| Short description | Eucalyptus populnea, E. melanophloia, Callitris glaucophylla, Corymbia tessellaris in mixed woodlands on sandy plains derived from old levee deposits in the West Balonne Plains subregion |
| Structure code | Woodland |
| Description | Mixed woodland, with a combination of the species Eucalyptus populnea, E. melanophloia, Callitris glaucophylla, Corymbia tessellaris, C. clarksoniana and E. chloroclada. Allocasuarina luehmannii may also occur in the canopy. A lower tree layer may occur, including Acacia aneura and canopy species. A shrub layer may occur, including Eremophila spp., Geijera parviflora and Acacia spp. The ground layer is dominated by perennial grasses, including Aristida spp., and Chrysopogon fallax. Occurs on sandy plains derived from old levee deposits in the West Balonne Plains subregion. Red to brown sandy loams. Not a Wetland. (BVG1M: 17a). Vegetation communities in this regional ecosystem include: 6.5.17a: [RE not in use]²: This vegetation community is now mapped as 6.5.17. Eucalyptus melanophloia and Callitris glaucophylla woodland. Occurs on uniform sandy soils. Not a Wetland. (BVG1M: 17a). |

| Special values | 6.5.17: High fauna diversity particularly bird species. |
| Fire management guidelines | SEASON: Late wet/dry season when there is good soil moisture. Early storm season or after good spring rains. INTENSITY: Various. INTERVAL: 3-5 years. INTERVAL_MIN: 3. INTERVAL_MAX: 5. STRATEGY: Burn less than 30% in any year. Burn under conditions of good soil moisture and when plants are actively growing. ISSUES: Avoid fires at the hottest and/or driest time of the year, when the extent of fires cannot be controlled. Low intensity fires with good soil moisture will be useful in reducing fuel loads and fire spread in later fires. Moderate fires may assist in regeneration of hard-seeded spp. Brigalow is soft-seeded, so germination is not promoted by fire. Casuarina cristata is fire sensitive, although germination can be good in bare areas. Best protection from wildfires is probably the creation of a multi-aged mosaic and perimeter burning. Fire increases risk from invasion by buffel grass. These REs often make up shade lines in paddocks and are heavily grazed. |
| Comments | 6.5.17: Vegetation community 6.5.17a has been amalgamated into this regional ecosystem. Changed status to of concern due to clearing over the 2001-3 period. Extensively cleared. |
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.
