| Short description | Semi-deciduous complex notophyll vine forest on perched alluvials in valleys of undulating mountain ranges |
| Structure code | Closed Forest |
| Description | Semi-deciduous complex notophyll vine forest. Frequent emergents are Argyrodendron actinophyllum subsp. diversifolium, Falcataria toona and Trema orientalis. The canopy is often dominated by species such as Argyrodendron actinophyllum subsp. diversifolium, Archontophoenix alexandrae, Acmenosperma claviflorum, Myristica globosa subsp. muelleri, Beilschmiedia obtusifolia, Cryptocarya hypospodia and Planchonella myrsinodendron. Common vines in the canopy include Austrosteenisia blackii and Cissus hastata. Lower tree layers frequently consist of similar species to the canopy, but also particularly Archontophoenix alexandrae, Macropteranthes fitzalanii, Baloghia inophylla, Bosistoa pentacocca subsp. connaricarpa and Backhousia citriodora. There are often one or more sparse shrub layers consisting of saplings from the upper layers as well as Acronychia laevis, Atractocarpus fitzalanii, Cupaniopsis wadsworthii, Ficus fraseri, Gossia pubiflora, Dendrocnide spp., Ixora spp., Psychotria spp. and many vines. The ground stratum is sparse, with typical species being Oplismenus aemulus, Pseuderanthemum variabile, Aneilema acuminatum and Geophila repens. Occurs on perched alluvials in valley flats of rolling mountains. Not a Wetland. (BVG1M: 4a). |
| Protected areas | Conway NP |
| Special values | 8.3.9: Habitat for Lepiderema sp. (Impulse Creek A.B.Pollock 73) which is currently known from only a very limited area. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. ISSUES: Generally this ecosystem is self protecting from fire due to high moisture gradients and surrounding vine forest. |
| Comments | 8.3.9: Distinguished from all other rainforest regional ecosystems by its occurrence on Quaternary alluvium in perched valleys of undulating mountain ranges. Most closely related to 8.3.10 which occurs on colluvium, and 8.3.1a which occurs on Quaternary alluvium of the lowlands. Occurs to the west of the Conway Range around Repulse Creek and The Inlet, subregion 1. Possibly previous logging disturbance. |
