| Short description | Semi-evergreen to evergreen notophyll vine forest on gently to moderately sloping alluvial fans adjacent to ranges |
| Structure code | Closed Forest |
| Description | Semi-evergreen to evergreen notophyll vine forest. This ecosystem is primarily defined by its landform, occurring on fans at the base of ranges, and excluding riparian rainforest. Dominants are very variable. Emergents may include Eucalyptus tereticornis, Acacia fasciculifera and Cryptocarya hypospodia. The canopy may include species such as Dissiliaria indistincta, Terminalia melanocarpa, Argyrodendron polyandrum, Cleistanthus dallachyanus, Cryptocarya triplinervis, Cryptocarya vulgaris, Cryptocarya hypospodia and Miliusa brahei. The sub-canopy may include species such as Mallotus philippensis, Bosistoa pentacocca, Aidia racemosa, Chionanthus ramiflorus, Cleistanthus dallachyanus, Diospyros hebecarpa and Drypetes deplanchei. The lower tree and shrub layers may consist of Tabernaemontana orientalis, Alyxia ruscifolia, Acronychia laevis, Fitzalania heteropetala, Psydrax lamprophylla and Carallia brachiata. The ground layer is very sparse with typical species including Oplismenus aemulus, Aneilema acuminatum and Pseuderanthemum variabile. Common vines are Cissus oblonga, Trophis scandens and Tetrastigma nitens. Epiphytes include Platycerium bifurcatum and Dendrobium discolor. Fans, terrace flats and plains (at the bases of ranges) on level alluvial plains to undulating hills of lowlands and foothills. Geologies are mapped as Qr, Qa and Qf (Quaternary clay, silt, sand, gravel and soil; mainly alluvium, some colluvium, residual deposits, floodplain alluvium, flood-out sheets and small fans). Not a Wetland. (BVG1M: 4a). |

| Special values | 8.3.10: Habitat for threatened plant species Medicosma obovata, Neisosperma kilneri, Omphalea celata, Ristantia waterhousei and the near threatened plant species Brachychiton compactus and Rhodamnia glabrescens. Habitat in some areas for restricted plant species such as Argyrodendron sp. (Whitsundays W.J.McDonald+ 5831), Gossia pubiflora and Dissiliaria indistincta, and for species poorly known in the Central Queensland Coast bioregion such as Brachychiton acerifolius and Corymborkis veratrifolia. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. ISSUES: Fire management in adjacent areas may need to take into consideration the emergence of this ecosystem into adjacent sclerophyll communities. |
| Comments | 8.3.10: Floristically variable and best distinguished from other rainforest ecosystems on alluvium its occurrence on fans close to the bases of ranges, and excluding riparian situations. Occurs in the area of the Dryander Ranges and Conway National Park, with occasional areas to the west of Mackay. Also found to the west of Island Head Creek in the Shoalwater Bay Military Training Area. Ranges from good to poor. Is suffering weed invasion in some parts. Common weed species are *Lantana camara, *Passiflora suberosa, *P. pallida and *Rivina humilis. |
