| Short description | Corymbia citriodora subsp. variegata +/- Eucalyptus crebra open forest on sedimentary rocks |
| Structure code | Open Forest |
| Description | Corymbia citriodora subsp. variegata open forest or woodland usually with Eucalyptus crebra. Other species such as Eucalyptus tereticornis, E. moluccana, E. acmenoides and E. siderophloia may be present in scattered patches or in low densities. Understorey can be grassy or shrubby. Shrubby understorey of Lophostemon confertus (whipstick form) often present in northern parts of bioregion. Occurs on Cainozoic and Mesozoic sediments. Not a Wetland. (BVG1M: 10b). |

| Special values | 12.9-10.2: Habitat for threatened plant species including Notelaea lloydii, Grevillea quadricauda, Westringia sericea, Coleus habrophyllus. 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. Control of weeds (e.g., Lantana camara, asparagus fern Asparagus africanus, balloon cotton-bush Gomphocarpus physocarpus) with fire might be required. There is evidence that the spiral leaf Macrozamias (e.g. M. parcifolia) decline in health if fire interval is greater than 6 years. |
| Comments | 12.9-10.2: Typically occurs in drier sub-coastal environments and is less species rich than 12.9-10.17b. |
