Regional ecosystem details for 10.3.26
| Regional ecosystem | 10.3.26 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Not a Wetland |
| Biodiversity status | Endangered |
| Extent in reserves | This regional ecosystem is now mapped as 10.5.7. |
| Short description | Lysiphyllum carronii low open woodland on alluvial plains |
| Structure code | Low Open Woodland |
| Description | [RE not in use]²: This regional ecosystem is now mapped as 10.5.7. Lysiphyllum carronii dominates the very sparse canopy. Eremophila mitchellii is usually present or dominates the very sparse tall shrub to low tree layer. Enneapogon spp. sometimes dominate the very sparse ground layer. Occurs on flat terrain with sandy clay to clay soil on sandplain (Qs) or alluvial plains (Qa). Not a Wetland. (BVG1M: 27c). |

| 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 | 10.3.26: Occurs mostly along the western edge of the bioregion. Frequently occurs in small patches. Further survey desirable to study botanical variations over its range. Rare ecosystem with >70% pastures degraded; subject to high total grazing. The surface soils are susceptible to compaction, sheet erosion and salting even with light stocking. The very sparse native pasture is mostly annuals and should be maintained to assist infiltration and minimise evaporation and soil compaction. Transpiration from the tree and shrub cover needs to be sustained to can keep the water table low and encourage surface moisture to infiltrate and leach salts below the root zone of the ground layer species. Subject to widespread pasture degradation, and to clearing for pasture development. Naturalised species associated with this regional ecosystem include *Cenchrus ciliaris, which may dominate the ground layer. |
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.
