| Short description | Eucalyptus tetrodonta, E. chartaboma, Erythrophleum chlorostachys, Corymbia pocillum in mixed woodlands on sand sheets on Mesozoic sandstone plateaus |
| Structure code | Woodland |
| Description | Mixed woodland, including combinations of the species Eucalyptus tetrodonta, E. chartaboma, Erythrophleum chlorostachys, Corymbia pocillum and Eucalyptus megasepala. Occasional canopy species include C. polycarpa and Canarium australianum. A lower tree or shrub layer may occur, including canopy species, Grevillea spp., Petalostigma spp. and Acacia spp. The ground layer is tussock grasses, including Schizachyrium fragile, Heteropogon spp. and Aristida spp. Occurs on sand sheets on Mesozoic sandstone plateaus. Red to brown sands and sandy loams. Not a Wetland. (BVG1M: 14a). Vegetation communities in this regional ecosystem include: 2.5.19a: Eucalyptus tetrodonta and Erythrophleum chlorostachys woodland commonly with Eucalyptus chartaboma. Occasional canopy species include Corymbia pocillum and C. polycarpa. A lower tree or shrub layer commonly occurs, including canopy species, Grevillea spp. and Petalostigma spp. The ground layer is tussock grasses, including Schizachyrium fragile, Heteropogon spp. and Aristida spp. Occurs on undulating sand sheets on Mesozoic sandstone plateaus. Red to brown sands and sandy loams. Not a Wetland. (BVG1M: 14a). 2.5.19b: Eucalyptus chartaboma and/or Corymbia pocillum woodland to open forest, occasionally with Eucalyptus tetrodonta and Erythrophleum chlorostachys. A lower tree or shrub layer may occur, including canopy species, Petalostigma spp. and Acacia spp. The ground layer is tussock grasses, including, Schizachyrium fragile and Aristida spp. Occurs on sand sheets on Mesozoic sandstone plateaus. Red to brown sands and sandy loams. Not a Wetland. (BVG1M: 14a). 2.5.19c: Eucalyptus megasepala and/or E. tetrodonta and Corymbia pocillum woodland, occasionally with Erythrophleum chlorostachys. A lower tree or shrub layer commonly occurs, including canopy species, Acacia spp., Petalostigma banksii and Bossiaea armitii. The ground layer is tussock grasses, including Schizachyrium fragile and Heteropogon spp. Occurs on shallow sand sheets around the margins of Mesozoic sandstone plateaus. Red to brown sands and sandy loams. Not a Wetland. (BVG1M: 14a). 2.5.19d: Mixed woodland, including combinations of the species Eucalyptus tetrodonta, Erythrophleum chlorostachys, Corymbia polycarpa, Corymbia pocillum and Canarium australianum. A lower tree layer may occur, including Adenanthera abrosperma, Erythroxylum ellipticum and Grevillea glauca. A sparse, variable shrub layer may occur. The ground layer is tussock grasses, including Aristida spp. and Schizachyrium fragile. Occurs on Tertiary sand sheets, overlying weathered plateau surfaces. Red to brown sands and sandy loams. Not a Wetland. (BVG1M: 14a). |

| 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. |
