Associated species in the upper and shrub layers often include Banksia robur, Banksia spinulosa var. spinulosa, Acacia aulacocarpa, Eucalyptus exserta, Grevillea banksii, Gahnia sieberiana, Corymbia intermedia and Xanthorrhoea latifolia subsp. latifolia. The ground layer is sometimes the dominant layer, and is dominated by heath species. These often include Xanthorrhoea latifolia subsp. latifolia, Lepidosperma laterale, Caustis recurvata, Dampiera ferruginea, Acrotriche aggregata, Entolasia marginata, Gompholobium pinnatum, Mirbelia rubiifolia, Sprengelia sprengelioides, Persoonia virgata, Hibbertia vestita, Pseudanthus orientalis, Styphelia flexifolia, Lomandra confertifolia, Monotoca scoparia and Pimelea linifolia. Slopes, ridges and crests on rolling to steep mountains of foothills and uplands, on Mesozoic to Proterozoic igneous rocks. Geologies are mapped as RKvp (Peninsula Range Volcanics) and PKgb (Bayfield Granite). Early Cretaceous - Late Permian pyroclastic crystal tuff, rhyolite flows, agglomerate, leucocratic biotite granite and biotite-hornblende adamellite. Probably occurs on seepage areas or areas with impeded drainage. Not a Wetland. (BVG1M: 29b). |

| Fire management guidelines | INTERVAL: At least 15 years. INTERVAL_MIN: 15. INTERVAL_MAX: 100. ISSUES: 8.12.10a: A geographically restricted ecosystem which is poorly known. It is almost certain that some of this ecosystem will be burnt when fire is applied to adjacent areas. Any fire in this ecosystem should be carefully observed and post fire conditions and recovery carefully monitored. |
| Comments | 8.12.10a: Similar in landscape position to 8.12.10b, though 8.12.10a occurs on a harder, rockier substrate with little soil, whilst 8.12.10b has a better soil development and has more heath species which are probably present due to impeded drainage or seepage conditions. Distinguished from all other regional ecosystems by the low structure and occurrence on exposed mountain tops and hilltops, inland from islands and headlands. Occurs in subregions 2 and 3 at Mt Jukes north-east of Kuttabul, on peaks in Britton Range south of Crediton and east of Home Creek, Connors Range south-west of Carmila. Also occurs extensively on ranges in Subregion 4 within the Military Training area. Condition is good, though the vegetation is naturally exposed to extremes in temperature, strong winds and severe fires, which can dramatically change structure and sometimes species composition. 8.12.10b: Similar in landscape position to 8.12.10a, though 8.12.10a occurs on a harder, rockier substrate with little soil, whilst 8.12.10b has a better soil development and has more heath species which are probably present due to impeded drainage or seepage conditions. Distinguished from all other regional ecosystems by the low structure and occurrence on exposed mountain tops and hilltops, inland from islands and headlands. Restricted to subregion 4 in the Shoalwater Bay Military Training Area. Present in the Peninsula Range to the west of Island Head Creek and Coast Range north-west of Corio Bay. Condition is good, though the vegetation is naturally exposed to extremes in temperature, strong winds and severe fires, which can dramatically change structure and sometimes species composition. |
