| Short description | Eucalyptus quadricostata and Corymbia brachycarpa and/or Corymbia leichhardtii woodland on sandy plateaus |
| Structure code | Woodland |
| Description | Eucalyptus quadricostata and Corymbia brachycarpa and/or Corymbia leichhardtii woodland to open forest and Corymbia brachycarpa open forest. A secondary tree layer usually occurs and is composed largely of canopy species. A variable shrub layer usually occurs. Tussock grass ground layer, commonly with Triodia bitextura. Occurs on red sandy soils on plateau surfaces in the White Mountains area mostly above 500m altitude. Not a Wetland. (BVG1M: 18a). Vegetation communities in this regional ecosystem include: 10.5.9a: [RE not in use]²: This vegetation community is now mapped as 10.5.9. Eucalyptus quadricostata usually with Corymbia brachycarpa and C. leichhardtii dominate the very sparse canopy. Corymbia brachycarpa and C. leichhardtii are usually present and occasionally codominant in the canopy. Acacia longispicata, E. quadricostata, Alphitonia excelsa, Petalostigma spp. And Persoonia falcata are usually present and sometimes dominant in the very sparse shrub layer. Chrysopogon fallax, Triodia bitextura, Themeda triandra and Cymbopogon bombycinus are frequently present and sometimes dominant graminoids in the sparse to dense ground layer. Occurs on sandy plateau. Not a Wetland. (BVG1M: 18a). 10.5.9b: [RE not in use]²: This vegetation community is now mapped as 10.5.9. Eucalyptus quadricostata and Corymbia erythrophloia dominate the very sparse canopy. C. dallachiana is occasionally present in the canopy. Bursaria incana often occurs as scattered small trees. Carissa lanceolata, Denhamia cunninghamii and Grewia savannicola are commonly present in the very sparse shrub layer. Bothriochloa ewartiana, Heteropogon contortus and Triodia pungens are frequently present and sometimes dominant graminoids in the very sparse to sparse ground layer. Occurs on sandy plateau. Not a Wetland. (BVG1M: 18a). 10.5.9c: Eucalyptus quadricostata and Corymbia brachycarpa woodland to open forest. A secondary tree layer is usually present and is composed of canopy species with Acacia spp., Bursaria incana and Lysicarpus angustifolius. A variable shrub layer usually occurs. Tussock grass ground layer, commonly with Triodia bitextura. Occurs on red sandy soils on plateau surfaces in the White Mountains area mostly above 500m altitude. Not a Wetland. (BVG1M: 18a). 10.5.9d: Eucalyptus quadricostata and Corymbia leichhardtii woodland to open forest. A secondary tree layer dominated by Corymbia setosa and Eucalyptus quadricostata is commonly present. A variable shrub layer usually occurs. Tussock grass ground layer, commonly with Triodia bitextura. Occurs on red sandy soils on plateau surfaces in the White Mountains area mostly above 500m altitude. Not a Wetland. (BVG1M: 18a). |

| 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 | 10.5.9: Occurs near the White Mountains. Threatened by inappropriate fire regimes and grazing pressure. 10.5.9a: A rare vegetation community only found in the far north of subregion 2. 10.5.9b: Rare vegetation community only known from the White Mountains National Park or nearby. 10.5.9c: Occurs near the White Mountains. Threatened by inappropriate fire regimes and grazing pressure. 10.5.9d: Occurs near the White Mountains. Threatened by inappropriate fire regimes and grazing pressure. |
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.
