Description Open forest to woodland complex generally with a variety of stringybarks, grey gums, ironbarks and in some areas spotted gum. Canopy trees include Eucalyptus siderophloia, E. propinqua or E. major, E. acmenoides or E. portuensis, E. carnea and/or E. microcorys and/or Corymbia citriodora subsp. variegata. Other species that may be present locally include Corymbia intermedia, C. trachyphloia, Eucalyptus tereticornis, E. biturbinata, E. moluccana, E. longirostrata, E. fibrosa subsp. fibrosa and Angophora leiocarpa. Lophostemon confertus or Whipstick Lophostemon confertus often present in gullies and as a sub-canopy or understorey tree. Mixed understorey of grasses, shrubs and ferns. Hills and ranges of Cainozoic and Mesozoic sediments. Not a Wetland. (BVG1M: 9a).

Vegetation communities in this regional ecosystem include:
12.9-10.17a: Lophostemon confertus or L. suaveolens dominated open forest usually with emergent Eucalyptus and/or Corymbia species. Occurs in gullies and southern slopes on Cainozoic and Mesozoic sediments. Not a Wetland. (BVG1M: 28e).
12.9-10.17b: Corymbia citriodora subsp. variegata mixed open forest to woodland. Other commonly occurring canopy trees include Eucalyptus acmenoides, Angophora leiocarpa, E. siderophloia, E. carnea, E. longirostrata and C. intermedia. Other species that may be present locally include Eucalyptus tereticornis, E. crebra, E. fibrosa subsp. fibrosa and E. exserta. Lophostemon confertus (tree form and whipstick form) often present in gullies and as a sub-canopy or understorey tree. Mixed understorey of grasses and shrubs. Hills and ranges of Cainozoic and Mesozoic sediments usually with > 1000mm rainfall per annum. Not a Wetland. (BVG1M: 10b).
12.9-10.17c: Open forest of Eucalyptus carnea and/or E. tindaliae and/or E. helidonica +/- Corymbia citriodora subsp. variegata, Eucalyptus crebra, Eucalyptus major, Corymbia henryi, Angophora woodsiana, C. trachyphloia, E. siderophloia, E. microcorys, E. resinifera and E. propinqua. Lophostemon confertus often present as a sub-canopy or understorey tree. Occurs on Cainozoic and Mesozoic sediments. Not a Wetland. (BVG1M: 9g).
12.9-10.17d: Open forest generally containing Eucalyptus siderophloia, E. propinqua or E major, Corymbia intermedia. Other characteristic species include Lophostemon confertus, Eucalyptus microcorys and E. acmenoides or E. portuensis. Other species that may be present locally include Corymbia trachyphloia subsp. trachyphloia, C. citriodora subsp. variegata, E. longirostrata, E. carnea, E. moluccana and occasional vine forest species. Hills and ranges on Cainozoic and Mesozoic sediments. Not a Wetland. (BVG1M: 9a).
12.9-10.17e: Eucalyptus acmenoides, E. propinqua, Corymbia intermedia +/- E. microcorys, Lophostemon confertus open forest. Mixed understorey of grasses, shrubs and ferns. Hills and ranges of Cainozoic and Mesozoic sediments. Not a Wetland. (BVG1M: 9a).

Fire management guidelines SEASON: Summer to winter. INTENSITY: Plan for low to moderate. Unplanned occasional high intensity wildfire will occur. b: Low to moderate. INTERVAL: 4-8 years maintains a healthy grassy system. 8-20 years for shrubby elements of understorey. b: 4-25 years. INTERVAL_MIN: 4. INTERVAL_MAX: 25. STRATEGY: Aim for 40-60% mosaic burn. Needs disturbance to maintain RE structure (eucalypt overstorey with open understorey of predominantly non-rainforest species). Any moist sclerophyll that is relatively open with a mixture of grasses and shrubs should be a priority for fire management to retain RE structure. Burn with soil moisture and with a spot ignition strategy so that a patchwork of burnt/unburnt country is achieved. Variability in season and fire intensity is important. ISSUES: Frequent fire is needed to maintain understorey integrity, keeping more mesic species low in the profile of the understorey so that other species can compete. The Bauple longterm fire study site has shown this RE resilient to frequent burning with a mix of intervals, including annual and infrequent burns. It is essential that wildfires are not the sole source of fire in this ecosystem. A follow-up burn soon after a high intensity wildfire can be considered to reduce germinating/resprouting mesic species. The RE occurs on shallow rocky soils, so there tends to be no moisture holding capacity. Control of weeds (e.g., Lantana camara, Ochna serrulata, Praxelis clematidea) might be required.
Comments 12.9-10.17: This RE is being remapped to the community level. 12.9-10.17b: Typically occurs in moister coastal environments and is more species rich than 12.9-10.2. 12.9-10.17e: Mostly found in south-western parts of the bioregion including Carneys Creek and sandstone hills flanking volcanic plugs south of Maroon Dam.
