Eucalyptus tetrodonta (Darwin stringybark) predominates forming a sparse to mid-dense canopy (14-26m tall). 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 (3-15m tall) 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 (0.5-2m tall) 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 granite ranges. Not a Wetland. (BVG1M: 14d). 3.12.15x1b: [RE not in use]²: This proposed new vegetation community is now mapped as 3.12.40. Eucalyptus tetrodonta (Darwin stringybark) and Corymbia nesophila (Melville Island bloodwood) dominate the very sparse to mid-dense canopy (10-28m tall). In most situations both species are present and codominant, however, C. nesophila may be dominant or occasionally absent. Corymbia stockeri subsp. peninsularis (gum-topped bloodwood) is sometimes present in the canopy. A very sparse to sparse sub-canopy tree layer (8-20m tall) is present with Erythrophleum chlorostachys (Cooktown ironwood), just below the canopy, Grevillea glauca (bushman's clothes peg), Parinari nonda (nonda plum) and Acacia rothii (Roth's wattle) the most frequent species. A very sparse low tree layer (2-8m tall) is sometimes present. The shrub layer (0.3-2.5m tall) is dominated mainly by species that also occur in the tree layers and is sparse to mid-dense. The shrub layer of recently burnt areas is usually mid-dense. The ground layer is sparse to mid-dense and dominated by grasses. Heteropogon triticeus (giant speargrass), Sarga plumosum (plume sorghum), Thaumastochloa spp. and Eriachne spp. (wanderrie grass) frequently dominating the ground layer biomass. Occurs on granite ranges. Not a Wetland. (BVG1M: 14d). 3.12.15x1c: [RE not in use]²: This proposed new vegetation community is now mapped as 3.12.41. Eucalyptus tetrodonta (Darwin stringybark) predominates forming a distinct but discontinuous canopy (9-25m tall). Corymbia nesophila (Melville Island bloodwood) is a subdominant to codominant canopy species. A very sparse to sparse sub-canopy layer (5-12m tall) is characterised by Asteromyrtus brassii, Neofabricia myrtifolia (yellow teatree), Grevillea glauca (bushman's clothes peg) and Acacia rothii (Roth's wattle). Scattered low trees (2-6m tall) are sometimes present and a very sparse to mid-dense shrub layer (0.5-2m tall) is dominated by heath shrubs such as Jacksonia thesioides, Neoroepera banksii, Choriceras tricorne (Cape choriceras), Asteromyrtus lysicephala (back to front bush) and Acacia calyculata (a wattle). These often occur at high densities. The ground layer is usually very sparse to mid-dense and dominated by the sedge Schoenus sparteus and the grasses Heteropogon triticeus (giant speargrass) and Eulalia mackinlayi (silky browntop). Occurs on granite ranges. Not a Wetland. (BVG1M: 14d). 3.12.15x2a: [RE not in use]²: This proposed new vegetation community is now mapped as 3.12.42. Eucalyptus tetrodonta (Darwin stringybark) predominates forming a sparse canopy (12-28m tall). 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 (3-14m tall). 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 (0.3-2.5m tall) 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. Occurs on sandy soil on eroded granite. Not a Wetland. (BVG1M: 14d). 3.12.15x2b: [RE not in use]²: This proposed new vegetation community is now mapped as 3.12.42. 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 low granite hills. Not a Wetland. (BVG1M: 14a). |

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.
