| Structure code | Closed Forest |
| Description | Complex to simple notophyll vine forest. Waterhousea floribunda is predominant fringing stream channels. Other species can include Cryptocarya hypospodia, C. obovata, C. triplinervis, Argyrodendron trifoliolatum, Ficus coronata, F. fraseri, F. macrophylla forma macrophylla, Aphananthe philippinensis, Elaeocarpus grandis, Grevillea robusta, Castanospermum australe and Syzygium francisii. Ficus racemosa and Nauclea orientalis in north of bioregion. Eucalyptus spp. emergents (e.g. E. grandis) and Araucaria cunninghamii; less commonly Agathis robusta may also be present. Occurs on Quaternary alluvial plains and channels. Riverine. (BVG1M: 4b). Vegetation communities in this regional ecosystem include: 12.3.1a: Complex notophyll vine forest. Typical canopy species include Castanospermum australe, Elaeocarpus grandis, Grevillea robusta, Cryptocarya obovata, Beilschmiedia obtusifolia, Dysoxylum mollissimum subsp. molle, Pseudoweinmannia lachnocarpa, Argyrodendron trifoliolatum, Planchonella australis, Ficus watkinsiana, F. macrophylla forma macrophylla, Aphananthe philippinensis, Toona ciliata and Syzygium francisii. Emergent Eucalyptus grandis or Lophostemon confertus may occur. Waterhousea floribunda and Tristaniopsis laurina may occur on banks of stream channels. Typical sub canopy species include Cryptocarya triplinervis, Archontophoenix cunninghamiana, Endiandra pubens, Arytera divaricata, Syzygium moorei and Macadamia spp. Occurs on Quaternary alluvial plains and channels in areas of high rainfall (generally >1300mm). Riverine. (BVG1M: 4b). |

| Special values | 12.3.1: Habitat for threatened plant species including Xanthostemon oppositifolius, Fontainea rostrata, Macadamia integrifolia and M. ternifolia. Habitat for threatened fauna species including Cyclopsitta diophthalma coxeni and Ornithoptera richmondia. Important for fruit-eating birds, many of which migrate seasonally from upland to lowland rainforest. 12.3.1a: Habitat for threatened plant species including Xanthostemon oppositifolius, Fontainea rostrata, Macadamia integrifolia and M. ternifolia. Habitat for threatened fauna species including Cyclopsitta diophthalma coxeni and Ornithoptera richmondia. Important for fruit-eating birds, many of which migrate seasonally from upland to lowland rainforest. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately. Protection relies on broad-scale management of surrounding country. May need active protection from wildfire in extreme conditions or after prolonged drought. Planned burns should not create a running fire into vine forest. Ensuring conditions of good soil moisture and moisture of litter in surrounding communities will limit fire behaviour/intensity. ISSUES: Fire sensitive and not normally flammable. There may be issues with lantana and other weeds from fire and other disturbance. Remnants may be limited by frequent fire at the margins. |
| Comments | 12.3.1: This RE has been split into 12.3.1a, 12.3.16, 12.3.17 and 12.3.21. Often too narrow to be mapped at 1:100 000 scale. The regional ecosystems recognised by Bean et al. (1998) indicate that geographical patterns are evident within the RE. Occurs up to about 100 km inland. Extensively cleared for agriculture. Prone to invasion by weeds such as camphor laurel Cinnamomum camphora, broad leaved pepper tree Schinus terebinthifolius, cat's claw creeper Macfadyena unguis-cati on margins and when disturbed. 12.3.1a: Was previously mapped as 12.3.1. Found in wetter environments than 12.3.16 and 12.3.17. Restricted to the high rainfall catchments of the Gold and Sunshine Coast hinterlands and upper Albert and Mary Rivers. Extensively cleared for agriculture and urban development. Prone to invasion by weeds such as camphor laurel Cinnamomum camphora, broad leaved pepper tree Schinus terebinthifolius, cat's claw creeper Dolichandra unguis-cati on margins and when disturbed. |
