| Short description | Eucalyptus whitei and Corymbia dallachiana low open woodland to woodland on shallow soils with hardpan |
| Structure code | Open Woodland |
| Description | Eucalyptus whitei and/or Corymbia dallachiana low open woodland to woodland, occasionally with Corymbia terminalis. A secondary tree layer, dominated by canopy species, commonly occurs. A variable shrub layer usually occurs, including Carissa lanceolata, Acacia spp., Denhamia cunninghamii, Senna artemisioides and Eucalyptus whitei. The ground layer is dominated Triodia pungens and tussock grasses. Occurs on shallow soils with silcrete or ferricrete hardpan. Not a Wetland. (BVG1M: 17c). Vegetation communities in this regional ecosystem include: 10.7.1a: Eucalyptus whitei low open woodland to woodland, occasionally with Corymbia dallachiana and Acacia sericophylla. A secondary tree layer, dominated by Eucalyptus whitei, commonly occurs. A variable shrub layer, dominated by Carissa lanceolata and Acacia tenuissima, usually occurs. The ground layer is dominated Triodia pungens and tussock grasses. Occurs on shallow soils with silcrete or ferricrete hardpan. Not a Wetland. (BVG1M: 17c). 10.7.1b: Corymbia dallachiana open woodland, commonly with Eucalyptus whitei and Corymbia terminalis. A variable secondary tree layer commonly occurs, including Acacia sericophylla, Grevillea parallela, Hakea lorea and Petalostigma pubescens. A variable shrub layer usually occurs. Tussock grass ground layer, commonly with Triodia pungens. Occurs on shallow soils with silcrete or ferricrete hardpan. Not a Wetland. (BVG1M: 12a). 10.7.1bx1: [RE not in use]²: This vegetation community is now mapped as 10.7.1a. Acacia acradenia dominates the sparse shrub layer. Occurs on undulating terrain on silcrete. Not a Wetland. (BVG1M: 31b). 10.7.1c: [RE not in use]²: This vegetation community is now mapped as 10.7.13x1. Triodia pungens dominates the sparse ground layer. Acacia spp. occur as scattered emergent shrubs. Occurs on silcrete. Not a Wetland. (BVG1M: 33b). 10.7.1d: [RE not in use]²: This vegetation community is now mapped as 10.7.10. Corymbia setosa dominates the very sparse canopy. Acacia spp. Are usually present in a very sparse tall shrub layer. Acacia tenuissima and Jacksonia ramosissima are frequently present in the very sparse small shrub layer. Triodia pungens dominates the sparse ground layer. Occurs n Tertiary silcretes. Not a Wetland. (BVG1M: 12a). 10.7.1e: [RE not in use]²: This vegetation community is now mapped as 10.7.4a. Eucalyptus persistens dominates the very sparse canopy. Triodia pungens dominates the sparse ground layer. Occurs on low stony rises on silcrete. Not a Wetland. (BVG1M: 19d). 10.7.1f: Mostly bare rock occasionally with scattered emergent shrubs, trees or graminoids on undulating terrain on silcrete. Occurs mostly on the perimeters of silcrete plains. Not a Wetland. (BVG1M: 31b). |

| 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: Due to the typically sparse nature of the spinifex in these ecosystems, there is rarely enough fuel load to burn. 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: Spinifex responds to low intensity burning following the first summer rains. De-stock burnt spinifex areas for many months in good seasons or several growing seasons in a run of dry years. Due to the typically sparse nature of the spinifex in these ecosystems, there is rarely enough fuel load to burn. |
| Comments | 10.7.1: Mainly subregion 1. The soils are shallow with low water holding capacity and low fertility. The topsoil's are susceptible to compaction and sheet erosion. Plant growth is seasonal and pasture productivity is low. There are few palatable species and their cover is very sparse. Potential threats to this ecosystem are mainly from inappropriate fire regimes. 10.7.1b: Uncommon vegetation community requiring further botanical survey. 10.7.1d: Rare vegetation community requiring further survey. 10.7.1e: Restricted distribution in central part of subregion 1. Further survey required for comprehensive floristic description. |
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.
