Regional ecosystem details for 10.4.7

Regional ecosystem 10.4.7
Vegetation Management Act class Of concern
Wetlands Palustrine
Biodiversity status Of concern
Subregion 2, 3
Estimated extent1 Pre-clearing 1000 ha; Remnant 2021 1000 ha
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 13.1 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.
