| Regional ecosystem | 10.4.7 |
|---|---|
| Vegetation Management Act class | Of concern |

| Short description | Casuarina cristata woodland on Cainozoic lake beds |
| Structure code | Woodland |
| Description | Casuarina cristata woodland. Diplachne fusca and Eulalia aurea dominated ground layer. Occurs on gilgai microrelief plains of Cainozoic lake deposits. Cracking clay soils. Palustrine. (BVG1M: 25a). |
| Supplementary description | Lorimer (1998), Ql4a; Thompson and Turpin (in prep), M9 |
| Special values | 10.4.7: Wetlands associated with gilgais. |
| 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 | 10.4.7: Mainly subregion 2, in Lake Galilee area. 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 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.
