| Estimated extent1 | Pre-clearing 74000 ha; Remnant 2021 63000 ha |
| Short description | Shrubland on natural scalds on deeply weathered coarse-grained sedimentary rocks |
| Structure code | Shrubland |
| Description | Shrubland +/- emergent eucalypts. Characteristic genera include Calytrix spp., Hakea spp., Kunzea spp., Micromyrtus spp., Acacia spp., Melaleuca spp. and (in the ground layer) Triodia spp. Often scattered or fringing emergent tree species are present, including Eucalyptus exserta, E. panda, E. curtisii, Corymbia trachyphloia and Acacia blakei. Occurs on shallow soils often associated with natural scalds on Cainozoic lateritic duricrusts and sometimes lithosols derived from quartzose sandstone. Not a Wetland. (BVG1M: 29b). Vegetation communities in this regional ecosystem include: 11.7.5a: Shrublands. Occurs on lithosols derived from lateritic surfaces. Not a Wetland. (BVG1M: 29b). 11.7.5b: Acacia aprepta shrubland. Occurs on lithosols derived from lateritic surfaces. Not a Wetland. (BVG1M: 29b). |
| Supplementary description | Taylor and Grimshaw (1994-95), Chinchilla MU2D, MU15, MU16D, MU17C, MU17D |
| Protected areas | Wondul Range NP, Isla Gorge NP, Chesterton Range NP, Coolmunda CP, Gurgeena CP |
| Special values | 11.7.5: Habitat of threatened plant species including Eucalyptus broviniensis, Micromyrtus carinata, Micromyrtus patula, Acacia curranii, Calytrix gurulmundensis and Homoranthus decumbens. |
| 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: In National Parks this would typically burn every 6 years, which is probably too frequent. |
| Comments | 11.7.5: Edge of hard pans may be associated with soak with soft spongy soil and liverworts, mosses and sedges during wet periods. |
