Short description Microphyll vine forest +/- Araucaria cunninghamii on old sedimentary rocks with varying degrees of metamorphism and folding
Structure category Dense
Description Microphyll rainforest (with or without Araucaria cunninghamii emergents) and semi-evergreen vine thicket. Floristics and structure varies with site. There is usually a continuous tree canopy (9 - 15m high) with a wide range of species including Flindersia australis, Backhousia kingii, Excoecaria dallachyana, Melia azedarach, Ficus spp., Strychnos psilosperma, Macropteranthes leichhardtii and Alstonia constricta. An emergent tree layer (12- 20m high) commonly occurs with species including Brachychiton australis, B. rupestris, Flindersia australis, Ficus spp. Araucaria cunninghamii and sometimes Eucalyptus spp. There is a shrub layer (1-3m high) with density depending on canopy cover and frequent species including Croton spp., Abutilon spp., Capparis spp. Acalypha eremorum and Codonocarpus attenuatus. Ferns, mosses and vines are common. Occurs on hilly terrain with slopes ranging from 55 and up to 80% locally. Formed from moderately to strongly deformed and metamorphosed sediments and interbedded volcanics. Associated soils are generally shallow loams and clays with minor areas of deeper cover.

Fire management guidelines 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.
Comments 11.11.5: In moist microhabitats such as sheltered gullies, rainforest tends to the notophyll type. The rainforest at higher altitude on topographic isolates such as Mount Aberdeen has close affinities with upland rainforest of Central Queensland Coast bioregion.
