| Short description | Corymbia plena and/or C. terminalis woodland with Corymbia dallachiana on sandy alluvium |
| Structure code | Open Woodland |
| Description | Corymbia plena and/or Corymbia terminalis woodland usually with Corymbia dallachiana dominate the sparse canopy. A lower tree layer is usually very sparse and includes canopy species, Petalostigma pubescens and Hakea spp. Tussock grass ground layer of Heteropogon contortus and Aristida spp. Occurs on sandy alluvial terraces. Not a Wetland. (BVG1M: 9e). Vegetation communities in this regional ecosystem include: 10.3.12a: Corymbia plena and Corymbia dallachiana woodland, occasionally with Eucalyptus platyphylla. A variable secondary tree layer is usually present. A variable shrub layer is usually present and commonly includes Carissa lanceolata, Petalostigma pubescens and Acacia spp. Tussock grass ground layer dominated by Aristida spp., Heteropogon contortus and Eragrostis spp. Triodia pungens is also commonly present. Occurs on sandy alluvium. Not a Wetland. (BVG1M: 18a). 10.3.12b: Corymbia terminalis woodland, usually with Corymbia dallachiana. A second tree layer of Acacia salicina and C. terminalis may occur. Enneapogon polyphyllus and Bothriochloa ewartiana are present in the ground layer. Occurs on sandy alluvium. Not a Wetland. (BVG1M: 18a). 10.3.12c: [RE not in use]²: This vegetation community is now mapped as 10.3.10x1. Corymbia plena woodland. C. plena dominates the mid-dense canopy. Occurs on old sand dunes adjacent to Webb Lake. Not a Wetland. (BVG1M: 18a). |

| Special values | 10.3.12: Habitat values for arboreal fauna is 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: Do not target for burning. INTENSITY: Do not target for burning. INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not target for burning. Most of the vegetation communities will be difficult to burn. Important habitat for wildlife. Most species are fire sensitive. Burning in adjacent fire adapted communities will reduce risk of wildfire incursion. Ensure fire encroachment is limited. Burns in adjacent vegetation, implemented in late wet to early dry season, may limit fire incursion into sensitive vegetation. ISSUES: Fire exclusion or very low fire frequency will help maintain habitat trees. Fire may occasionally trickle into these ecosystems when there is sufficient ground fuel, but intensity, frequency and extent should be kept low. |
| Comments | 10.3.12: Threatening processes include high total grazing pressure. Further information on condition required to confirm Biodiversity Status. 10.3.12b: Occurs as an outlier along the Flinders River. Naturalised species associated with this regional ecosystem include *Cenchrus ciliaris, which may dominate the ground layer. |
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.
