New England Tablelands (code NET),an interim Australian bioregion, is located mainly in New South Wales,[4][5] comprising 3,002,213 hectares (7,418,630 acres),[2] of which 2,860,758 hectares (7,069,090 acres) or 95.23 per cent of the bioregion lies within New South Wales; and the residual within Queensland. This bioregion is one of the smaller bioregions in NSW, occupying 3.57 per cent of the state.[6]

The New England Tableland Bioregion is a stepped plateau of hills and plains with elevations between 600 and 1,500 metres (2,000 and 4,900 ft) on Permian sedimentary rocks, intrusive granites and extensive Tertiary basalts.[1] Rainfall varies considerably from 653 to 1,765 millimetres (25.7 to 69.5 in)[3] and mean temperatures range from −3 to 17 °C (27 to 63 °F),[3] based on changes with topography. In terms of plants, the region is dominated by stringy bark/box/peppermint species, including Eucalyptus caliginosa, E. nova-anglica, E. melliodora and E. blakelyi.[7]
