| Description | Acacia shirleyi open forest to woodland. Occasional canopy species include Eucalyptus spp., Corymbia spp. and Melaleuca foliolosa. A variable shrub layer may occur. The ground layer is tussock grasses, including Schizachyrium fragile and Cleistochloa subjuncea. Occurs on breakaways and adjacent footslopes on silicified or lateritised Tertiary and Cretaceous mudstones; rock outcrop and skeletal soils. Not a Wetland. (BVG1M: 24a). Vegetation communities in this regional ecosystem include: 2.7.1x2a: [RE not in use]²: This vegetation community is now mapped as 2.7.16. Acacia meiosperma shrubland to open scrub, occasionally with Cochlospermum gregorii, Acacia shirleyi, Corymbia pocillum, Grevillea pteridifolia and Macropteranthes montana. A lower shrub layer, commonly Calytrix leptophylla and Micromyrtus forsteri may occur. The sparse ground layer commonly includes Triodia spp., Schizachyrium fragile and Aristida dominii. Occurs on breakaways and slopes of lateritised, Tertiary sandstone hills. Not a Wetland. (BVG1M: 24a). 2.7.1x2b: [RE not in use]²: This vegetation community is now mapped as 2.7.17. Micromyrtus forsteri and/or Calytrix leptophylla dwarf open shrubland to open shrubland. Emergent Acacia shirleyi, Corymbia serendipita and A. meiosperma commonly occur. The ground layer is sparse grasses and forbs and includes areas of bare rock. Commonly occurs on flat, open areas in dissected, lateritised Tertiary sandstone hills. Not a Wetland. (BVG1M: 24a). 2.7.1x2c: [RE not in use]²: This vegetation community is now mapped as 2.7.18. Bare rock or isolated individuals of Gardenia vilhelmii, Acacia meiosperma or Corymbia gilbertensis. Patches of Eriachne rara, Aristida dominii and Eragrostis sp. tussock grassland commonly occur. Occurs on flats of exposed, lateritised Tertiary sandstone, commonly adjacent to rivers. Not a Wetland. (BVG1M: 24a). 2.7.1x3a: [RE not in use]²: This vegetation community is now mapped as 2.7.8. Melaleuca citrolens low open woodland. A sparse shrub layer may occur, including Petalostigma pubescens, Carissa lanceolata, Acacia meiosperma and Calytrix leptophylla. The ground layer is commonly bare rock with sparse grasses, including Aristida spp., Schizachyrium fragile and Eriachne spp. Occurs on breakaways and outcrops of exposed ferricrete on erosional surfaces in Tertiary sand sheets. Not a Wetland. (BVG1M: 21b). 2.7.1x4: [RE not in use]²: This regional ecosystem is now mapped as 2.7.10. Melaleuca foliolosa tall shrubland to low open forest, commonly with Macropteranthes montana, Acacia shirleyi, Eucalyptus provecta and Corymbia gilbertensis. A shrub layer commonly occurs, including Melaleuca foliolosa, Memecylon pauciflorum, Acacia meiosperma, Bossiaea armitii and Larsenaikia ochreata. The sparse ground layer is tussock grasses and forbs. Occurs on low rises, breakaways and stripped surfaces on lateritised Cretaceous mudstones. Not a Wetland. (BVG1M: 21b). 2.7.1x5: [RE not in use]²: This regional ecosystem is now mapped as 2.7.11. Mixed woodland to shrubland, including combinations of the species Corymbia gilbertensis, Acacia meiosperma, Cochlospermum gregorii, Melaleuca viridiflora, A. leptostachya, Corymbia polycarpa, M. stenostachya, Petalostigma banksii, Gardenia vilhelmii, A. shirleyi, Bossiaea armitii, Brachychiton paradoxus, Macropteranthes montana. The ground layer is commonly Aristida dominii, Polycarpaea corymbosa and Rhynchospora pterochaeta. Small areas of grassland/herbland and bare rock occur. Occurs on crests and slopes of lateritised, Tertiary sandstone hills. Not a Wetland. (BVG1M: 12b). 2.7.1x6: [RE not in use]²: This regional ecosystem is now mapped as 2.7.19a. Triodia spp. hummock grassland, commonly with emergent Eucalyptus melanophloia, Melaleuca citrolens, Corymbia pocillum, M. stenostachya and Acacia meiosperma. Small areas of Eucalyptus melanophloia and/or Melaleuca citrolens low open woodland with Triodia spp. understorey occasionally occur. Occurs on crests and slopes of lateritised, Tertiary sandstone hills. Not a Wetland. (BVG1M: 33b). 2.7.1x7: Acacia shirleyi woodland, commonly with Corymbia pocillum. A shrub layer of Acacia meiosperma or Gardenia vilhelmii commonly occurs. The ground layer is short tussock grasses, including Schizachyrium fragile and Eriachne spp. Occurs on crests and slopes of lateritised, Tertiary sandstone hills. Not a Wetland. (BVG1M: 24a). |

| Fire management guidelines | SEASON: Avoid the hottest seasons. INTENSITY: Moderate to high. INTERVAL: >5 years. INTERVAL_MIN: 5. INTERVAL_MAX: 50. STRATEGY: Burn less than 10% in any year. Buffer as indicated by fuel build-up in surrounding vegetation. ISSUES: Patch burning reduces spread of wildfires, and ensures a variety of ages. Widespread and frequent fires may reduce the extent of this vegetation type. Avoid fires at the hottest time of the year, when extent of fires cannot be controlled. Low intensity fires will be useful in reducing fuel loads and fire spread in later fires. Moderate fires may assist in regeneration of hard-seeded spp. |

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.
