| Description | Mixed woodland to open woodland, with combinations of the species Lysiphyllum spp., Atalaya hemiglauca, Grevillea striata, Owenia acidula, Terminalia spp., Erythrophleum chlorostachys and Eucalyptus microneura. Corymbia polycarpa may occur as an emergent. Grass understorey is dominated by Aristida ingrata and Chrysopogon fallax. Aristida spp., Sarga plumosum, Panicum seminudum and Alloteropsis cimicina may also occur in the ground layer. Small patches of Acacia cambagei may occur. Occurs on gently undulating plains on Tertiary sands; light-textured brown sandy soils and red and yellow earths. Not a Wetland. (BVG1M: 27b). Vegetation communities in this regional ecosystem include: 2.5.1a: Mixed woodland, including combinations of the species Lysiphyllum cunninghamii, Atalaya hemiglauca, Eucalyptus microneura, Grevillea striata, Acacia spp. and Archidendropsis basaltica. Occasional canopy species include Terminalia spp., Erythrophleum chlorostachys and Melaleuca spp. A variable shrub layer, including Acacia spp., Eremophila mitchellii and Carissa lanceolata, may occur. The ground layer is tussock grasses, including Aristida spp., Enneapogon spp. and Eriachne spp. Occurs on gently undulating Tertiary sand sheets. Light-textured brown sandy soils and red and yellow earths. Not a Wetland. (BVG1M: 27b). 2.5.1b: Mixed low woodland to woodland, with combinations of the species Lysiphyllum cunninghamii, Terminalia spp., Erythrophleum chlorostachys, Melaleuca nervosa and Corymbia confertiflora. Atalaya hemiglauca, Acacia platycarpa, Ventilago viminalis and Grevillea parallela occasionally occur in the canopy. Eucalyptus microtheca may occur around the fringes. A shrub layer commonly occurs, including canopy species, Acacia spp. and Dodonaea physocarpa. The ground layer is tussock grasses, including Chrysopogon fallax and Aristida spp. Occurs on Quaternary residual sand sheets, commonly overlying Tertiary clay plains. Red to brown sands. Not a Wetland. (BVG1M: 27b). 2.5.1c: Lysiphyllum cunninghamii and/or Lysiphyllum carronii low woodland, commonly with Atalaya hemiglauca, Grevillea striata, Eucalyptus microneura, Erythrophleum chlorostachys, Terminalia aridicola subsp. aridicola, Archidendropsis basaltica and Ventilago viminalis. Acacia tephrina and A. cambagei may occasionally occur. A variable shrub layer may occur, including canopy species, Carissa lanceolata and Gardenia vilhelmii. The ground layer is tussock grasses. Occurs on Quaternary residual sand sheets, commonly overlying Cretaceous mudstones. Red sandy and earthy soils. Not a Wetland. (BVG1M: 27b). 2.5.1d: Atalaya hemiglauca and Lysiphyllum cunninghamii low open woodland, occasionally with Ficus opposita and Corymbia polycarpa. A shrub layer may occur, including canopy species, Acacia holosericea and Diospyros humilis. The ground layer is variable, with grasses and forbs, including Indigofera hirsuta, Aristida holathera and Bonamia media. Occurs on deep, re-worked sand deposits on Tertiary lateritic plateau surfaces. Brown loamy sands. Not a Wetland. (BVG1M: 27b). 2.5.1e: [RE not in use]²: This vegetation community is now mapped as 2.5.1c. Lysiphyllum cunninghamii and/or Lysiphyllum carronii low woodland, commonly with Atalaya hemiglauca, Grevillea striata, Eucalyptus microneura, Erythrophleum chlorostachys, Terminalia aridicola subsp. aridicola, Archidendropsis basaltica and Ventilago viminalis. Acacia tephrina and A. cambagei may occasionally occur. A variable shrub layer may occur, including canopy species, Carissa lanceolata and Gardenia vilhelmii. The ground layer is tussock grasses. Occurs on Quaternary residual sand sheets, commonly overlying Cretaceous mudstones. Red sandy and earthy soils. Not a Wetland. (BVG1M: 27b). |

| Fire management guidelines | SEASON: Commence burning early in dry season as soon as ground fuels can carry fire with fire extinguishing early evening. Continue to mid-dry season. INTENSITY: Low to moderate with occasional high intensity. INTERVAL: 1-5 years, but do not burn the same patches annually. Landscape mosaic should consist of patches with different times since burning. INTERVAL_MIN: 1. INTERVAL_MAX: 5. STRATEGY: Break up continuity of fuel across the landscape so that impact of late-season wildfire is minimised. Wildfire due to dry storms late in the dry season or in the early wet are natural occurrences, but they can burn over a wide area of the landscape with unwanted intensity and frequency. Use broad scale mosaic burning. ISSUES: Overabundant seedlings and saplings can lead to woody thickening if unchecked by fire. A long absence of fire or low intensity fire too early in the season may lead to overabundant seedlings and saplings. If ground fuels are sparse spell pastures prior to planned burns. Weeds such as buffel grass and rubbervine may be an issue for some tussock grass communities because weeds increase fuel loads leading to high intensity fires. |
| Comments | 2.5.1: Prone to scalding and wind erosion. Subject to clearing in east. 2.5.1c: A poorly surveyed vegetation community. Was previously mapped as 2.5.1e. 2.5.1d: A poorly surveyed vegetation community. 2.5.1e: A poorly surveyed vegetation community. |
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.
