inland slopes of the Great Dividing Range extending from north of Cowra through southern NSW into western Victoria. More than 90% of the region is in the state of New South Wales and it occupies about 10% of that state.

Map of the bioregion

The south western slopes bioregion covers the lower inland slopes of the Great Dividing Range extending from north of Cowra through southern NSW into western Victoria. More than 90% of the region is in the state of New South Wales and it occupies about 10% of that state - more than 80,000 km². ^[1][2]

The bioregion includes parts of the Murray, Murrumbidgee, Lachlan and Macquarie River catchments.^[3]

The region can be divided into two sub-regions: ^[4]

• Northern Inland Slopes subregion
• Lower Slopes subregion

The South western Slopes of NSW are some of the most highly cleared and altered lands in the state. Native vegetation remains generally only in small, isolated patches. Substantial clearing continues. Less than 2% of the bioregion is protected as reserves. Conservation efforts are focussing on landholder stewardship agreements. ^[4][5]
