| Short description | Corymbia setosa low open woodland with variable shrub layer on ferricrete |
| Structure code | Low Open Woodland |
| Description | Corymbia setosa low open woodland to low woodland, occasionally with Petalostigma spp. Other species may be present in the canopy including: Corymbia dallachiana, Corymbia blakei, Eucalyptus whitei, Acacia sericophylla, Melaleuca nervosa and Grevillea striata. The shrub layer is extremely variable in density and species compositon, depending on fire history. Acacia spp., particularly Acacia acradenia and Acacia leptostachya, usually predominate and at the peak of the cycle may briefly form the ecologically dominant layer. The ground layer is dominated by Triodia pungens and includes tussock grasses. Occurs on gently undulating terrain with shallow sandy soil on ferricrete on Tertiary plateaus. Not a Wetland. (BVG1M: 18a). Vegetation communities in this regional ecosystem include: 10.7.10a: [RE not in use]²: This vegetation community is now mapped as 10.7.1a. Eucalyptus whitei dominates the very sparse tree layer. Acacia sericophylla is occasionally present as a scattered small tree. Carissa lanceolata and Acacia tenuissima are often present as scattered shrubs or in the very sparse shrub layer. Triodia pungens is present and often dominates the very sparse ground layer. Occurs on ferricrete. Not a Wetland. (BVG1M: 17c). 10.7.10b: [RE not in use]²: This vegetation community is now mapped as 10.7.10. Corymbia setosa dominates the very sparse low tree layer. Petalostigma pubescens, Melaleuca nervosa, Persoonia falcata and Petalostigma banksii are often present in the tall shrub layer. Carissa lanceolata and Denhamia cunninghamii are often present as scattered shrubs or in the very sparse small shrub layer. Triodia pungens usually dominates the very sparse to sparse ground layer. Occurs on ferricrete. Not a Wetland. (BVG1M: 12a). 10.7.10c: [RE not in use]²: This vegetation community is now mapped as 10.7.10. Corymbia setosa dominates the very sparse low tree layer. Acacia acradenia is usually present in the very sparse shrub layer. Amphipogon sericeus dominates the very sparse to sparse ground layer. Occurs on gravelly ferricrete slopes. Not a Wetland. (BVG1M: 12a). |
| Protected areas | White Mountains NP, Cudmore RR, Moorrinya NP |
| Special values | 10.7.10: Potential habitat for NCA listed species: Myriophyllum artesium. |
| 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 | 10.7.10: In good condition. The soils are shallow with low water holding capacity and low fertility. Plant growth is seasonal and pasture productivity is low. There are few palatable species and their cover is sparse. Potential threats to this ecosystem are mainly from inappropriate fire regimes and cattle grazing. 10.7.10a: Common vegetation community in subregion 1. 10.7.10b: Common vegetation community in northern parts of subregion 1. 10.7.10c: Rare vegetation community only found in the south of subregion 1. |
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.
