| Short description | Eucalyptus fibrosa subsp. nubilis +/- Corymbia spp. +/- Eucalyptus spp. woodland on Cainozoic lateritic duricrust |
| Structure code | Woodland |
| Description | Eucalyptus fibrosa subsp. nubilis predominates and forms a distinct but discontinuous open forest to woodland canopy (22-25m high). E. crebra often co dominates or be locally dominant, particularly on lower slopes. Also includes areas with Corymbia citriodora as a codominant. Other frequently occurring sub-dominant tree species include Corymbia trachyphloia, E. apothalassica, E. sideroxylon, Acacia shirleyi and Callitris glaucophylla. There is usually a low woodland mid layer dominated by Acacia spp. or sometimes Allocasuarina luehmannii and Callitris endlicheri. Scattered tall shrubs may occur, but rarely form a prominent layer. There is usually a moderately dense, low shrub layer developed with a variable floristic composition. The ground layer is open to moderately dense and dominated by grasses. Occurs on low hills and ranges formed from deeply weathered sediments. Soils are usually shallow (< 30cm deep) uniform sands with stone or rocks covering much of the ground surface. Not a Wetland. (BVG1M: 12a). |

| Fire management guidelines | SEASON: Late wet to early dry season when there is good soil moisture. Early storm season or after good spring rains. INTENSITY: Moderate to high. INTERVAL: 6-10 years. INTERVAL_MIN: 6. INTERVAL_MAX: 10. STRATEGY: Burn less than 10-30% in any year. Burn surrounding vegetation under conditions of good soil moisture and when plants are actively growing throughout the year so that wildfires will be very limited in extent. Fire exclusion not necessary. ISSUES: Best protection from wildfires is probably the creation of a multi-aged mosaic in surrounding vegetation and perimeter burning. Planned burns have traditionally been carried out in the winter dry season; further research required. |
| Comments | 11.7.7: Many areas have been subject to past logging causing a decreased proportion of trees in the larger size classes which includes many important habitat trees. |
