| Description | Corymbia clarksoniana (Clarkson's bloodwood) and Eucalyptus tetrodonta (Darwin stringybark) woodland to low woodland occasionally with Melaleuca viridiflora (broad-leaved teatree), M. nervosa and Erythrophleum chlorostachys (Cooktown ironwood). A very sparse subcanopy commonly contains Melaleuca spp. canopy species. The very sparse shrublayer usually contains scattered canopy species, Grevillea glauca (clothespeg Grevillea) and Acacia spp. The mid-dense grassy ground layer is commonly dominated by Heteropogon triticeus (giant spear grass), Schizachyrium spp., and Themeda triandra (kangaroo grass). Occurs on sandstone plateaus. Not a Wetland. (BVG1M: 14d). Vegetation communities in this regional ecosystem include: 3.10.9a: [RE not in use]²: This vegetation community is now mapped as 3.10.6a. Eucalyptus tetrodonta (Darwin stringybark) and Corymbia stockeri subsp. stockeri (gum-topped bloodwood) co dominate the sparse canopy (12-17m tall). E. cullenii (Cullen's ironbark) and Erythrophleum chlorostachys (Cooktown ironwood) are occasionally present as subdominant trees. The very sparse sub-canopy layer (2-6m tall) is dominated by the canopy eucalypts. A very sparse shrub layer (0.5-1m tall) is present where C. stockeri subsp. stockeri, Eucalyptus tetrodonta, Grevillea dryandri subsp. dryandri, Indigofera pratensis (forest indigo) and Persoonia falcata (geebung) are the most commonly encountered species. The ground layer is sparse and dominated by the grasses Triodia microstachya (spinifex), Eriachne spp., Heteropogon triticeus (giant speargrass) and Themeda triandra (kangaroo grass). Occurs on sandstone plateaus. Not a Wetland. (BVG1M: 14d). 3.10.9b: [RE not in use]²: This vegetation community is now mapped as 3.10.9. Eucalyptus tetrodonta (Darwin stringybark) predominates forming a sparse canopy. Corymbia clarksoniana (Clarkson's bloodwood) is often present and sometimes codominant in the canopy. Erythrophleum chlorostachys (Cooktown ironwood) is also frequently present in both the canopy and the very sparse to sparse sub-canopy tree layer. Grevillea glauca (bushman's clothes peg), Erythroxylum ellipticum (matchwood), Alphitonia pomaderroides (soapwood), Eucalyptus tetrodonta and Melaleuca nervosa (woodland paperbark) are other common sub-canopy trees. A very sparse to sparse shrub layer is composed of a variety of young trees and shrubby regrowth. The ground layer is usually very sparse to mid-dense and dominated by grasses, usually Schizachyrium spp. (firegrass), Sarga plumosum (plume sorghum), Panicum spp. (native panic), Aristida spp. (three-awn speargrass), Alloteropsis semialata (cockatoo grass) and Thaumastochloa spp. On sandstone ranges. Not a Wetland. (BVG1M: 14d). 3.10.9c: [RE not in use]²: This vegetation community is now mapped as 3.10.9. Eucalyptus tetrodonta (Darwin stringybark) predominates forming a sparse to mid-dense canopy. Corymbia clarksoniana (Clarkson's bloodwood) is often present and sometimes codominant in the canopy. C. tessellaris (Moreton Bay ash) and Lophostemon suaveolens (swamp mahogany) are also frequently present in the canopy. The very sparse to sparse sub-canopy tree layer is dominated by Acacia flavescens (powderpuff wattle), Parinari nonda (nonda plum), Grevillea parallela (silver oak), Erythrophleum chlorostachys (Cooktown ironwood) and Melaleuca viridiflora (broad-leaved teatree). Livistona muelleri (dwarf fan palm) is common in the sub-canopy tree layer and dominated this layer at one site. The very sparse shrub layer is composed of a variety of young trees and shrubby regrowth. The ground layer is usually sparse to mid-dense and frequently dominated by Heteropogon triticeus (giant speargrass), Mnesithea rottboellioides (northern cane grass), Dianella spp., Imperata cylindrica (blady grass) and Sarga plumosum (plume sorghum). Occurs on sandstone ranges. Not a Wetland. (BVG1M: 14d). 3.10.9d: [RE not in use]²: This vegetation community is now mapped as 3.10.6a. Eucalyptus tetrodonta (Darwin stringybark) predominates, forming a distinct but discontinuous sparse canopy (17-26m tall). Corymbia nesophila (Melville Island bloodwood) and C. clarksoniana (Clarkson's bloodwood) may be subdominant in the canopy. Erythrophleum chlorostachys (Cooktown ironwood) may occur just below the canopy, occasionally forming a mid-dense layer. sub-canopy trees (4-15m tall) are sometimes present. A sparse low shrub layer (0.5-2m tall) composed of young trees and shrubby regrowth is often present. The ground layer can be very sparse to mid-dense and is dominated by grasses. The primary species in this layer are Schizachyrium spp. (fire grass), Sarga plumosum (plume sorghum), Panicum spp. (native panics), Alloteropsis semialata (cockatoo grass) and Thaumastochloa spp. Occurs on sandstone footslopes and hills. Not a Wetland. (BVG1M: 14a). 3.10.9e: [RE not in use]²: This vegetation community is now mapped as 3.5.9. Eucalyptus tetrodonta (Darwin stringybark) is always present in the sparse canopy (13-22m tall). It usually predominates or is codominant with Corymbia stockeri subsp. Stockeri (gum-topped bloodwood) and/or C. setosa subsp. Pedicellaris (rough-leaved bloodwood). Erythrophleum chlorostachys (Cooktown ironwood) is also often present in both the canopy and the very sparse to sparse sub-canopy tree layer (3-12m tall). Grevillea glauca (bushman's clothes peg), G. parallela (silver oak), Neofabricia sericisepala, Petalostigma banksii (smooth-leaved quinine), Adenanthera abrosperma (bead tree), Corymbia stockeri subsp. Peninsularis, C. setosa subsp. Pedicellaris, Eucalyptus tetrodonta and Melaleuca nervosa (paperbark) are other frequent sub-canopy trees. A very sparse to sparse shrub layer (0.2-2.5m tall) is composed of a variety of young trees and shrubby regrowth. The ground layer is usually sparse to mid-dense and dominated by grasses usually Schizachyrium spp. (fire grass), Sarga plumosum (plume sorghum), Panicum spp. (panic), Aristida spp. (three-awned speargrass), Eriachne spp. (wanderrie grass) and Thaumastochloa spp. Occurs on sandstones. Not a Wetland. (BVG1M: 14b). |

| Special values | 3.10.9: Potential habitat for NCA listed species: Acacia guymeri, Cucumis costatus, Dianella incollata, Homoranthus tropicus, Stemona angusta, Stenanthemum argenteum. |
| 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 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.
