| Short description | Corymbia leichhardtii and Eucalyptus cloeziana mixed woodland on igneous hills |
| Structure code | Woodland |
| Description | Mixed woodland to open forest of Corymbia leichhardtii (yellowjacket) and Eucalyptus cloeziana (Gympie messmate) +/- Eucalyptus spp. and Corymbia spp. as subdominants. The shrub layer is sparse to mid-dense with a shrubland of Acacia spp. sometimes occurring. The ground layer is grassy. Occurs on rocky hills to steep hills on igneous geologies. Not a Wetland. (BVG1M: 13a). Vegetation communities in this regional ecosystem include: 9.12.30a: Woodland to open forest of Corymbia leichhardtii (yellowjacket) and Eucalyptus cloeziana (Gympie messmate) +/- E. portuensis (white mahogany) +/- C. citriodora subsp. citriodora (lemon-scented gum) +/- E. cullenii (Cullen's ironbark) +/- Callitris intratropica (cypress pine). Some canopy species can occur as emergents. The sparse to mid-dense shrub layer is dominated by juvenile canopy species, Persoonia falcata, Grevillea glauca (bushman's clothes peg) and Allocasuarina inophloia (stringybark sheoak) and a lower shrub with Jacksonia thesioides and Xanthorrhoea johnsonii (grass-tree) can occur. The sparse to mid-dense ground layer is dominated by Themeda triandra (kangaroo grass). Rocky rhyolite hills to steep hills. Not a Wetland. (BVG1M: 13a). 9.12.30b: Shrubland of Acacia leptostachya (slender wattle) +/- A. umbellata +/- Callitris intratropica (cypress pine) emergents. There is no mid layer or ground layer. Occurs on shallow soils on rock pavements within 9.12.30a. Not a Wetland. (BVG1M: 24a). |
| Protected areas | Evelyn Creek CP, Baldy Mountain FR |
| Special values | 9.12.30: Habitat for the vulnerable species Homoranthus porteri. |
| 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. Callitris intratropica are fire sensitive. Protect from fires until plants old enough to replace seed pool. |
| Comments | 9.12.30: Occurs extensively near the Wet Tropics boundary in the central bioregion. Clearing is occurring in some vegetation communities within this regional ecosystem. 9.12.30a: In some areas this community is dominated by E. shirleyi and Allocasuarina inophloia. Occurs extensively near the Wet Tropics boundary in the central bioregion. 9.12.30b: Occurs extensively near the Wet Tropics boundary in the central bioregion. |
