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.
