| Short description | Micromyrtus capricornia open shrubland on Cainozoic sand plains and/or remnant surfaces |
| Structure code | Open Shrubland |
| Description | Variable open shrubland of species including Acacia spp. (e.g. A. julifera subsp. curvinervia) Micromyrtus capricornia, Calytrix spp., Hakea spp. and Melaleuca spp. typically with an emergent tree/open woodland layer dominated by species such as Eucalyptus exserta, E. melanophloia, E. crebra, Corymbia trachyphloia, C. clarksoniana or Melaleuca nervosa. Often distinguished by prominent understorey of Micromyrtus capricornia to 1-2 m. Occurs on Cainozoic sandplains and remnant surfaces. Restricted in occurrence to intact lateritic surfaces, usually tertiary plateau margins or gently dissected residuals. Often associated with hard setting uniform or gradational loamy or clay loam surfaced brown earths over ferricrete or petroreticulite. Not a Wetland. (BVG1M: 29b). |

| Fire management guidelines | SEASON: Spring to summer after rain, with good soil moisture. INTENSITY: Moderate to high. INTERVAL: 6-15 years. INTERVAL_MIN: 6. INTERVAL_MAX: 15. STRATEGY: This RE will burn when ready with adjacent vegetation. Burn small patches where possible (most are naturally small). Burn when sufficient soil moisture and according to seasonal condition. ISSUES: This heathland requires long enough fire intervals to allow regrowth to a mature structure. Ensure mature shrubland structure persists for many years in between fire events. |
| Comments | 11.5.18: In some areas, this RE may be quarried for road gravels. Most common around Dysart, Middlemount, Comet; with minor occurrences east of Mount Coolon and south of Blackwater. |
