| Short description | Eucalyptus microtheca woodland to low open woodland with Sarga spp. in seasonally flooded depressions on gleyed podsolics |
| Structure code | Woodland |
| Description | Eucalyptus microtheca woodland with Sarga spp. understorey. Sparse lower tree storey of Melaleuca leucadendra and Excoecaria parvifolia. Occurs on seasonally flooded depressions and lagoons on Tertiary and Quaternary alluvium; gleyed podsolics. Palustrine. (BVG1M: 34d). Vegetation communities in this regional ecosystem include: 2.3.15x1: [RE not in use]²: This regional ecosystem is now mapped as 2.3.49. Seasonal swamps including a combination of grasses, sedges and aquatic species. Chenopodium auricomum may occur as a shrub in patches. A fringe of Eucalyptus microtheca commonly occurs. Occurs on silty, Quaternary alluvial plains derived from coarse-grained parent material. Clay soils. Palustrine. (BVG1M: 34d). |

| Special values | 2.3.15: Provides seasonal wetland habitat for a flora and fauna. Important feeding sites for water birds. 2.3.15x1: 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. 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 | 2.3.15: Subject to degradation from high total grazing pressure, particularly in the dry season. 2.3.15x1: This regional ecosystem poorly known. More information on condition required to confirm conservation status. |
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.
