Regional ecosystem details for 9.12.5
| Regional ecosystem | 9.12.5 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Not a Wetland |
| Biodiversity status | No concern at present |
| Subregion | 4, (10.3) |
| Estimated extent1 | Pre-clearing 91000 ha; Remnant 2021 91000 ha |
| Short description | Eucalyptus quadricostata +/- Corymbia peltata open woodland on igneous hills and steep hills |
| Structure code | Open Woodland |
| Description | Open woodland to woodland of Eucalyptus quadricostata (square-fruited bloodwood) +/- Corymbia peltata (rustyjacket) +/- C. erythrophloia (red bloodwood) +/- C. dallachiana (Dallachy's gum). There can be a sparse sub-canopy which can include Alphitonia excelsa (soapbush), Bursaria incana (prickly pine), Persoonia falcata and Grevillea spp. There is a sparse to open shrub layer containing Xanthorrhoea johnsonii (grasstree), Acacia leptostachya (slender wattle) and Denhamia cunninghamii (yellowberry bush). The ground layer is either grassy with Themeda triandra (kangaroo grass) and Heteropogon contortus (black speargrass) or dominated by Triodia spp. (spinifex). Occurs on gravelly shallow soils derived from acid igneous geologies on hills and mountains. Not a Wetland. (BVG1M: 13a). |
| Special values | 9.12.5: Potential habitat for NCA listed species: Aristida thompsonii, Borya inopinata, Kunzea calida. |
| Fire management guidelines | SEASON: Early dry season and storm time. Timing of early dry season burns will vary depending on seasonal conditions; it may sometimes commence as early as March. Avoid burning August-October when south-easterly winds are typically strongest. INTENSITY: Low, with occasional moderate or high. INTERVAL: 5-10 years. INTERVAL_MIN: 5. INTERVAL_MAX: 10. STRATEGY: Apply mosaic across the landscape at a range of frequencies to create varying stages of post-fire response. ISSUES: These ecosystems contain shrubs that germinate after fire. Seedlings typically take a number of years to mature. Avoid repeated fires at short intervals and high intensity burns of broad areas. Leave areas of long unburnt vegetation to maintain a diversity of habitat for wildlife. Shrub species diversity will decline if areas are left long unburnt. |
| Comments | 9.12.5: Occurrence is limited to the Lolworth Range in the in the south of the bioregion. |
