Regional ecosystem details for 2.3.70

Regional ecosystem 2.3.70
Vegetation Management Act class Least concern
Wetlands Not a Wetland
Biodiversity status Of concern
Subregion 7, 2, (1.3)
Estimated extent1 Pre-clearing 16000 ha; Remnant 2021 15000 ha
Short description Eucalyptus pruinosa low woodland on old alluvial plains (recent Pleistocene surface)
Structure code Low Woodland
Description Eucalyptus pruinosa low woodland, occasionally with Atalaya hemiglauca. The ground layer is commonly dominated by Eulalia aurea. Occurs on old alluvial plains (recent Pleistocene surface). Brown clay loam soils. Not a Wetland. (BVG1M: 19c).
Supplementary description Christian et al. (1954), Keighran, Westmoreland
Special values 2.3.70: Restricted geomorphic surface.
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: 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 2.3.70: This regional ecosystem poorly known. Survey required to verify extent and condition. Was previously mapped as 2.3.19x1b and 2.3.20t. Subject to high total grazing pressure leading to wind erosion and scalding.

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.
