| Short description | Corymbia citriodora subsp. variegata, Eucalyptus crebra woodland on metamorphics +/- interbedded volcanics |
| Structure code | Woodland |
| Description | Open forest to woodland of Corymbia citriodora subsp. variegata generally with Eucalyptus crebra. Other species such as Eucalyptus exserta, E. tereticornis, E. moluccana, E. melanophloia, E. acmenoides, Corymbia tessellaris and Angophora leiocarpa may be present in scattered patches or in low densities. Understorey grassy or shrubby. Occurs on Palaeozoic and older moderately to strongly deformed and metamorphosed sediments and interbedded volcanics. Drier habitats than RE 12.11.5. Not a Wetland. (BVG1M: 10b). |

| Special values | 12.11.6: Habitat for threatened flora species including Cycas megacarpa and Macrozamia parcifolia. This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). |
| Fire management guidelines | SEASON: Summer to winter. INTENSITY: Low to moderate. INTERVAL: 4-25 years. INTERVAL_MIN: 4. INTERVAL_MAX: 25. STRATEGY: Aim for 40-60% mosaic burn. Burn with soil moisture and with a spot ignition strategy so that a patchwork of burnt/unburnt country is achieved. Variability in season and fire intensity is important. ISSUES: The fire regime should maintain a mosaic of grassy and shrubby understoreys. |
| Comments | 12.11.6: This RE has been compiled from individual 1:100 000 map sheets in addition to the units in Sparshott et al. (1997). |
1 Estimated extent is from version 13 pre-clearing and 2021 remnant regional ecosystem mapping. Figures are rounded for simplicity. For more precise estimates, including breakdowns by tenure and other themes see remnant vegetation in Queensland.
