| Short description | Corymbia setosa low open woodland to low woodland with variable shrub layer |
| Structure code | Low Woodland |
| Description | Corymbia setosa low open woodland to low woodland, occasionally with Acacia sericophylla, Melaleuca nervosa and Grevillea pteridifolia. Shrub layer is variable in density and species composition depending on fire history. Temporarily dominant species include Acacia spp., Petalostigma pubescens, Calytrix microcoma and Melaleuca nervosa. Triodia pungens dominated ground layer, with tussock grasses. Occurs on pale sandy soils. Not a Wetland. (BVG1M: 18a). Vegetation communities in this regional ecosystem include: 10.5.8a: [RE not in use]²: This vegetation community is now mapped as 10.5.8. Corymbia setosa dominate the very sparse canopy. Melaleuca nervosa and Grevillea pteridifolia are usually present but occasionally either can be codominants in the canopy. Comesperma pallidum and Jacksonia ramosissima are often present as scattered shrubs. Triodia pungens usually dominates the very sparse ground layer. Occurs on pale sandy soils. Not a Wetland. (BVG1M: 18a). 10.5.8b: [RE not in use]²: This vegetation community is now mapped as 10.5.8. Melaleuca nervosa dominates the very sparse canopy. Corymbia setosa is frequently present in the canopy. Acacia spp. Are often present as scattered shrubs. Triodia pungens is often present and sometimes dominates the very sparse to sparse ground layer. Occurs on sandplain. Not a Wetland. (BVG1M: 21a). |

| 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. |
| Comments | 10.5.8: The density and floristics of this community are extremely variable over time and depend on fire history. At some stages of the fire cycle the shrub layer can be more prominent than the tree layer. Threatened by inappropriate fire regimes. 10.5.8a: Grevillea juncifolia replaces G. pteridifolia as a dominant canopy species in some areas to the west of Lake Galilee. Widespread vegetation community usually occurring in small patches. 10.5.8b: Uncommon vegetation community and usually occurs in small patches. |
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.
