| Description | Araucaria cunninghamii is a common emergent from the general canopy layer. Canopy species include Falcataria toona, Ficus virens, Canarium australianum, Alstonia scholaris, Planchonella pohlmaniana, Cleistanthus dallachyanus and Backhousia citriodora. Common shrub or understorey species are Mackinlaya macrosciadea, Baloghia inophylla, Polyalthia nitidissima, Bosistoa medicinalis and Aglaia sapindina. The sparse ground layer includes species such as Scleria sphacelata and Adiantum hispidulum. Vines and epiphytes are common and include Microsorum punctatum, Cissus oblonga, Smilax australis and Pisonia aculeata. Eucalyptus moluccana often associated with lower slopes on sandy sites. Occurs on low hills, ranges and boulder strewn slopes formed from Mesozoic to Proterozoic igneous rocks including granite. Not a Wetland. (BVG1M: 7a). Vegetation communities in this regional ecosystem include: 11.12.4a: Semi-evergreen vine thicket with open patches of Acacia fasciculifera, Archidendropsis thozetiana, Pleiogynium timorense and various other species. Occurs on low hills, ranges and boulder strewn slopes formed from Mesozoic to Proterozoic igneous rocks including granite. Not a Wetland. (BVG1M: 7a). |

| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: This vegetation requires protection from wildfire. Protection primarily relies on broad-scale management of surrounding country with numerous small fires throughout the year so that wildfires will be very limited in extent. Maintenance of fire breaks may be appropriate on flat country, but natural features will be useful as breaks in 'wild' country. ISSUES: Fuel reduction in the surrounding vegetation under low fire danger conditions and/or revegetation of cleared areas reduce the risk of damaging wildfires. Maintain or re-establish native vegetation communities adjacent to this ecosystem. Grazing may be useful in managing fuel loads created by introduced grasses such as buffel. |
