Darling Riverine Plains Bioregion

The Darling Riverine Plains Bioregion occupies a total area of 10,651,748 hectares in northern NSW and Qld. The majority of the bioregion, 88.19 per cent (9,394,263 ha), is in NSW and it occupies 11.74 per cent of the state.

The bioregion is surrounded by 6 others in both NSW and Qld, including the Brigalow Belt South Bioregion to the east, the Mulga Lands Bioregion to the northwest, and the NSW Southwestern Slopes, Cobar Peneplain, Murray Darling Depression and Broken Hill Complex bioregions in the south and southwest.

The bioregion forms a bulky shape that extends into Qld, with a long, narrow riverine corridor that runs southwest along the Darling River. The main body of the bioregion extends from east of Bogabilla to Weilmoringle on the Qld border, south almost to Peak Hill and west to Nyngan and Bourke. The bioregion is traversed by the Western Division boundary.

In central north NSW, the Darling Riverine Plains Bioregion includes the lower reaches and alluvial fans of the Bogan, Macquarie, Castlereagh, Namoi, Barwon, Culgoa, Bokhara, Narran, Gwydir and Macintyre Rivers (Morgan and Terrey 1992).

The Darling River corridor extends from Bourke almost to the southern edge of the Menindee Lakes, and south through the Murray Darling Depression Bioregion to the Victorian border where the Darling joins the Murray River.

The bioregion falls entirely in the Murray-Darling Basin and includes the Macintyre-Dumaresq, Culgoa, Narran, Warrego, Paroo, Moonie, Barwon, Gwydir, Namoi, Macquarie, Yanda, Castlereagh and Darling catchments.
