|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Not a Wetland |
| Biodiversity status | No concern at present |
| Subregion | 9, 5 |
| Estimated extent1 | Pre-clearing 120000 ha; Remnant 2021 120000 ha |
| Short description | Eucalyptus similis and/or E. chartaboma +/- Erythrophleum chlorostachys, Corymbia spp. woodland on undulating Tertiary sand sheets, moderately high in the landscape |
| Structure code | Woodland |
| Description | Eucalyptus similis and/or Eucalyptus chartaboma woodland occasionally with Erythrophleum chlorostachys, Corymbia polycarpa and C. setosa. A lower tree or shrub layer may occur, including Grevillea glauca, Acacia spp., Petalostigma spp. and Alphitonia pomaderroides. The ground layer is tussock grasses, including Aristida spp., Heteropogon contortus and Schizachyrium fragile. Occurs on undulating Tertiary sand sheets, moderately high in the landscape, at the base of sandstone ranges. Red and yellow sands and earths. Not a Wetland. (BVG1M: 17c). |
| Protected areas | Rungulla RR |
| Special values | 2.5.20: Potential habitat for the near threatened species, Labichea brassii. |
| 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. |
