| Short description | Eucalyptus populnea +/- Acacia aneura, E. melanophloia, E. intertexta woodland on sand sheets |
| Structure code | Woodland |
| Description | Eucalyptus populnea woodland, occasionally with E. melanophloia and E. intertexta. A secondary tree layer usually occurs, dominated by Acacia aneura. A shrub layer commonly occurs, including Eremophila gilesii subsp. gilesii, E. glabra, E. longifolia and Senna spp. The ground layer is variable, with tussock grasses and forbs, including Cheilanthes sieberi, Digitaria breviglumis, Aristida spp., Thyridolepis mitchelliana, Eragrostis eriopoda and Themeda triandra. A large number of forb species are frequent and seasonally abundant. Occurs on flat sand sheets formed from Quaternary deposits over the Tertiary land surface. Soils are moderately deep sands and loamy red earths. Not a Wetland. (BVG1M: 23a). |

| Fire management guidelines | SEASON: Various (wet season or winter). INTENSITY: Low to moderate. INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Aim to exclude fire by fuel reduction in adjacent vegetation communities where possible. Undertake partial burns when necessary to reduce fuel loads and protect against severe wildfire. Burn with high soil moisture (i.e., after rain/storms) or in winter. ISSUES: Acacia aneura may be killed by high intensity fire. There is rarely enough fuel load to burn in these ecosystems. |
| Comments | 6.5.7: Highly modified structural and floristic composition. Regional ecosystem 6.5.7 has larger number of Eucalyptus populnea trees (<100 ha) than 6.5.6 (scattered emergent). Occurs in two main areas; most extensively in areas east of the Warrego River around the Nebine Creek and also in areas around Adavale. |
