| Regional ecosystem | 1.11.14 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Not a Wetland |
| Biodiversity status | Endangered |
| Subregion | 3 |
| Estimated extent1 | Pre-clearing 400 ha; Remnant 2021 400 ha |
| Short description | Acacia cambagei low open woodland on clay soils derived from metamorphic rocks |
| Structure code | Low Open Woodland |
| Description | Acacia cambagei low open woodland with ground layer including Astrebla spp. Occurs on minor areas of clay soils derived from basic metamorphic rocks. Not a Wetland. (BVG1M: 26a). |
| Fire management guidelines | SEASON: Storm season to early dry season. INTENSITY: Various. INTERVAL: >30 years. INTERVAL_MIN: 30. INTERVAL_MAX: 100. STRATEGY: Burn in association with surrounding country. Maintain mosaic burning in surrounding country to mitigate against spread of unplanned fire into acacia woodlands. ISSUES: Acacia communities need fire for recruitment but make sure they occur at long intervals. Acacia communities are sensitive to high frequency intense fires. Buffel grass invasion can increase the potential for frequent and damaging fires. Overgrazing can reduce fuel loads and give woody species a competitive advantage. |
| Comments | 1.11.14: This vegetation community was previously mapped as 1.11.3x3. Occurs in the south of the bioregion. Subject to very high grazing pressure because it occurs as small patches in broad infertile landscapes. |
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.
