| Description | Eucalyptus crebra grassy woodland. Other species such as Corymbia erythrophloia, Eucalyptus exserta, E. tereticornis, C. tessellaris, C. citriodora subsp. variegata may be present in low densities or in patches. Mid-layer generally sparse but can include low trees such as Vachellia bidwillii, Alphitonia excelsa, Allocasuarina luehmannii and Petalostigma pubescens. Small areas of Callitris glaucophylla occur in central western parts of bioregion. Occurs on Mesozoic to Proterozoic igneous rocks. Not a Wetland. (BVG1M: 13c). |

| Special values | 12.12.7: Potential habitat for NCA listed species: Callitris baileyi, Cycas megacarpa. This ecosystem is known to provide suitable habitat for koalas (Phascolarctos cinereus). |
| Fire management guidelines | SEASON: Summer to late-autumn. INTENSITY: Low. INTERVAL: 3-6 years. INTERVAL_MIN: 3. INTERVAL_MAX: 6. STRATEGY: Aim to burn 40-60% of any given area. Spot ignition in cooler or moister periods encourages mosaics. Burn to produce fine scale mosaics of unburnt areas. ISSUES: This RE has a long history of management. |
| Comments | 12.12.7: Individual 1:100 000 map sheets have been used to define this unit and to separate it from woodland in which Eucalyptus melanophloia is also a major component. Less steep areas have been extensively cleared for pasture. |
