| Short description | Eucalyptus leucophylla and Corymbia terminalis woodland in depressions on podsolic soils |
| Structure code | Woodland |
| Description | Eucalyptus leucophylla and Corymbia terminalis woodland with a sparse shrub layer and a variable ground cover. Occurs on alluvial plains and seasonally waterlogged depressions on Tertiary surfaces; yellow podsolics. Not a Wetland. (BVG1M: 19b). Vegetation communities in this regional ecosystem include: 2.3.27x1a: [RE not in use]²: This vegetation community has been amalgamated into 2.3.66. Eucalyptus microtheca and/or Melaleuca viridiflora low open woodland. A lower tree or shrub layer of M. viridiflora may occur. The ground layer is Pseudoraphis spinescens and/or Eleocharis sp. Occurs in seasonal swamps (wooded closed depressions) on broad, Tertiary lateritic surfaces. Possibly subject to seepage from ferricrete surface. Brown clay soils. Small areas of open water may occur. Palustrine. (BVG1M: 34d). 2.3.27x1b: [RE not in use]²: This vegetation community has been amalgamated into 2.3.66. Mixed woodland including combinations of the species Eucalyptus microtheca, E. camaldulensis, Corymbia bella and Melaleuca viridiflora. Cathormion umbellatum occasionally occurs. The ground layer includes Pseudoraphis spinescens and Panicum trachyrhachis. Occurs in seasonal swamps (wooded closed depressions) on old alluvial plains (recent Pleistocene surface). Brown silty clay soils. Areas of open water may occur. Palustrine. (BVG1M: 34d). 2.3.27x2: Eleocharis spp. sedgeland, commonly with a fringe of Melaleuca viridiflora. Occurs on Tertiary lateritic surfaces. Palustrine. (BVG1M: 34d). |

| Special values | 2.3.27x1a: Seasonal to permanent wetland. Important feeding and breeding sites for water birds. 2.3.27x1b: Seasonal wetland. Important feeding and moulting sites for water birds. |
| 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. x1a, x1b: Low to moderate. 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. x1a, x1b: Maintain mosaic of time since burnt and unburnt patches in surrounding fire-adapted landscape to mitigate impacts of unplanned fire. 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. x1a, x1b: These do not necessarily readily burn because ground fuels are sparse. Riparian areas contain important habitat for fauna. |
| Comments | 2.3.27x1a: Eleocharis spp. are commonly excavated by feral pigs. Subject to degradation from high total grazing pressure particuylarily during dry season. |
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.
