| Short description | Melaleuca viridiflora +/- Xanthorrhoea johnsonii low woodland on fans and alluvial plains |
| Structure code | Low Woodland |
| Description | [RE not in use]²: This regional ecosystem is now mapped as 3.3.49. Melaleuca viridiflora (broad-leaved teatree) dominates the sparse canopy (7-9m tall). Grevillea glauca (bushman's clothes peg), Acacia flavescens (powderpuff wattle) and other low trees form minor components of the canopy. Scattered emergent A. brassii and A. flavescens (yellow wattle) trees (10-13m tall) are sometimes present. The sparse shrub layer (0.5-2m tall) is dominated by Xanthorrhoea johnsonii (grass tree). Asteromyrtus symphyocarpa (liniment tree) is often subdominant. The ground layer is short (0.2-0.4m tall) and mid-dense. It is dominated by Schoenus sparteus. Dapsilanthus ramosus, Ectrosia leporina (hare's foot grass) and Rhynchospora spp. may make up a significant proportion of the cover in the ground layer. Occurs on fans and alluvial plains. Not a Wetland. (BVG1M: 21a). Vegetation communities in this regional ecosystem include: 3.3.43x1: [RE not in use]²: This regional ecosystem is now mapped as 3.3.20. Melaleuca nervosa (woodland paperbark), Corymbia setosa (rough-leaved bloodwood) and Grevillea glauca (bushman's clothes peg) are usually codominant in the canopy (7-9m tall) and Eucalyptus tetrodonta (Darwin stringybark) and Corymbia clarksoniana (Clarkson's bloodwood) are common emergents (12-13m tall) trees. The shrub layer (0.5-4m tall) is dominated by Xanthorrhoea johnsonii (grass tree). The ground layer is usually sparse to mid-dense and dominated by grasses usually Schizachyrium spp. (fire grass), Sarga plumosum (plume sorghum), Panicum spp. (panic), Aristida spp. (three-awned speargrass), Eriachne spp. (wanderrie grass) and Thaumastochloa spp. Occurs on sandy alluvial plains. Not a Wetland. (BVG1M: 14b). |

| Fire management guidelines | SEASON: Early to mid-dry season, with occasional storm burn or late dry season burn of limited area. INTENSITY: High, but low to moderate are more likely during the early to mid-dry season. INTERVAL: 1-5 years. INTERVAL_MIN: 1. INTERVAL_MAX: 5. STRATEGY: A mosaic of early dry season fires will prevent extensive wildfires in the late dry season and preserve areas for later storm-burning. Storm time and late dry season burns are used to maintain suitable vegetation structure. Burn less than 30% in any year. ISSUES: Lack of fire or low intensity burns can lead to overabundant broad-leaved ti-tree. High intensity fires may be difficult to achieve because of low fuel availability and accumulation rates and typically moister conditions. Reduction in cattle grazing may be required to produce adequate fire intensity. High intensity fires around storm time will promote a better developed ground layer. Active burning early in the dry season creates a mosaic to minimise the spread of wildfire late in the dry season. Early burns will usually burn with low intensity and will not control broad-leaved ti-tree. |
| Comments | 3.3.43: Upper Archer and Wenlock river catchments. 3.3.43x1: Restricted to the east coast alluvial plains near Lakefield National Park. |
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.
