Regional ecosystem details for 10.9.6
| Regional ecosystem | 10.9.6 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Not a Wetland |
| Biodiversity status | Of concern |
| Extent in reserves | This regional ecosystem is now mapped as 10.5.7x2. |
| Short description | Acacia cambagei low woodland to open woodland on Cretaceous sediments |
| Structure code | Low Woodland |
| Description | [RE not in use]²: This regional ecosystem is now mapped as 10.5.7x2. Acacia cambagei dominates the very sparse to sparse small tree layer. Carissa ovata is usually present in the very sparse shrub layer. Occurs on flat to undulating terrain with cracking clay soils with sand cover overlying Cretaceous sediments. Not a Wetland. (BVG1M: 26a). Vegetation communities in this regional ecosystem include: 10.9.6x1: [RE not in use]²: This regional ecosystem is now mapped as 10.5.7x2. A. cambagei dominates the sparse to mid-dense tree layer. Occurs on gentle slopes with clayey soils derived from Mesozoic sediments. Not a Wetland. (BVG1M: 26a). 10.9.6x2: [RE not in use]²: This regional ecosystem is now mapped as 10.5.7x2. Acacia cambagei dominates the very sparse small tree layer. The very sparse ground layer has variable species composition. Occurs on undulating terrain with shallow clayey soil usually with stone cover. Not a Wetland. (BVG1M: 26a). |

| Special values | 10.9.6: Potential habitat for NCA listed species: Solanum adoxum. |
| Fire management guidelines | SEASON: Wet to mid-dry season. Avoid late dry (August -September) as intensity will be too high (August -September). INTENSITY: Low. INTERVAL: 6-10 years, but will depend on seasonal conditions and grazing pressure. INTERVAL_MIN: 6. INTERVAL_MAX: 10. STRATEGY: Fire is not generally applied directly to acacia dominated communities, but to surrounding fire-adapted communities in order to create a landscape mosaic of burnt/unburnt areas to mitigate against wildfire. Ensure fires are patchy. ISSUES: Acacias are fire sensitive and may be killed by high intensity or too frequent fire. These communities generally have sparse ground layer. Will only burn following irregular high rainfall events. |
| Comments | 10.9.6: Areas mapped were previously classified as an outlier of the Mitchell Grass Downs (4.9.11). Restricted ecosystem located south of Barcaldine. The soils are highly dispersible and susceptible to sheet and rill erosion. Naturalised species associated with this regional ecosystem include *Cenchrus ciliaris, which may dominate the ground layer. Potential threats to this ecosystem are mainly from tree clearing, high susceptibility to salinity, weed infestation, over grazing and soil erosion. It is recommended that grazing be restricted to very short periods after the wet-season. The native pasture under the tree canopy in this regional ecosystem tends to have reasonable nutritive value but low bulk. |
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.
