| Short description | Corymbia dallachiana and C. terminalis woodland to open woodland on old alluvial plains (western) |
| Structure code | Woodland |
| Description | Corymbia dallachiana and C. terminalis woodland, sometimes with C. plena. These Corymbia spp. and Grevillea parallela occasionally form a very sparse low tree layer. Mixed shrub layer including Carissa lanceolata, Acacia sericophylla, A. melleodora, Senna artemisioides, Petalostigma pubescens and Eremophila mitchellii. The ground layer is dominated by Triodia pungens and sometimes tussock grasses. Occurs on old alluvial sandplains with sandy yellow earth soils. Not a Wetland. (BVG1M: 18a). Vegetation communities in this regional ecosystem include: 10.3.10x1: Corymbia plena woodland with ground layer of Elionurus citreus and Aristida ingrata. Occurs on old dunes fringing lakes with sandy soil. Contains Palustrine. (BVG1M: 18a). 10.3.10x2: [RE not in use]²: This vegetation community is now mapped as 10.3.10. Corymbia dallachiana woodland with Eucalyptus brownii. Occurs on sandy terraces along Torrens Creek. Not a Wetland. (BVG1M: 18a). |

| Special values | 10.3.10: Habitat values for arboreal fauna possibly high. As for other riparian zones, this ecosystem has important values for stabilising stream banks and top soils, providing corridors for wildlife, and for trapping soil and maintaining water quality. |
| 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 | 10.3.10: Habitat values for arboreal fauna possibly high. Require further information. Occurs mostly in subregion 1 with some small areas in south-western parts of subregion 2 in the DEU. Potential for invasion by weed species. |
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.
