| Structure code | Closed Forest |
| Description | Semi-deciduous complex notophyll feather palm vine forest. Argyrodendron actinophyllum subsp. diversifolium may be prominent in the emergent layer or in the canopy. Other emergents may include Alstonia scholaris, Terminalia sericocarpa, Cryptocarya hypospodia and Trema orientalis. The canopy is typically dominated by species such as Myristica globosa subsp. muelleri, Archontophoenix alexandrae, Acmenosperma claviflorum, Cryptocarya hypospodia, Endiandra cowleyana, Argyrodendron actinophyllum subsp. diversifolium, Beilschmiedia obtusifolia, Alstonia scholaris, Planchonella myrsinodendron and Dysoxylum alliaceum. There is usually a sub-canopy of species such as Archontophoenix alexandrae, Myristica globosa subsp. muelleri, Acmenosperma claviflorum, Dysoxylum alliaceum, Endiandra cowleyana, Alstonia scholaris and Ptychosperma elegans. Lower tree and shrub may include Myristica globosa subsp. muelleri, Archontophoenix alexandrae, Polyscias australiana, Diospyros hebecarpa, Ixora timorensis, Wilkiea macrophylla, and Cleidion javanicum. The very sparse ground layer includes species such as Alpinia caerulea, Blechnum cartilagineum and Pollia macrophylla. Common vines are Melodinus australis, Rourea brachyandra and Cissus antarctica, and epiphytes include Asplenium australasicum and Platycerium bifurcatum. Occurs in gullies and slopes on rolling hills and mountains of foothills and uplands. Geologies mapped as Kp (Proserpine Volcanics) and Pll (Airlie Volcanics). Early Cretaceous - Early Permian acid to intermediate pyroclastics and flows. Includes rhyolite and andesite. Not a Wetland. (BVG1M: 5b). |

| Special values | 8.12.19: Habitat for the threatened plant species Trigonostemon inopinatus and Graptophyllum ilicifolium. Habitat for the near threatened plant Rhodamnia glabrescens, Sarcotoechia heterophylla. Also habitat for plant species at their southern range limit such as Dysoxylum papuanum, Gossia myrsinocarpa, Erycibe coccinea, Xylopia maccreae, Zanthoxylum nitidum, Tritaxis australiensis and Geophila repens, and species at their northern range limit such as Mezoneuron scortechinii and Bosistoa pentacocca, species poorly known in the Central Queensland Coast bioregion such as Marsdenia glandulifera, Corymborkis veratrifolia and Hedraianthera porphyropetala, and species with restricted range such as Gossia pubiflora. Habitat for fruit pigeons and endemic leaf-tail geckoes. |

| Comments | 8.12.19: Distinguished from most other land zone 12 regional ecosystems by occurrence on the mainland, and by the common presence of Myristica globosa subsp. muelleri and/or Archontophoenix alexandrae in the subcanopy or canopy, and the usual presence of Argyrodendron actinophyllum in the canopy or as emergents. The most similar RE however is 8.12.1b which has a very similar species composition and tends to occur with and grade into 8.12.19. The best way to distinguish these regional ecosystems is by landform, with moist gullies and sheltered aspects more likely to contain 8.2.19 whilst the ridges and spurs will contain 8.12.1b. May be similar to 8.12.1a, but in this vegetation community Myristica globosa is either not present or is rare. Also 8.12.19 lacks the prominent presence of higher altitude species such as Acmena resa and Syzygium wesa which occur frequently in 8.12.1a. Occurs on ranges in subregions 1 and 3. Mapped in Dryander and Conway National Parks, along the Clarke and Connors Ranges from west of Cathu to 15km south of Credition and in small patches south to Sarina. Some areas have been logged and some have been subject to clearing. Subject to pig damage. |
