| Short description | Eucalyptus platyphylla and/or Corymbia clarksoniana and/or C. intermedia and/or C. tessellaris woodland on low undulating areas on metamorphosed sediments |
| Structure code | Woodland |
| Description | Eucalyptus platyphylla and/or Corymbia clarksoniana and/or C. intermedia and/or C. tessellaris open woodland to open forest (9-25m tall). Associated canopy species may include E. drepanophylla, E. crebra, E. tereticornis and C. tessellaris. There is frequently a very sparse to mid-dense secondary tree layer/tall shrub layer, often dominated by Melaleuca viridiflora var. viridiflora and/or M. nervosa, or other species may include E. platyphylla, Allocasuarina torulosa and Lophostemon suaveolens. There is occasionally a very sparse shrub layer which may include Planchonia careya, Glochidion lobocarpum, Acacia holosericea and Acacia spp. The ground layer is often dominated by species such as Themeda triandra, Heteropogon triticeus, Xanthorrhoea latifolia subsp. latifolia and Imperata cylindrica. Occurs on gently undulating slopes (often adjacent to alluvial plains), on undulating to rolling low hills of lowlands and foothills, on metamorphosed sediments. Geologies mapped as Pc/s (Carmila beds/s), Pla (Carmila Beds), Pc/v (Carmila beds/v) and Ccs (Shoalwater Formation). Early Permian siltstone and mudstone, volcanilithic, lithic and quartzose sandstone, conglomerate and rhyolitic to dacitic volcaniclastic rocks. Not a Wetland. (BVG1M: 9b). |

| Special values | 8.11.4: Habitat for Black-chinned Honeyeater near Kinchant Dam. In subregions 4 and 5 this RE is habitat for the highly restricted plant species Bowenia serrulata, and for Macrozamia miquelii which occurs there at the northern end of its range. |
| Fire management guidelines | SEASON: Winter with occasional storm burns. INTENSITY: Moderate. INTERVAL: 4 - 6 years. INTERVAL_MIN: 4. INTERVAL_MAX: 6. STRATEGY: Aim to burn no more than 50 % of any given area. ISSUES: Fire may also be deleterious during app June to November as this period coincides with the expected peak flowering season of Eucalyptus drepanophylla which is used as a dietary resource by the black-chinned honey-eater. If patchy fires cannot be achieved in a given area during this time, storm burning is strongly recommended. |
| Comments | 8.11.4: Distinguished from 8.11.1 (which often has the same spp. dominance) by its association with very gently sloping terrain adjacent to alluvial areas (as opposed to definite hills). The RE 8.11.6 also often occurs on gently sloping terrain, however it is usually dominated by E. latisinensis (occasionally by E. crebra but then E. platyphylla is absent). The prominent presence of E. platyphylla and/or Corymbia clarksoniana and/or C. tessellaris are also a good indicator for this RE. Occurs in subregion 2 and 6, from near Ben Lomond, south to Bell Creek (10km north-west of Sarina). Also found in subregion 4, with an extensive area near Pineapple Gap, and other smaller areas scattered throughout the lowlands. Extensively cleared. Remnants in good condition are rare or non-existent in the northern subregions as they are heavily fragmented and disturbed. Some areas are heavily invaded by the woody weed *Haematoxylum campechianum. Continued clearing for subdivision and incremental loss through property development (fence lines, tracks, dams, buildings etc) are also a threat. Weeds are common and species include *Megathyrsus maximus, *Triumfetta rhomboidea, *Passiflora suberosa, *P. pallida, *Urena lobata and *Xanthium occidentale. |
