| Short description | Corymbia nesophila +/- Eucalyptus spp. open forest on wetter ranges in south-east |
| Structure code | Open Forest |
| Description | Corymbia nesophila (Melville Island bloodwood) open forest usually with C. intermedia (pink bloodwood). A number of other Eucalypts may form minor components of the canopy. The very sparse to mid-dense sub-canopy tree layer is dominated by Acacia flavescens (powder puff wattle), A. crassicarpa (spoon tree), Lophostemon suaveolens (swamp mahogany), C. nesophila, Erythrophleum chlorostachys (Cooktown ironwood) and Allocasuarina littoralis (black sheoak). Scattered Planchonia careya and Alphitonia pomaderroides low trees form a sparse layer. The shrub layer varies from very sparse to mid-dense. Acacia crassicarpa, A. flavescens, Erythrophleum chlorostachys, C. nesophila, Alphitonia pomaderroides (soapbush) and Planchonia careya (cocky apple) are the most commonly encountered dominant species in this layer. Themeda triandra (kangaroo grass), Eriachne triseta, Imperata cylindrica (blady grass) and Heteropogon triticeus (giant speargrass) are frequent dominant species in the very sparse to mid-dense ground layer. Occurs on hills and ranges. Not a Wetland. (BVG1M: 14c). |

| 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: 2-5 years. INTERVAL_MIN: 2. 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. |
