Nandewar bioregion area
- 2,701,977 hectares in total
- 2,072,816 hectares in NSW
The Nandewar Bioregion lies in northern NSW and across the Qld border. The bioregion is bounded by the North Coast, New England Tablelands and Brigalow Belt South bioregions in the south, east and west respectively.
Part of the MacIntyre, Gwydir and Namoi catchments are located in the Nandewar bioregion and the Peel, Macdonald, McIntyre, Namoi, Severn and Gwydir rivers flow through it.
The Nandewar bioregion is mostly fairly warm and dry, although average annual temperatures and rainfall vary considerably across the bioregion in relation to elevation.
The bioregion is characterised by box woodlands that occur on clay or loam soils, typically at low to mid elevation in agriculturally productive areas. With decreasing soil fertility and increasing topographic relief the box woodlands are replaced by ironbark/cypress pine communities which characterise much of the agriculturally less productive parts of Nandewar.
A small proportion of the NSW part of the Nandewar bioregion is managed under various conservation regimes, with the majority being national parks and nature reserves. There are some State forests in the region.
