Regional ecosystem details for 4.9.18
| Regional ecosystem | 4.9.18 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Not a Wetland |
| Biodiversity status | No concern at present |
| Subregion | 4, 5, (11.26), (6.6), (10.4) |
| Estimated extent1 | Pre-clearing 243000 ha; Remnant 2021 233000 ha |
| Short description | Archidendropsis basaltica and mixed species, including Ventilago viminalis, Corymbia terminalis, Lysiphyllum carronii on Cretaceous sediments |
| Structure code | Low Open Woodland |
| Description | Mixed low open woodland, including a combination of the species Archidendropsis basaltica, Corymbia terminalis, Lysiphyllum carronii, Ventilago viminalis, Atalaya hemiglauca and Eucalyptus melanophloia. Other canopy species include Acacia pendula, Eucalyptus populnea, A. tephrina, A. cambagei and A. harpophylla. Scattered low shrubs occur, but a well-defined low shrub layer is not developed. The ground layer is seasonally variable, and composed of grasses and forbs. Occurs on flat to gently undulating plains formed from fresh Cretaceous sediments. Associated soils are generally shallow to moderately deep grey and brown cracking clays and minor texture contrast soils. Ironstone and lime occur in the profile. Not a Wetland. (BVG1M: 27a). |
| Supplementary description | Turner et al. (1978) T1 (LU 9); Turner et al (1993) T3 (LU 51) |
| Special values | 4.9.18: Relatively high fauna and flora diversity compared to surrounding grassland. |
| Fire management guidelines | SEASON: During the wet season to early dry season while soil retains moisture. INTENSITY: Low to moderate. INTERVAL: Fire return interval flexible. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Mosaic burn less than 30% in any year. Interval will depend on need for burning, seasonal conditions and grazing pressure. ISSUES: Ground layer is typically sparse and seasonally variable. |
