| Short description | Corymbia clarksoniana +/- C. tessellaris open forest on metamorphic coastal ranges |
| Structure code | Open Forest |
| Description | Corymbia clarksoniana (Clarkson's bloodwood) open forest often with C. tessellaris (Moreton Bay ash) and Acacia polystachya subdominant. C. novoguinensis and C. intermedia (pink bloodwood) dominated at sites where C. clarksoniana was absent. The very sparse to mid-dense sub-canopy tree layer is dominated by Acacia flavescens (powder puff wattle), A. polystachya, A. crassicarpa (spoon tree) and Mallotus spp. The shrub layer (0.2-2m tall) varies from very sparse to dense with Antidesma ghaesembilla, Flueggea virosa subsp. melanthesoides and Planchonia careya (cocky apple) the most frequent dominant species. This layer may be dense in places and dominated by pioneer closed forest species. The ground layer varies from very sparse to dense with dominant species include Imperata cylindrica (blady grass), Panicum trichoides and Flemingia parviflora. Occurs on coastal metamorphic ranges. Not a Wetland. (BVG1M: 9c). |

| Fire management guidelines | SEASON: Commence planned burns early in the dry season, after the wet season when dry enough to burn. Use occasional storm burns but generally avoid periods of extremely hot, dry conditions. INTENSITY: Low to moderate with occasional high during storm burns. INTERVAL: 1-5 years. INTERVAL_MIN: 1. INTERVAL_MAX: 5. STRATEGY: Apply a mosaic across the landscape at a range of intervals to create varying stages of post-fire response. Burn 30-60% at the property level. ISSUES: To mitigate against the impact of late dry season fires, commence burning early in the season and continue through the dry to break up continuity of fuels across the landscape. Planned fire applied repeatedly early in the dry season may lead to woody thickening because fires are not of sufficiently high intensity; this may be exacerbated by stock grazing. Manage extent, intensity and frequency of fires judiciously, to avoid habitat tree loss. |
