| Short description | Acacia cambagei woodland on Cainozoic lake beds (subregion 3) |
| Structure code | Open Forest |
| Description | [RE not in use]²: This regional ecosystem is now mapped as 10.4.5. Acacia cambagei open forest. The very sparse sub-canopy is dominated by A. cambagei. Small trees frequently present include Lysiphyllum carronii and Terminalia oblongata. A. cambagei, Alectryon diversifolius, Erythroxylon australe, Atalaya hemiglauca, Santalum lanceolatum, Carissa spp. And Capparis lasiantha are usually present in the very sparse shrub layer. The ground layer is usually very sparse. Occurs on plains and gently undulating downs with cracking grey clay soils on Cainozoic lake beds. Not a Wetland. (BVG1M: 26a). |

| 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: These communities generally have sparse ground layer. Will only burn following irregular high rainfall events. 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. |
| Comments | 10.4.4: Largely restricted to the vicinity of Natal Downs and Victoria Downs. This ecosystem is subject to clearing for pasture development. There is potential for Parthenium invasion on the heavy clay soils. |
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2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use.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.
