Regional ecosystem details for 11.9.14
| Regional ecosystem | 11.9.14 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Not a Wetland |
| Biodiversity status | Endangered |
| Subregion | 29, (26) |
| Estimated extent1 | Pre-clearing 21000 ha; Remnant 2021 8000 ha |
| Short description | Lysiphyllum carronii, Atalaya hemiglauca +/- Eucalyptus melanophloia +/- Acacia excelsa open woodland |
| Structure code | Open Woodland |
| Description | Atalaya hemiglauca predominates and together with Lysiphyllum carronii, (which may be codominant), forms a distinct but discontinuous open woodland to scattered trees canopy. Scattered Acacia excelsa and Eucalyptus melanophloia, Acacia harpophylla (in places), Acacia victoriae (in places) and Eremophila mitchellii low trees may form part of the canopy. Shrubs are not frequently present. The ground cover is open to moderately dense, and dominated by perennial grasses and forbs. Occurs on the undulating margins, and crests and upper slopes of undulating plains form on fine grained sediments. The soils are usually deep, uniform, brown to grey-brown, cracking clays with strongly alkaline subsoil's. Not a Wetland. (BVG1M: 27a). |

| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. ISSUES: This RE is very diverse and sensitive to fire. Do not target for burning, although low intensity fire with good soil moisture may be appropriate. The ground layer of perennial grasses and forbs may become dense, however there is a need to protect the overstorey from high intensity fire. Grazing may be a possible management tool in some situations where exotic grasses increase fuel loads beyond the norm. |
| Comments | 11.9.14: Naturally restricted regional ecosystem confined to Surat and Roma area. Extensively cleared and cultivated. |
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.
