| Description | Eucalyptus crebra, Corymbia erythrophloia, C. dallachiana and C. tessellaris +/- C. intermedia +/- E. acmenoides +/- Canarium australianum mixed woodland or open forest.

Vegetation communities in this regional ecosystem include: 11.12.13a: Eucalyptus acmenoides, E. drepanophylla +/- E. exserta woodland. Coastal hills and ranges on often rocky acid-volcanic derived soils. Not a Wetland. (BVG1M: 10a). 11.12.13b: Corymbia intermedia, Allocasuarina torulosa, Syncarpia glomulifera subsp. glomulifera and Eucalyptus acmenoides open forest. Coastal hills and ranges, always on loamy soils with abundant surface rock. Occurs consistently at elevations above 300 HASL. Not a Wetland. (BVG1M: 9h). |

| Fire management guidelines | SEASON: Early dry season when there is good soil moisture, with some later fires in the early storm season or after good spring rains. INTENSITY: Various. INTERVAL: 5-10 years. INTERVAL_MIN: 5. INTERVAL_MAX: 10. STRATEGY: A predominance of early dry season fires is recommended, although there is value in occasional late dry season fires, or storm burns, over small areas. Burning should begin fairly soon after the wet season. Where possible, ignite initial fires from upper ridges to burn down. Multiple dates of ignition within the same forest area will produce a mosaic of burnt landscape. ISSUES: Avoid ignition such that fires burn from the bottom of hills upwards. Too frequent fires may eliminate fire-killed shrubs and small trees (such as Casuarinas). Once boundaries are secured with early fires, late dry season and storm-burning may provide the intensity required to enhance seed germination of many species, but restrict spread and allow the creation and maintenance of a multi-aged mosaic. Ensure moderate densities of mature casuarinas, cypress pine and wattles are maintained; ensure the persistence of large eucalypts. |
