| Short description | Eucalyptus tectifica +/- Corymbia confertiflora woodland on old alluvial plains (recent Pleistocene surface) |
| Structure code | Woodland |
| Description | Eucalyptus tectifica woodland, occasionally with Corymbia confertiflora. A sparse shrub layer may occur, including Atalaya hemiglauca and Grevillea striata. The ground layer is tussock grasses, including Eulalia aurea, Chrysopogon fallax and Themeda triandra. Occurs on old alluvial plains (recent Pleistocene surface). Mainly solodised solonetz soils. Not a Wetland. (BVG1M: 18c). Vegetation communities in this regional ecosystem include: 2.3.19x1a: [RE not in use]²: This vegetation community has been amalgamated into 2.3.19. Eucalyptus tectifica woodland to open woodland, occasionally with Corymbia confertiflora, Erythrophleum chlorostachys and Lysiphyllum cunninghamii. A sparse shrub layer may occur. The ground layer is tussock grasses, commonly Eulalia aurea, Themeda triandra and Chrysopogon fallax. Occurs on old alluvial plains (recent Pleistocene surface). Silty clays and texture contrast soils. Not a Wetland. (BVG1M: 18c). 2.3.19x1b: [RE not in use]²: This vegetation community is now mapped as 2.3.70. Eucalyptus pruinosa subsp. pruinosa low woodland, commonly with Atalaya hemiglauca, Corymbia grandifolia subsp. grandifolia and Eucalyptus chlorophylla. Terminalia canescens, C. polycarpa and C. confertiflora may occur in the canopy. A sparse shrub layer may occur. The ground layer is tussock grasses, including Eulalia aurea and Chrysopogon fallax. Occurs on old alluvial plains (recent Pleistocene surface). Silty clays and texture contrast soils. Not a Wetland. (BVG1M: 18c). |

| Special values | 2.3.19: Restricted geomorphic surface. 2.3.19x1a: Restricted geomorphic surface. 2.3.19x1b: Restricted geomorphic surface. |
| Fire management guidelines | SEASON: Progressive early to mid-dry season, followed by storm time. Begin burning early in the fire season, with progressive patch fires burnt through the year. INTENSITY: Various. INTERVAL: 1-5 years. INTERVAL_MIN: 1. INTERVAL_MAX: 5. STRATEGY: Burn less than 30% in any year. No buffer necessary as this is a fire tolerant community. ISSUES: Maintaining a fire mosaic will ensure protection of animal habitats and mitigate against wildfires. |
| Comments | 2.3.19: This regional ecosystem poorly known. Survey required to verify extent and condition. Was previously mapped as 2.3.19x1a and 2.3.20t. Subject to high total grazing pressure leading to wind erosion and scalding. 2.3.19x1a: This regional ecosystem poorly known. Survey required to verify extent and condition. Subject to high total grazing pressure leading to wind erosion and scalding. 2.3.19x1b: This regional ecosystem poorly known. Survey required to verify extent and condition. Subject to high total grazing pressure leading to wind erosion and scalding. |
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.
