| 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 (13-22m tall). C. dallachiana (Dallachy's gum) is usually present as a subdominant canopy tree. Melaleuca nervosa (teatree) occasionally occurs in the canopy but is more common as a sub-canopy tree (5-12m tall). Other common sub-canopy trees are Piliostigma malabaricum (bauhinia), Lophostemon suaveolens (swamp mahogany) and Planchonia careya (cocky apple). Antidesma ghaesembilla (black currant) and Corymbia clarksoniana with Azanza thespesioides consistently form a sparse shrub layer (0.3-3m tall. The ground layer is sparse and dominated by Ischaemum spp., Eragrostis spp. (love grass), Arundinella setosa (reed grass) and Fimbristylis spp. Occurs on floodplains. 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. |
| Comments | 3.3.19: Characterised by the frequent occurrence of Piliostigma malabaricum in the sub canopy. West flowing rivers in the central bioregion. |
1 Estimated extent is from version 13 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2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use.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.
