| Short description | Eucalyptus similis +/- Corymbia erythrophloia open forest on remnant sandstone sheets overlying mountain ranges |
| Structure code | Open Forest |
| Description | Open forest of Eucalyptus similis (yellowjacket) +/- Corymbia spp. +/- E. crebra (narrow-leaved ironbark) +/- Acacia shirleyi (lancewood) +/- C. peltata (rustyjacket) +/- Callitris intratropica (cypress pine). Open woodlands dominated by Eucalyptus provecta occur in some areas. Occurs on terraces and edges of sandstone plateaus and on shallow Tertiary remnant soils overlying granite and rhyolite. Not a Wetland. (BVG1M: 17c). Vegetation communities in this regional ecosystem include: 9.10.5a: Open forest of Eucalyptus similis (yellowjacket) +/- Corymbia erythrophloia (red bloodwood) +/- E. crebra (sens. lat.) (narrow-leaved ironbark) +/- C. polycarpa (long-fruited bloodwood) +/- Acacia shirleyi (lancewood) +/- C. peltata (rustyjacket) +/- Callitris intratropica (cypress pine) +/- E. provecta +/- Corymbia serendipita +/- C. trachyphloia (brown bloodwood). The mid layer varies from absent to a mid-dense shrub layer including canopy species juveniles, Grevillea glauca (bushman's clothes peg) and Acacia spp. The mid-dense ground layer is dominated by Themeda triandra (kangaroo grass) and Capillipedium parviflorum. Small areas of Eucalyptus provecta +/- A. shirleyi +/- Callitris intratropica open woodland may occur in this regional ecosystem. Occurs on terraces and edges of sandstone plateaus and on shallow Tertiary remnant soils overlying granite and rhyolite. Not a Wetland. (BVG1M: 17c). 9.10.5b: Open woodland of Eucalyptus provecta +/- Acacia shirleyi (lancewood) +/- A. burdekensis +/- Corymbia pocillum. A low sub-canopy layer contains scattered canopy species, Gardenia vilhelmii (breadfruit) and Petalostigma banksii (smooth-leaved quinine). Scattered juvenile canopy species can be scattered in every open shrub layer. The ground layer is mid-dense and can include Fimbristylis spp., Schizachyrium spp. and Triodia spp. (spinifex). Occurs on terraces and edges of sandstone plateaus and on shallow Tertiary remnant soils overlying granite and rhyolite. Not a Wetland. (BVG1M: 19d). 9.10.5c: Open woodland to woodland of Eucalyptus granitica (granite ironbark), Corymbia peltata (rustyjacket) +/- E. similis (yellowjacket). The mid layer is an open shrubland to shrubland of Acacia julifera subsp. julifera with the ground layer a mid-dense grassland of Themeda triandra (kangaroo grass), Heteropogon contortus (black speargrass) and Aristida spp. Occurs on slopes above wetlands on the Newcastle Range plateau. Not a Wetland. (BVG1M: 17c). |

| 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. |
