| Short description | Eucalyptus platyphylla, E. brassiana, Corymbia polycarpa and E. leptophleba in mixed open forests on active Quaternary alluvial plains in sandstone landscapes in the north-east |
| Structure code | Open Forest |
| Description | Mixed open forest to woodland, including combinations of the species Eucalyptus platyphylla, Eucalyptus brassiana, C. polycarpa and Eucalyptus leptophleba. Occasional canopy species include Corymbia tessellaris, C. confertiflora, Eucalyptus tetrodonta. A lower tree or shrub layer commonly occurs, including Melaleuca spp., Grevillea spp. and Planchonia careya. The ground layer is tussock grasses, including Heteropogon spp., Themeda spp. and Panicum spp. Occurs on active Quaternary alluvial plains in dissected sandstone landscapes in the north-east of the bioregion. Grey to brown sandy loam soils. Not a Wetland. (BVG1M: 16b). |
| Special values | 2.3.68: Supports locally uncommon plant species in the bioregion, including Eucalyptus brassiana and E. platyphylla. |
| 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 | 2.3.68: A rare vegetation community with limited extent. Was previously mapped as 2.3.23b. Occurs on Blackdown Stn and Torwood Stn. |
