| Short description | Acacia aneura +/- Eucalyptus populnea, E. melanophloia open forest on undulating plains in the east |
| Structure code | Woodland |
| Description | Acacia aneura woodland to open forest. Scattered Eucalyptus spp. often occur in the canopy or as emergents. Shrubs are scarce but may include species such as Eremophila mitchellii, E. glabra and E. gilesii. The ground layer is dominated by perennial grasses including Thyridolepis mitchelliana, Amphipogon caricinus, Eragrostis eriopoda and Monachather paradoxus. Other grasses include Aristida calycina var. praealta, A. jerichoensis, Eragrostis lacunaria, Digitaria hystrichoides, D. brownii and Panicum effusum. A large number of forbs may occur, including Calotis cuneata, Cheilanthes sieberi, Euphorbia drummondii, Goodenia glabra, Sida fibulifera, Solanum ellipticum, Trachymene ochracea and Vellea glabrata. Occurs on the flat to gently undulating plains formed from superficial Quaternary deposits over the Tertiary land surface in the east of the bioregion. Associated soils are predominantly shallow to moderately deep loamy red earths with varying contents of fine gravel occurring in the subsoil and ironstone gravel and shot usually present on the surface. Not a Wetland. (BVG1M: 23a). |

| Special values | 6.5.1: Potential habitat for NCA listed species: Solanum unispinum. |
| 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 | 6.5.1: The vegetation structure of this regional ecosystem may overlap 6.5.2, although the latter is generally dominated by Eucalyptus spp. and has no gravel in the soil. This regional ecosystem is dominated by A. aneura woodland (10-14 m) while 6.5.13 is dominated by an A. aneura low woodland (8-10m), occurs on shallower soils and is generally restricted to subregion 4. Occurs east of the Warrego River (subregion 2 and 3). Extensively cleared. Remaining extent has highly modified structural and floristic composition. |
