| Structure code | Woodland |
| Description | Mixed woodland to low woodland, including combinations of the species Eucalyptus camaldulensis, Terminalia platyphylla, Corymbia bella, E. microtheca, E. chlorophylla and Corymbia confertiflora. A lower tree or shrub layer may occur, including canopy species and Dendrolobium arbuscula. The ground layer primarily tussock grasses, including Heteropogon contortus, Enteropogon minutus and Oryza australiensis. Occurs on fringes of minor watercourses in Cretaceous mudstone landscapes. Cracking clay soils. Riverine. (BVG1M: 27c). Vegetation communities in this regional ecosystem include: 2.3.6a: Mixed woodland to low woodland, including combinations of the species Eucalyptus camaldulensis, Terminalia platyphylla, E. chlorophylla and C. confertiflora. A lower tree or shrub layer may occur, including Dendrolobium arbuscula and Dolichandrone heterophylla. The ground layer is tussock grasses. Occurs on minor watercourses with fine-grained parent material derived from Cretaceous mudstone in the north-east of the bioregion. Riverine. (BVG1M: 27c). 2.3.6b: Mixed low woodland to low open forest, including combinations of the species Eucalyptus camaldulensis, Terminalia platyphylla, Corymbia bella, E. microtheca and C. confertiflora. The ground layer is tussock grasses. Occurs on minor watercourses with fine-grained parent material in dissected lateritic landscapes in the west of the bioregion. Riverine. (BVG1M: 27c). 2.3.6x1: [RE not in use]²: This vegetation community is now mapped as 2.3.44e. Mixed tussock grasslands, including combinations of the species Chloris spp., Dichanthium spp., Dinebra neesii, Bothriochloa bladhii subsp. bladhii, Aristida latifolia, Panicum spp., Oryza australiensis, Ectrosia scabrida and Cenchrus basedowii. Emergent Vachellia bidwillii, Lysiphyllum cunninghamii and Excoecaria parvifolia may occur. Occurs on Quaternary alluvial plains derived from fine-grained parent material. Grey to brown cracking clay soils. Not a Wetland. (BVG1M: 30a). |

| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Exclude fire, wherever possible. Buffer as indicated by fuel build-up in surrounding vegetation. ISSUES: Species in this vegetation unit may be eliminated by fire. |
| Comments | 2.3.6: Survey required to verify condition. Subject to invasion by *Cryptostegia grandiflora (rubber vine). 2.3.6a: Survey required to verify condition. Subject to invasion by *Cryptostegia grandiflora (rubber vine). 2.3.6b: Survey required to verify condition. Subject to invasion by *Cryptostegia grandiflora (rubber vine). 2.3.6x1: May be invaded by *Cryptostegia grandiflora (rubber vine). Some areas are subject to degradation from high total grazing pressure. |
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.
