| Structure code | Woodland |
| Description | Corymbia dallachiana and/or Corymbia plena woodland, commonly with Corymbia terminalis. A prominent secondary tree layer of Callitris glaucophylla occasionally occurs. A variable shrub layer usually occurs. Triodia pungens dominated ground layer with tussock grasses. Occurs on sandy soils throughout the bioregion. Not a Wetland. (BVG1M: 18a). Vegetation communities in this regional ecosystem include: 10.5.2a: Corymbia dallachiana and/or Corymbia plena woodland, commonly with Corymbia terminalis. A secondary tree layer usually occurs, including canopy species and Acacia sericophylla. A variable shrub layer usually occurs. Triodia pungens dominated ground layer with tussock grasses. Occurs on sandy soils throughout the bioregion. Not a Wetland. (BVG1M: 18a). 10.5.2ax1: [RE not in use]²: This regional ecosystem is now mapped as 10.5.11. Eucalyptus whitei usually dominates the very sparse tree layer with Corymbia terminalis often co-dominant and C. dallachiana commonly present. Carissa lanceolata occurs as scattered shrubs or is present in a very sparse shrub layer. The very sparse ground layer is usually dominated by Aristida pruinosa, Heteropogon contortus or Enneapogon polyphyllus. Occurs on sandy traces on the Prairie/Torrens Creeks Cainozoic clay plains. Not a Wetland. (BVG1M: 18a). 10.5.2b: [RE not in use]²: This vegetation community is now mapped as 10.5.2a. Corymbia dallachiana dominates the very sparse canopy. Melaleuca nervosa is present in the canopy and the shrub layer. There are usually scattered plants or clumps of Acacia cowleana present in a weakly defined very sparse small tree layer and in a very sparse shrub layer. Aristida ingrata dominates the very sparse ground layer with Heteropogon contortus and Chrysopogon fallax usually present and sometimes subdominant. Occurs sandplains (north western). Not a Wetland. (BVG1M: 18a). 10.5.2c: Corymbia plena woodland, commonly with Callitris glaucophylla. Prominent secondary tree layer of Callitris glaucophylla. A variable shrub layer usually occurs. Tussock grass ground layer, occasionally with Triodia spp. And Fimbristylis dichotoma. Occurs on patches of deeper sand. Not a Wetland. (BVG1M: 18a). |

| Protected areas | Moorrinya NP, Cudmore (Limited Depth) NP |
| Special values | 10.5.2: Potential habitat for NCA listed species: Ptilotus brachyanthus. 10.5.2a: Population of Acacia tetragonophylla known from only one record in the Desert Uplands is from this vegetation community near Barcaldine. |
| Fire management guidelines | SEASON: Wet to mid-dry season while soil retains moisture. INTENSITY: Low to occasional moderate. INTERVAL: Interval will depend on need for burning, seasonal conditions and grazing pressure. Approximately 5-10 years. Do not burn during drought years. Concentrate burning during wet years. INTERVAL_MIN: 5. INTERVAL_MAX: 10. STRATEGY: Patchy burns are preferred. Mosaic 50-80% of area targeted. Burn under conditions of good soil moisture and when plants are actively growing. Burns during dry periods may leave areas of soil exposed, leading to erosion. ISSUES: Grazing can impact heavily and combined with low rainfall fuel loads will be low making burning difficult. Can be advantageous to burn in year following good rains to manage currant bush and false sandalwood. Eucalypts such as E. dallachiana and E. coolabah germinate and recruit following rainfall; do not burn to thin as attrition will reduce density in drought years. |
| Comments | 10.5.2: Threatening processes include clearing for pasture development. 10.5.2a: Widespread common ecosystem. 10.5.2b: Restricted ecosystem known from north western parts of subregion 2. 10.5.2c: Rare community. |
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.
