| Short description | Corymbia polycarpa and Melaleuca spp. woodland on sandy channels and levees |
| Structure code | Woodland |
| Description | Corymbia polycarpa and Melaleuca spp. frontage woodland +/- Eucalyptus microtheca on heavier soils of back plains. Eucalyptus camaldulensis and Pandanus spp. on levees. Eucalyptus microtheca +/- Excoecaria parvifolia on smaller channels. Occurs on channels, levees and plains associated with recent watercourses; alluvial soils, mainly sands and earths. Not a Wetland. (BVG1M: 16b). Vegetation communities in this regional ecosystem include: 2.3.22x1: [RE not in use]²: This regional ecosystem is now mapped as 2.3.40. Eucalyptus microtheca and/or E. microneura woodland and/or Lysiphyllum cunninghamii woodland, occasionally with Corymbia confertiflora, C. polycarpa, Grevillea striata and E. leptophleba. A lower tree or shrub layer may occur, including Hakea arborescens, Petalostigma banksii, Flueggea virosa and Carissa lanceolata. The ground layer is tussock grasses, including Aristida spp. and Heteropogon contortus. Occurs on Quaternary alluvial plains, commonly with braided channels. Brown sandy loam soils. Not a Wetland. (BVG1M: 16c). |

| Special values | 2.3.22: Seasonal refuge for fauna. |
| Fire management guidelines | SEASON: Commence 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: Grazing can reduce fuel loads, make burning difficult and give woody species a competitive advantage. |
| Comments | 2.3.22: Survey required to verify condition. Subject to heavy total grazing pressure and associated vegetation changes and erosion. 2.3.22x1: 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.
