| Description | [RE not in use]²: This regional ecosystem is now mapped as 3.3.20. Corymbia clarksoniana (Clarkson's bloodwood) dominates the sparse canopy (8-18m tall). Melaleuca viridiflora (broad-leaved teatree) and Syzygium eucalyptoides subsp. eucalyptoides are subdominant trees. M. viridiflora occurs at high stem densities, particularly in the sparse sub-canopy, (6-7m tall) where it is usually dominant. Corymbia polycarpa (long-fruited bloodwood) was recorded at one site. Banksia dentata (banksia), Asteromyrtus symphyocarpa (lineament tree) and Neofabricia mjoebergii (yellow teatree) are characteristic species of the sparse shrub layer (0.2-6m tall). The ground layer is mid-dense and dominated by Schoenus sparteus, Fimbristylis spp., Scleria spp., Eriocaulon spp. and Cartonema parviflorum. Lower slopes of sandridges and in drainage depressions. Not a Wetland. (BVG1M: 9e). |

| Fire management guidelines | SEASON: Commence planned burns early in the dry season, after the wet season when dry enough to burn. Use occasional storm burns but generally avoid periods of extremely hot, dry conditions. INTENSITY: Low to moderate with occasional high during storm burns. INTERVAL: 1-3 years. INTERVAL_MIN: 1. INTERVAL_MAX: 3. STRATEGY: Apply a mosaic across the landscape at a range of intervals to create varying stages of post-fire response. Burn 30-60% at the property level. ISSUES: To mitigate against the impact of late dry season fires, commence burning early in the season and continue through the dry to break up continuity of fuels across the landscape. These communities require particular management attention due to issues of grazing, weed invasion, rapid fuel accumulation, poor access and woody thickening. Fuel can reach maximum accumulation in 2 years. |

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2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use.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.
