| Short description | Eucalyptus similis open forest on red kandosols on Tertiary plateaus, mesas and tablelands |
| Structure code | Open Forest |
| Description | Open forest to woodland of Eucalyptus similis (yellowjacket) +/- Corymbia setosa (rough-leaved bloodwood) +/- E. crebra (narrow-leaved ironbark) +/- C. clarksoniana (Clarkson's bloodwood) +/- C. erythrophloia (red bloodwood) or open woodland of Eucalyptus provecta +/- Acacia shirleyi (lancewood) +/- A. burdekensis +/- Corymbia pocillum. Occurs on plains on Tertiary plateaus and mesas. Soils are generally red kandosols and may overlie lateritic surfaces on the plateaus. May also occur on thin sandsheets overlying granite or rhyolite. Not a Wetland. (BVG1M: 17c). Vegetation communities in this regional ecosystem include: 9.5.1a: Open forest to woodland of Eucalyptus similis (yellowjacket) +/- Corymbia setosa (rough-leaved bloodwood) +/- E. crebra (narrow-leaved ironbark) +/- C. clarksoniana (Clarkson's bloodwood) +/- C. erythrophloia (red bloodwood). C. setosa is sometimes a dominant. Other Eucalyptus spp. and Corymbia spp. occur occasionally. An open sub-canopy layer often occurs and can contain juvenile canopy species, Grevillea glauca (bushman's clothes peg), G. parallela (silver oak) and Melaleuca nervosa (woodland paperbark). The shrub layer is generally sparse and can include Petalostigma banksii (smooth-leaved quinine) and Acacia spp. (wattle). The ground cover is dense grassy and is dominated by Themeda triandra (kangaroo grass), Sarga plumosum (plume sorghum) and Heteropogon spp. (speargrasses). C. polycarpa occurs in the west. Occurs on plains on Tertiary plateaus and mesas. Soils are generally red kandosols and may overlie lateritic surfaces on the plateaus. May also occur on thin sandsheets overlying granite or rhyolite. Not a Wetland. (BVG1M: 17c). 9.5.1b: 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 shallow Tertiary remnant soils overlying granite and rhyolite. Not a Wetland. (BVG1M: 19d). |

| 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. INTENSITY: Low, with occasional moderate. INTERVAL: 2-5 year intervals with longer unburnt patches. Fuel loads tend to reach a maximum after 2-3 years. Ensure burn programs occur after big wet season as fuel loads will be higher than average. INTERVAL_MIN: 2. INTERVAL_MAX: 5. STRATEGY: Burn less than 40% across the landscape in any year. Burning through the early dry season will produce a network of burns that will contain later fires. Fires will only gain in intensity as the dry season progresses. Grass composition can be affected by timing and intensity of fire. Occasional moderate fire will help to reduce overabundant trees that could potentially suppress ground layer vegetation. ISSUES: Leave areas of long unburnt vegetation to maintain a diversity of habitat for wildlife. |
| Comments | 9.5.1: Occurs on the Newcastle Range and near Greenvale in the west and south of the bioregion. Restricted regional ecosystem in this bioregion. 9.5.1a: Occurs on the Newcastle Range and near Greenvale in the west and south of the bioregion. Restricted regional ecosystem in this bioregion. 9.5.1b: Occurs in the Newcastle Range in the west of the bioregion. |
