| Short description | Eucalyptus melanophloia low open woodland on ferricrete |
| Structure code | Low Open Woodland |
| Description | Eucalyptus melanophloia low open woodland. A shrub layer, dominated by Acacia spp., is usually present. Triodia pungens dominated ground layer with tussock grasses. Occurs on gently undulating terrain with shallow yellow earths on ferricrete. Not a Wetland. (BVG1M: 17b). Vegetation communities in this regional ecosystem include: 10.7.11a: [RE not in use]²: This vegetation community is now mapped as 10.7.11. Eucalyptus melanophloia dominates the very sparse low tree layer. Corymbia dallachiana is often present in the canopy. Acacia sericophylla is present in the small tree layer. Acacia tenuissima is often present as scattered shrubs or in the very sparse shrub layer. Triodia pungens usually dominates the very sparse to mid-dense ground layer. Occurs on ferricrete. Not a Wetland. (BVG1M: 17b). 10.7.11b: [RE not in use]²: This vegetation community is now mapped as 10.5.7ax1. Austrochloris dichanthioides dominates the sparse ground layer. Eucalyptus melanophloia and Corymbia terminalis occur as emergent trees. Occurs on gently undulating terrain with shallow yellow earths on ferricrete. 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. |
| Comments | 10.7.11: Widespread in eastern parts of the bioregion. 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. 10.7.11b: Occurs in mosaic with scalds. Rare regional ecosystem only known from near Dunrobin, north of Jericho. |
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.
