| Short description | Eucalyptus cullenii +/- Corymbia clarksoniana woodland or E. chlorophylla woodland on granitic ranges |
| Structure code | Woodland |
| Description | Woodland to low open woodland of Eucalyptus cullenii (Cullen's ironbark) +/- Corymbia clarksoniana (Clarkson's bloodwood) or open woodland of E. chlorophylla (shiny leaved box). Occurs on granites hills and footslopes. Not a Wetland. (BVG1M: 13a). Vegetation communities in this regional ecosystem include: 3.12.10a: Woodland to low open woodland of Eucalyptus cullenii (Cullen's ironbark) often with Corymbia clarksoniana (Clarkson's bloodwood) as a subdominant. E. tetrodonta or Erythrophleum chlorostachys may also be present, along with several other Corymbia spp. The very sparse to mid-dense subcanopy can contain canopy species, Melaleuca viridiflora (broad-leaved teatree), Brachychiton spp., Grevillea glauca (clothespeg Grevillea), Persoonia falcata (geebung) or Planchonia careya (cocky apple). In more hilly situations vine thicket species such as Dendrolobium umbellatum (horse bush), Canarium australianum (mango bark), Cochlospermum gillivraei (kapok) and Bridelia tomentosa can be present. A very sparse to mid-dense shrub layer often contains juvenile canopy species, Alphitonia pomaderroides (soapbush) or Dendrolobium umbellatum (horse bush). The mostly mid-dense grassy ground layer is usually dominated by Heteropogon spp., Sarga plumosum (plume sorghum) and Schizachyrium spp. (fire grass). Occurs on low to steep granite hills and footslopes. Not a Wetland. (BVG1M: 13a). 3.12.10b: Open woodland of Eucalyptus chlorophylla (shiny leaved box) and Corymbia dallachiana (Dallachy's gum) +/- C. confertiflora (cabbage gum) +/- Eucalyptus spp. Scattered canopy species can occur in the very sparse subcanopy and shrub layers along with Dendrolobium umbellatum (horse bush), Melaleuca viridiflora (broad-leaved teatree) and Persoonia falcata (geebung). The sparse to mid-dense grassy groundlayer can include Sarga plumosum (plume sorghum), Heteropogon spp., Schizachyrium fragile (fire grass) and Eriachne rara (Wanderrie grass). Occurs on granite hills. Not a Wetland. (BVG1M: 18c). 3.12.10c: [RE not in use]²: This vegetation community is now mapped as 3.12.10. Eucalyptus cullenii (Cullen's ironbark) and Corymbia dallachiana (Dallachy's gum) dominate the sparse to very sparse canopy (11-19m tall). Other Eucalyptus spp. may be present in the canopy and are occasionally subdominant. Dendrolobium umbellatum (horse bush) is the primary species in a very sparse sub-canopy layer (4-8m tall). The sparse shrub layer (0.2-1.5m tall) is characterised by the presence of Dolichandrone alternifolia (lemonwood), Flueggea virosa subsp. Melanthesoides (white currant) and Grevillea mimosoides. 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), and the forb Chamaecrista absus var. absus. Occurs on low granite hills and rises. Not a Wetland. (BVG1M: 13a). 3.12.10x2: [RE not in use]²: This proposed new regional ecosystem is now mapped as 3.12.44. Tall shrubs of Melaleuca citrolens (scrub teatree) usually with M. foliolosa (scale-leaved teatree) dominate the very sparse to sparse canopy (3-6m tall). Scattered emergent Excoecaria parvifolia (gutta percha) trees up to 10m tall are present in some areas. A sparse low shrub layer is usually present. The ground layer is short and very sparse, with Aristida spp. (three-awned speargrass), Eriachne spp. (wanderrie grass) and Fimbristylis spp. being the most commonly encountered species. Bare areas are common. Occurs on low granite hills. Not a Wetland. (BVG1M: 21b). |

| Special values | 3.12.10: Potential habitat for NCA listed species: Brachychiton grandiflorus, Cycas tuckeri, Dendrobium bigibbum, Dockrillia wassellii, Glossocardia orthochaeta. |
| 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. |
| Comments | 3.12.10: Occurs along the length of the Great Dividing Range. Also in small patches on ranges from Cooktown to the Altamoui Range. 3.12.10a: This vegetation community is unmappable and interspersed with vegetation community 3.12.10b. Occurs along the length of the Great Dividing Range. Also in small patches on ranges from Cooktown to the Altamoui Range. 3.12.10b: This vegetation community is unmappable and interspersed with vegetation community 3.12.10a. Occurs along the length of the Great Dividing Range. Also in small patches on ranges from Cooktown to the Altamoui Range. 3.12.10c: This vegetation community is unmappable and interspersed with vegetation community 3.12.10b and 3.12.10a. South west of Hann River. 3.12.10x2: Western part of bioregion. Extends into adjacent Gulf Plains bioregion. |
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.
