| Regional ecosystem | 9.11.10 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Not a Wetland |
| Biodiversity status | Of concern |
| Subregion | 6, (2), (3) |
| Estimated extent1 | Pre-clearing 34000 ha; Remnant 2021 34000 ha |
| Short description | Eucalyptus cloeziana, Corymbia citriodora subsp. citriodora, E. portuensis and E. cullenii mixed woodland on steep dissected hills on highly metalliferous metamorphic rocks |
| Structure code | Woodland |
| Description | Mixed woodland to open forest including combinations of the species Eucalyptus cloeziana (Gympie messmate), Corymbia citriodora subsp. citriodora (lemon-scented gum), C. leichhardtii (yellowjacket), E. portuensis (white mahogany), E. cullenii (Cullen's ironbark), E. atrata (Herberton ironbark), E. crebra (narrow-leaved ironbark) and C. clarksoniana (Clarkson's bloodwood) +/- Callitris intratropica (cypress pine). There can be an open sub-canopy of canopy species, Grevillea glauca (bushman's clothes peg) and Allocasuarina inophloia (stringybark sheoak). The shrub layer varies from scattered plants to mid-dense and can include juvenile canopy species, Grevillea spp., Acacia spp., Persoonia falcata, Melaleuca viridiflora (broad-leaved paperbark), Cycas platyphylla and Xanthorrhoea johnsonii (grass-tree). The grassy ground layer is mid-dense to dense and often dominated by Themeda triandra (kangaroo grass), Arundinella spp. and occasionally Triodia spp. (Spinifex). Occurs on steep dissected hills and flats on highly metalliferous metamorphic rocks, often with shallow soils. Not a Wetland. (BVG1M: 13a). |
| Special values | 9.11.10: Habitat for geographically restricted and vulnerable flora species including Goodenia stirlingii, Acacia purpureopetala, Grevillea glossadenia and Corymbia rhodops. |
| 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 | 9.11.10: Occurs predominantly in the Irvinebank area in the central bioregion. |
