| Short description | Eucalyptus chlorophylla +/- Melaleuca viridiflora low open woodland on Mitchell River floodplain |
| Structure code | Low Open Woodland |
| Description | [RE not in use]²: This regional ecosystem is now mapped as 3.3.16. Eucalyptus chlorophylla (shiny-leaved box) dominates the very sparse to sparse canopy (7-15m tall). E. microtheca (coolibah) are occasionally present in the canopy. Scattered Melaleuca stenostachya (fibre-barked teatree) and less frequently, Dolichandrone alternifolia (lemonwood) are sometimes present as low trees (4-8m tall). A shrub layer is rarely formed, but scattered D. heterophylla, Grevillea striata (beefwood) and Excoecaria parvifolia (gutta percha) shrubs up to 3m tall are frequently present. The ground layer is sparse and dominated by grasses and sedges. Sarga plumosum (plume sorghum) may dominate in some areas, while Aristida spp., Eriachne spp., Eragrostis spp. and Schizachyrium spp. form the majority of the ground layer biomass elsewhere. Occurs on floodplain. Not a Wetland. (BVG1M: 16c). |

| 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 | 3.3.45: Gulf Plains bioregion. Mainly floodplain of the Mitchell River. |
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2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use.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.
