| Structure code | Woodland |
| Description | Eucalyptus cullenii (Cullen's ironbark) woodland to low woodland commonly with Corymbia clarksoniana (Clarkson's bloodwood). Other Eucalyptus spp. and Corymbia spp. may be present in the canopy and are occasionally subdominant. Erythrophleum chlorostachys is also common in the both the canopy and very sparse subcanopy. The very sparse shrub layer is characterised by the presence of Dolichandrone alternifolia (lemonwood) and scattered canopy species. The ground layer is sparse to mid-dense and dominated by the grasses, Heteropogon contortus (black speargrass), H. triticeus (giant speargrass) and Sarga plumosum (plume sorghum). Occurs on low hills and rises on metamorphic rocks. Not a Wetland. (BVG1M: 13a). |

| Special values | 3.11.7: Potential habitat for NCA listed species: Cycas tuckeri. |
| Fire management guidelines | SEASON: Dry season with occasional storm burns. INTENSITY: Low to moderate with occasional high intensity. INTERVAL: 1-5 years. INTERVAL_MIN: 1. INTERVAL_MAX: 5. STRATEGY: Burn less than 30% in any year. Begin burning early in the dry season, followed by progressive patch fires burnt through the year. ISSUES: This vegetation is fire tolerant. Management should aim at preventing extensive wildfire. Storm burns are used to add diversity to the fire mosaic, promoting perennial grasses and preventing vegetation thickening. |
