| Description | Eucalyptus crebra or Eucalyptus drepanophylla woodland, commonly with Corymbia brachycarpa and Corymbia dallachiana. Corymbia plena and Corymbia leichhardtii occasionally occur in the canopy. A secondary tree layer, dominated by canopy species and Acacia spp., usually occurs. A variable shrub layer usually occurs. Tussock grass ground layer, commonly with Triodia pungens. Occurs on sandy red and yellow earths on sand plains. Not a Wetland. (BVG1M: 18b). Vegetation communities in this regional ecosystem include: 10.5.4a: [RE not in use]²: This vegetation community is now mapped as 10.5.4. Eucalyptus crebra usually dominates often with Corymbia dallachiana in the very sparse canopy. Denhamia cunninghamii and Carissa lanceolata are often in the very sparse shrub layer. Chrysopogon fallax and Heteropogon contortus often dominate the very spare to spare ground layer. Occurs on sandplain. Not a Wetland. (BVG1M: 18b). 10.5.4b: [RE not in use]²: This vegetation community is now mapped as 10.5.4. Eucalyptus crebra dominates the very sparse canopy. Corymbia dallachiana is commonly present in the canopy. Petalostigma pubescens, Bursaria incana and Grevillea parallela are frequently present as small trees. Denhamia cunninghamii is present in the very sparse shrub layer. Chrysopogon fallax, Eriachne mucronata, Heteropogon contortus and Themeda triandra are commonly present and sometimes dominate the very sparse to mid-dense ground layer. Occurs on sandplain. Not a Wetland. (BVG1M: 18b). 10.5.4c: [RE not in use]²: This vegetation community is now mapped as 10.5.4. Eucalyptus crebra and Corymbia brachycarpa dominate the very sparse canopy. Corymbia dallachiana is occasionally present in the canopy. Grevillea parallela, Petalostigma pubescens and Acacia sericophylla frequently occur as scattered small trees. Acacia spp. And Jacksonia ramosissima dominate the very sparse to mid-dense shrub layer. Grewia savannicola is often present Triodia pungens usually dominates the very sparse to dense ground layer. Eriachne mucronata, Themeda triandra and Aristida spp. Sometimes occur as dominants or codominants. Occurs on sandplain. Not a Wetland. (BVG1M: 17c). 10.5.4d: Eucalyptus crebra woodland, commonly with Corymbia plena and Corymbia dallachiana. A secondary tree layer usually occurs, including canopy species and Acacia excelsa. A variable shrub layer usually occurs. Tussock grass ground layer including Heteropogon contortus, Chrysopogon fallax and Aristida spp. Occurs on sandy plains. Not a Wetland. (BVG1M: 18b). 10.5.4e: Eucalyptus crebra and Corymbia brachycarpa woodland, commonly with Corymbia dallachiana and/or Corymbia leichhardtii. A secondary tree layer commonly occurs, including Corymbia brachycarpa, Acacia excelsa, Petalostigma pubescens and Brachychiton populneus. A variable shrub layer usually occurs. Ground layer of Triodia pungens and tussock grasses including Themeda triandra, Chrysopogon fallax and Aristida spp. Occurs on sandy red and yellow earths. Not a Wetland. (BVG1M: 18b). 10.5.4f: Eucalyptus drepanophylla woodland, commonly with Corymbia dallachiana. Variable secondary tree and shrub layers usually occur. Tussock grass ground layer, commonly with Triodia pungens. Occurs on sandy red and yellow earths. Not a Wetland. (BVG1M: 18b). 10.5.4g: Eucalyptus drepanophylla woodland, commonly with Corymbia brachycarpa and/or Corymbia leichhardtii. Variable secondary tree and shrub layers usually occur. Ground layer of Triodia pungens and/or tussock grasses. Occurs on sandy red and yellow earths. Not a Wetland. (BVG1M: 18b). |

| Special values | 10.5.4: Eucalyptus tetrodonta occurs in this ecosystem near its southern limit in Queensland. |
| 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. |
| Comments | 10.5.4: Mainly subregion 3. Threatening processes include clearing for pasture development. Further survey is required to verify original and current extent of the component ecosystems of this regional ecosystem. 10.5.4a: Widespread common ecosystem. 10.5.4b: Two major areas in the north east of subregions 2 and 3. 10.5.4c: Only known from northern parts of the Desert Uplands. |
1 Estimated extent is from version 13.1 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.
