| Description | Corymbia nesophila (Melville Island bloodwood) woodland to open forest of commonly with Eucalyptus crebra (narrow-leaved ironbark) and E. tetrodonta (Darwin stringybark). There is usually a very sparse to sparse sub-canopy tree layer. The shrub layer ranges from very sparse to mid-dense (dependant on fire regime). Occurs on sandstone plateaus and slopes. Not a Wetland. (BVG1M: 14c). Vegetation communities in this regional ecosystem include: 3.10.21a: [RE not in use]²: This vegetation community is mapped as 3.10.21. Corymbia nesophila (Melville Island bloodwood) dominates the sparse canopy. Eucalyptus crebra (narrow-leaved ironbark) or E. tetrodonta (Darwin stringybark) may be present as a subdominant canopy tree. A number of other Eucalyptus spp. or Corymbia spp. may form minor components of the canopy. E. brassiana (Cape York red gum) may occur as a codominant canopy species in some areas. The very sparse sub-canopy tree layer is dominated by C. nesophila, Acacia flavescens (powder puff wattle), Lophostemon suaveolens (swamp mahogany) and Grevillea glauca (bushman's clothes peg). The shrub layer is very sparse. Acacia flavescens, Erythrophleum chlorostachys (Cooktown ironwood), C. nesophila and Persoonia falcata (geebung) are the most frequently encountered species. The ground layer varies from sparse to mid-dense. The dominant grasses are Themeda triandra (kangaroo grass), Eriachne pallescens (wanderrie grass), Aristida spp. (three-awned speargrass) and Heteropogon triticeus (giant speargrass). Common forbs include Spermacoce spp., Cyanthillium cinereum and Flemingia parviflora (flemingia). Occurs on sandstone plateaus. Not a Wetland. (BVG1M: 14c). 3.10.21b: [RE not in use]²: This vegetation community is mapped as 3.10.21. Corymbia nesophila (Melville Island bloodwood) dominates the sparse canopy. Eucalyptus crebra (narrow-leaved ironbark) may be present as a subdominant canopy tree. A number of other Eucalyptus spp. or Corymbia spp. may form minor components of the canopy. E. brassiana (Cape York red gum) occurs as a codominant canopy species at a number of sites. The very sparse sub-canopy tree layer is dominated by C. nesophila, Acacia flavescens (powder puff wattle), Lophostemon suaveolens (swamp mahogany) and Grevillea glauca (bushman's clothes peg). The shrub layer is very sparse. A. flavescens, Erythrophleum chlorostachys (Cooktown ironwood), C. nesophila and Persoonia falcata (geebung) are the most frequently encountered species. The ground layer varies from sparse to mid-dense. The dominant grasses are Themeda triandra (kangaroo grass), Eriachne pallescens (wanderrie grass), Aristida spp. (three-awned speargrass) and Heteropogon triticeus (giant speargrass). Common forbs include Spermacoce spp., Cyanthillium cinereum and Flemingia parviflora (flemingia). Occurs on sandstone slopes. Not a Wetland. (BVG1M: 14c). 3.10.21c: [RE not in use]²: This vegetation community is mapped as 3.10.6a. Eucalyptus tetrodonta (Darwin stringybark) and either Corymbia nesophila (Melville Island bloodwood) or C. stockeri subsp. peninsularis (gum-topped bloodwood) usually co dominate to form the canopy (13-28m tall). E. leptophleba (Molloy red box) and sometimes C. clarksoniana (Clarkson's bloodwood) occur as scattered canopy or sub-canopy trees. Erythrophleum chlorostachys (Cooktown ironwood) and C. confertiflora (cabbage gum) frequently form a very sparse to sparse sub-canopy layer (12-18m tall). Acacia rothii (Roth's wattle), Melaleuca viridiflora (broad-leaved teatree), Grevillea glauca (bushman's clothes peg) and Petalostigma spp. (quinine) are also abundant in the sub-canopy layer but usually reach only 3-8m in height. A very sparse to mid-dense shrub layer (0.5-2m tall) dominated by shrubs and shrubby trees is always present. The ground layer is sparse to mid-dense and dominated by the grasses Schizachyrium spp. (fire grass), Sarga plumosum (plume sorghum), Heteropogon triticeus (giant speargrass) and Thaumastochloa spp. frequent dominants. Occurs on sandstone slopes and plateaus. Not a Wetland. (BVG1M: 14a). |

| 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. |

1 Estimated extent is from version 13.1 pre-clearing and 2021 remnant regional ecosystem mapping. Figures are rounded for simplicity. For more precise estimates, including breakdowns by tenure and other themes see remnant vegetation in Queensland.
2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use. It is included in the regional ecosystem description database because the RE code may appear in older versions of RE mapping and the Vegetation Management regulation.
