| Short description | Corymbia spp., Lysicarpus angustifolius, Eucalyptus crebra, E. cloeziana open woodland on igneous rocks (granite) |
| Structure code | Open Woodland |
| Description | Corymbia watsoniana, Lysicarpus angustifolius, C. trachyphloia, Eucalyptus crebra and E. cloeziana mixed shrubby open woodland. Other canopy species may be present including Eucalyptus tenuipes, E. dura, Corymbia citriodora, Angophora leiocarpa, E. fibrosa subsp. nubilis and E. apothalassica. There is usually a low tree or shrub layer of species including Acacia spp., Callitris endlicheri, Grevillea whiteana, Petalostigma pubescens, Alphitonia excelsa and Allocasuarina inophloia. Occurs on hills formed from Mesozoic to Proterozoic igneous rocks. May include areas that occur on deeply weathered granite (land zone 5 or 7). Not a Wetland. (BVG1M: 9h). Vegetation communities in this regional ecosystem include: 11.12.5a: [RE not in use]²: This vegetation community is now mapped as Regional Ecosystem 11.12.5. Corymbia watsoniana, Lysicarpus angustifolius, C. trachyphloia, Eucalyptus crebra and E. cloeziana mixed shrubby open woodland. Other canopy species may be present including Eucalyptus tenuipes, E. dura, Corymbia citriodora, Angophora leiocarpa, E. fibrosa subsp. nubilis and E. apothalassica. There is usually a low tree or shrub layer of species including Acacia spp., Callitris endlicheri, Grevillea whiteana, Petalostigma pubescens, Alphitonia excelsa and Allocasuarina inophloia. Occurs on igneous rocks (granite). Not a Wetland. (BVG1M: 20a). |

| Special values | 11.12.5: Potential habitat for NCA listed species: Acacia handonis, Macrozamia crassifolia, Solanum sporadotrichum. |
| Fire management guidelines | SEASON: Late wet to early dry season when there is good soil moisture. Early storm season or after good spring rains. INTENSITY: Various. INTERVAL: 6-15 years. INTERVAL_MIN: 6. INTERVAL_MAX: 15. STRATEGY: Burn less than 30% in any year. Burn under conditions of good soil moisture and when plants are actively growing. All shrubby areas will carry fire after a good season. ISSUES: Management of this fire tolerant vegetation type should be based on maintaining vegetation composition, structural diversity, animal habitats and preventing extensive wildfire. Maintaining a fire mosaic will ensure protection of habitat and mitigate against wildfires. Requires a fire regime that maintains a diverse understorey. Planned burns have traditionally been carried out in the winter dry season; further research required. |
| Comments | 11.12.5: Regional Ecosystem 11.12.5a has been amalgamated into this RE. |
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.
