| Short description | Eucalyptus spp., Angophora spp., Callitris spp. woodland on alluvial plains |
| Structure code | Woodland |
| Description | Angophora floribunda, A. leiocarpa, Eucalyptus tereticornis and E. chloroclada woodland with a secondary tree layer dominated by Callitris glaucophylla or Allocasuarina luehmannii. A shrub layer may occur, including Xylomelum cunninghamianum, Acacia neriifolia, Callitris endlicheri, Acacia conferta, Jacksonia scoparia, Leptospermum polygalifolium, Styphelia mutica and Melaleuca thymifolia. Occurs on Cainozoic alluvial plains with sandy soils. Not a Wetland. (BVG1M: 18a). |

| Protected areas | Wondul Range NP, Bendidee NP |
| Special values | 11.3.14: Potential habitat for NCA listed species: Acacia handonis, Fimbristylis 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: Low to moderate. INTERVAL: 6-10 years. INTERVAL_MIN: 6. INTERVAL_MAX: 10. STRATEGY: Burn less than 10-30% in any year to achieve a mosaic. Burn under conditions of good soil moisture and when plants are actively growing. Protection relies on broad-scale management of surrounding country with numerous small fires throughout the year so that wildfires will be very limited in extent. ISSUES: Cypress is killed by fire and regenerates from canopy stored seed (obligate seeder). It reaches reproductive age at about 6 years. Fire frequency less than 6-8 years will reduce cypress, but long fire interval will lead to cypress dominance and eucalypt suppression. Fuel reduction burns will help restrict incursions by high intensity wildfires that kill cypress. Fire after good spring rain has the potential to burn severely if there is no follow-up rain and re-lights occur. |
| Comments | 11.3.14: The dominant Callitris species is Callitris glaucophylla x C. verrucosa previously known as C. preissii subsp. verrucosa (family pine). |
