| Short description | Eucalyptus populnea, Acacia aneura and/or E. melanophloia woodland on Quaternary sediments |
| Structure code | Woodland |
| Description | Eucalyptus populnea and/or E. melanophloia woodland. Other canopy species include E. exserta and C. terminalis. A secondary tree layer commonly occurs, typically dominated by Acacia aneura. A. excelsa and Brachychiton populneus may occur in this layer. A shrub layer may occur, including Eremophila mitchellii and Geijera parviflora. The ground layer is typically perennial grasses, including Thyridolepis mitchelliana, Aristida spp., Amphipogon caricinus, Monachather paradoxus and Themeda triandra. Other species include Digitaria spp., Panicum effusum, Cheilanthes sieberi, Euphorbia drummondii, Goodenia glabra, Hibiscus sturtii and Sida spp. Occurs on flat to gently undulating plains formed from Quaternary deposits over the Tertiary land surface. The soils are predominantly shallow to moderately deep red earths with hard-setting surfaces. 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 | 6.5.2: There is a wide variation in structure of the Acacia aneura mid-layer associated with past management history and which merges into the eucalypt overstorey in some areas. This regional ecosystem grades into 6.5.1. The latter is generally dominated by A. aneura and occurs on soils with surface gravel, while this (6.5.2) regional ecosystem is dominated by eucalypt open woodland to woodland (50-75 trees /ha) stratum with an A. aneura sub canopy tree layer. Regional ecosystem 6.5.13 is also similar but dominated by an A. aneura low woodland to open woodland with scattered emergent eucalypts (25 sometimes up to 50 trees /ha). Clearing is occurring. |
