| Short description | Corymbia trachyphloia and Eucalyptus major woodland on igneous rocks |
| Structure code | Woodland |
| Description | Corymbia trachyphloia and Eucalyptus major dominate the open (25-40%) canopy (18-25m tall) with frequent subdominant canopy trees including Eucalyptus crebra, Eucalyptus fibrosa subsp. fibrosa, Eucalyptus montivaga and Lophostemon confertus. The very open (5-10%) sub-canopy (3-7m tall) is dominated by Callitris glaucophylla and Lophostemon confertus, and occasional vine forest species. The very sparse (5%) shrub layer (1-3m tall) is dominated by Acacia fimbriata, Dodonaea triangularis, Dillwynia sieberi, Leptospermum variabile and Bertya oleifolia. The ground layer comprises low shrubs in very open rocky areas (mainly Styphelia neoanglica and Zieria cytisoides 1-5%) and grasses in forested areas (10-30%). Occurs on hills and deeply dissected terrain. The surface varies from rocky outcrops to moderately deep texture-contrast soils. Not a Wetland. (BVG1M: 9h). |

| 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 very diverse understorey of this RE requires ground truthing or local knowledge before applying the fire guideline. The fire regime should maintain a mosaic of grassy and shrubby understoreys. |
| Comments | 12.8.26: Many of the species present are predominantly found in the granite belt region. Restricted to the south western edge of the Southeast Queensland bioregion. |
