| Short description | Eucalyptus moluccana and/or E. microcarpa and/or E. woollsiana +/- E. crebra woodland on Cainozoic sand plains |
| Structure code | Woodland |
| Description | Eucalyptus moluccana or E. microcarpa or E. woollsiana woodland to open forest. Species such as Allocasuarina luehmannii and Callitris glaucophylla often form a secondary tree layer. Occurs on flat to gently undulating plains formed from Cainozoic/Quaternary sediments. Soils are mainly texture contrast with sandy surfaces. Not a Wetland. (BVG1M: 13d). |

| Protected areas | Lake Broadwater CP, Wondul Range NP, Beeron NP, Carnarvon NP, Humboldt NP |
| Special values | 11.5.20: Potential habitat for NCA listed species: Acacia handonis, Macrozamia machinii, Macrozamia platyrhachis. |
| 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: Various. INTERVAL: 6-15 years. INTERVAL_MIN: 6. INTERVAL_MAX: 15. STRATEGY: Burn less than 30% in any year. Burn under conditions of good soil moisture and when plants are actively growing. All shrubby areas will carry fire after a good season. ISSUES: Management of this fire tolerant vegetation type should be based on maintaining vegetation composition, structural diversity, animal habitats and preventing extensive wildfire. Maintaining a fire mosaic will ensure protection of habitat and mitigate against wildfires. Planned burns have traditionally been carried out in the winter dry season; further research required. |
