| Short description | Eucalyptus platyphylla woodland on igneous rocks |
| Structure code | Woodland |
| Description | Eucalyptus platyphylla, Corymbia dallachiana, C. tessellaris and E. drepanophylla woodland. Corymbia clarksoniana, Eucalyptus drepanophylla and E. platyphylla dominate the woodland canopy. Other species sometimes present are Corymbia erythrophloia, C. dallachiana, Eucalyptus tereticornis, E. exserta and C. tessellaris. On Mt Burrumbush, E. acmenoides is present. The shrub layer is sparse to moderately dense, and may include Acacia leptostachya, Planchonia careya, Flueggea virosa subsp. melanthesoides, Albizia procera, Larsenaikia ochreata, Dodonaea viscosa, Pandanus spiralis and Coelospermum reticulatum. The ground layer is dominated by grasses up to 2 metres high. Species include Heteropogon triticeus, Heteropogon contortus, Mnesithea rottboellioides, Themeda triandra and Sorghum nitidum. Other ground layer species include Chamaecrista absus var. absus, Cajanus reticulatus and Grewia savannicola. Occurs on lower slopes of Mesozoic to Proterozoic igneous rocks. Not a Wetland. (BVG1M: 9b). Vegetation communities in this regional ecosystem include: 11.12.9a: Woodland with Eucalyptus drepanophylla, Corymbia peltata +/- C. clarksoniana. Mid-stratum +/- Acacia flavescens. Occurs on lower slopes of Mesozoic to Proterozoic igneous rocks. Not a Wetland. (BVG1M: 13c). |

| Fire management guidelines | SEASON: Early dry season when there is good soil moisture, with some later fires in the early storm season or after good spring rains. INTENSITY: Various. INTERVAL: 5-10 years. INTERVAL_MIN: 5. INTERVAL_MAX: 10. STRATEGY: A predominance of early dry season fires is recommended, although there is value in occasional late dry season fires, or storm burns, over small areas. Burning should begin fairly soon after the wet season. Where possible, ignite initial fires from upper ridges to burn down. Multiple dates of ignition within the same forest area will produce a mosaic of burnt landscape. ISSUES: Avoid ignition such that fires burn from the bottom of hills upwards. Too frequent fires may eliminate fire-killed shrubs and small trees (such as Casuarinas). Once boundaries are secured with early fires, late dry season and storm-burning may provide the intensity required to enhance seed germination of many species, but restrict spread and allow the creation and maintenance of a multi-aged mosaic. Ensure moderate densities of mature casuarinas, cypress pine and wattles are maintained; ensure the persistence of large eucalypts. |
| Comments | 11.12.9: Naturalised species associated with this regional ecosystem include *Ageratum conyzoides subsp. conyzoides. 11.12.9a: Occurs in the Mt Norman area. |
