| Short description | Eucalyptus populnea, E. melanophloia +/- Callitris glaucophylla woodland on coarse-grained sedimentary rocks |
| Structure code | Woodland |
| Description | Eucalyptus populnea predominates forming a discontinuous canopy (13-18 m high). E. melanophloia is often present in the canopy, and occasionally E. chloroclada trees occur. Eucalyptus moluccana or E. microcarpa may dominate localised areas. Callitris glaucophylla forms a lower tree layer (10-13 m tall) of varying density. Allocasuarina luehmannii is prominent in this layer in places. A tall shrub layer is developed in some stands. Dense patches of low shrubs occur in some stands. The ground cover is usually sparse and dominated by the perennial grasses, Bothriochloa decipiens and Aristida spp. Occurs on undulating to rolling hills. The soils are predominantly deep texture contrast soils with sandy surface horizons (up to 70 cms deep), over strongly alkaline to acidic, yellow clayey subsoils. Not a Wetland. (BVG1M: 17a). Vegetation communities in this regional ecosystem include: 11.10.11a: Eucalyptus moluccana or E. microcarpa woodland. Occurs on undulating to rolling hills. The soils are predominantly deep texture contrast soils with sandy surface horizons (up to 70 cms deep), over strongly alkaline to acidic, yellow clayey subsoils. Not a Wetland. (BVG1M: 13d). |

| Protected areas | Chesterton Range NP, Carnarvon NP, Palmgrove NP (S) |
| Special values | 11.10.11: Potential habitat for NCA listed species: Bertya calycina, Lomandra teres. |
| 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. |
| Comments | 11.10.11: Density of Callitris glaucophylla varies from sparse to dense depending on fire frequency and other management factors. |
