| Estimated extent1 | Pre-clearing 442000 ha; Remnant 2021 362000 ha |
| Short description | Corymbia citriodora or Eucalyptus crebra woodland on Cainozoic lateritic duricrust |
| Structure code | Woodland |
| Description | Corymbia citriodora and/or Eucalyptus crebra woodland. On adjacent footslopes, scattered E. crebra, C. clarksoniana and C. tessellaris may occur. There is usually a distinct tall shrub layer often dominated by Acacia spp. The ground layer varies from sparse to moderately dense and is dominated by perennial grasses. Occurs on Cainozoic lateritic duricrust. Not a Wetland. (BVG1M: 10a). |

| Protected areas | Beeron NP, Cania Gorge NP, Gurgeena CP |
| Special values | 11.7.6: Potential habitat for NCA listed species: Acacia calantha, Acacia handonis, Acacia rubricola, Boronia grimshawii, Eucalyptus taurina, Grevillea hockingsii, Macrozamia crassifolia, Melaleuca formosa, Rutidosis glandulosa, Zieria inexpectata, Zieria vagans. |
| 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 | 11.7.6: This regional ecosystem has been extensively logged which has resulted in a decrease in the number of trees in the larger size classes including many important habitat trees. |
