| Structure code | Woodland |
| Description | Woodland to open forest of Eucalyptus fibrosa subsp. fibrosa and/or Corymbia trachyphloia subsp. trachyphloia +/- C. citriodora subsp. variegata, E. acmenoides or E. apothalassica, E. decorticans, E. crebra, E. exserta, Lysicarpus angustifolius and Acacia spp. Occurs on duricrusted land surfaces including crests with shallow soils and breakaway areas. Not a Wetland. (BVG1M: 12a). |

| Fire management guidelines | SEASON: Late summer to winter. INTENSITY: Low to moderate. INTERVAL: 7-15 years. INTERVAL_MIN: 7. INTERVAL_MAX: 15. STRATEGY: Aim for a burn mosaic of 40-60% over the burn area. A diversity of season and fire intensity is important, as well as spot ignition in cooler or moister periods to encourage mosaics. Late summer burns assist with maintaining control of fire intensity. ISSUES: Fires that are too frequent will eliminate obligate seeding species. Fire frequency should be such as to allow trees to reach maturity and produce viable seed. |
| Comments | 12.7.1: Mostly restricted to western margins of central part of bioregion in the vicinity of Barambah Creek extending westward into the Brigalow Belt. Small isolated patches elsewhere, e.g. Wondai State Forest (SF) and vicinity of Cordalba SF. |
