Subregion 27, (26), (22), (31), (25)
Estimated extent1 Pre-clearing 76000 ha; Remnant 2021 71000 ha
Short description Corymbia bloxsomei +/- Callitris glaucophylla +/- Eucalyptus crebra +/- Angophora leiocarpa woodland on Cainozoic sand plains and/or remnant surfaces
Structure code Woodland
Description Corymbia bloxsomei or Angophora leiocarpa woodland, occasionally with Callitris glaucophylla and Eucalyptus crebra. There is typically a secondary tree layer dominated by Allocasuarina luehmannii and/or Callitris glaucophylla and a low shrub layer dominated by species from plant families such as Ericaceae and Mimosaceae. Occurs on deep Cainozoic sandplains/remnant surfaces. Not a Wetland. (BVG1M: 18a).
Special values 11.5.21: Habitat for threatened plant species Homoranthus decumbens. Habitat for localised Acacia johnsonii.
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. INTERVAL: 3-5 years. INTERVAL_MIN: 3. INTERVAL_MAX: 5. STRATEGY: Burn less than 30% in any year. Burn under conditions of good soil moisture and when plants are actively growing. ISSUES: Young cypress are killed by fire. Planned burns have traditionally been carried out in the winter dry season; further research required.
