| Description | Eucalyptus microneura woodland to low open woodland. Occasional canopy species include Erythrophleum chlorostachys and Terminalia spp. The ground layer is dominated by Aristida spp. Occurs on plains and plateaus on earths, podzolics and skeletal soils. Not a Wetland. (BVG1M: 18d). Vegetation communities in this regional ecosystem include: 2.5.9x1: [RE not in use]²: This regional ecosystem is now mapped as 2.5.29. Acacia shirleyi woodland to open forest, occasionally with Eucalyptus similis, Corymbia polycarpa, C. gilbertensis, E. chartaboma and Adenanthera abrosperma. A sparse shrub layer may occur, including Acacia shirleyi, Petalostigma banksii and Denhamia cunninghamii. The ground layer is tussock grasses, including Aristida spp., Schizachyrium fragile and Thaumastochloa spp. Occurs on undulating Tertiary sand sheets. Red sands and earths. Not a Wetland. (BVG1M: 24a). 2.5.9x2a: [RE not in use]²: This vegetation community is now mapped as 2.5.18a. Corymbia setosa and/or Corymbia polycarpa low open woodland to woodland, commonly with Corymbia grandifolia subsp. grandifolia, Terminalia spp., Erythrophleum chlorostachys and Eucalyptus microneura. Melaleuca spp. and Brachychiton paradoxus occasionally occur in the canopy. A sparse shrub layer commonly occurs, including Grevillea spp., Petalostigma banksii, canopy trees and Acacia spp. The ground layer is tussock grasses, dominated by Aristida spp. Occurs on broad, gently undulating, Tertiary sand sheets. Brown sands and sandy loams. Not a Wetland. (BVG1M: 18a). 2.5.9x2b: [RE not in use]²: This vegetation community is now mapped as 2.5.18b. Corymbia setosa, Melaleuca nervosa and C. polycarpa open woodland to woodland, commonly with Erythrophleum chlorostachys, C. pocillum and Eucalyptus tetrodonta. Grevillea glauca and Petalostigma pubescens occasionally occur in the canopy. A sparse shrub layer may occur, including canopy species, Asteromyrtus symphyocarpa and Alphitonia pomaderroides. The ground layer is tussock grasses, including Schizachyrium fragile, Aristida hygrometrica and Chrysopogon sp. Occurs on undulating, dissected, Tertiary sand sheets. Brown sandy loam soils. Not a Wetland. (BVG1M: 18a). 2.5.9x2c: [RE not in use]²: This vegetation community has been amalgamated into 2.5.9. Acacia torulosa and/or A. julifera subsp. gilbertensis tall shrubland, occasionally with Petalostigma banksii. Emergent Corymbia setosa, Eucalyptus microneura, Corymbia grandifolia subsp. grandifolia, Erythrophleum chlorostachys and Brachychiton paradoxus may occur. The ground layer is tussock grasses, commonly Aristida spp. Occurs on gently undulating, Tertiary sand sheets. Brown sandy loam soils. Not a Wetland.

Corymbia polycarpa woodland, commonly with Corymbia grandifolia subsp. grandifolia, C. confertiflora and Erythrophleum chlorostachys. Eucalyptus leptophleba and Brachychiton paradoxus occasionally occur in the canopy. A secondary tree layer of Terminalia oblongata subsp. volucris may occur. The sparse shrub layer commonly occurs including Melaleuca spp., Acacia spp. and Petalostigma spp. Includes small areas of Melaleuca spp. woodland with emergent Corymbia spp. The ground layer is tussock grasses, dominated by Aristida spp. Occurs on abandoned levees on broad, gently undulating Tertiary sand sheets. Brown sands and sandy loams. Not a Wetland. (BVG1M: 16b). 2.5.9x2e: [RE not in use]²: This vegetation community is now mapped as 2.5.28b. Corymbia grandifolia subsp. grandifolia and/or C. polycarpa open woodland, occasionally with C. setosa. A secondary tree layer commonly occurs, including Melaleuca viridiflora, M. citrolens and Lysiphyllum cunninghamii. A shrub layer commonly occurs, dominated by Acacia spp. The ground layer includes Triodia spp., Aristida spp., and Eriachne sp. Occurs on sand sheets on Tertiary lateritic plateau surfaces.

| 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. |

1 Estimated extent is from version 13.1 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.
