| Short description | Evergreen notophyll Ristantia waterhousei mossy forest of uplands on rhyolite |
| Structure code | Closed Forest |
| Description | Evergreen notophyll mossy forest. The canopy is dominated by Ristantia waterhousei. Other canopy species may include Pleioluma queenslandica, Cryptocarya macdonaldii, Cryptocarya murrayi, Archontophoenix alexandrae, Argyrodendron actinophyllum subsp. diversifolium, Cinnamomum laubatii, Cryptocarya grandis, Elaeocarpus eumundi, Cryptocarya vulgaris, Cryptocarya onoprienkoana and Sloanea langii. Hanging bryophytes on tree branches are abundant and conspicuous. sub-canopy and lower tree layers may include Archontophoenix alexandrae, Neisosperma poweri, Neolitsea dealbata, Diospyros pentamera and Guioa lasioneura. Occasional shrubs or low saplings are Wilkiea macrophylla, Tasmannia insipida, Medicosma obovata, Polyscias australiana, Psychotria loniceroides, Psydrax lamprophylla and Tapeinosperma pseudojambosa. Scattered ground stratum plants include Blechnum cartilagineum, Arachnoides aristata, Calanthe triplicata, Epiphytes include Asplenium australasicum, Arthropteris tenella and Dockrillia teretifolia. Common vines are Cissus antarctica, Embelia australiana, Smilax australis and Calamus australis. Confined to upper slopes and crests on rolling to steep mountains of uplands. Geology probably mainly rhyolite, but mapped as Kp (Kp = Proserpine Volcanics) and Kg. Early Cretaceous rhyolite, andesite, minor pyroclastics, leucocratic alkali granite, granophyre and quartz syenite. Not a Wetland. (BVG1M: 6b). |
| Protected areas | Dryander NP |
| Special values | 8.12.30: A rare regional ecosystem dominated by an endemic threatened plant species Ristantia waterhousei. Also habitat for vulnerable plant species Medicosma obovata. Also habitat for plant species at the southern limit of their range such as Cestichis nugentiae and species poorly known in the Central Queensland Coast bioregion such as Dockrillia teretifolia. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. ISSUES: Fire sensitive. |
| Comments | 8.12.30: Distinguished from all other closed forest ecosystems on land zone 12 by the dominance of Ristantia waterhousei in the canopy. Confined to Mt Dryander in subregion 1. Approximately 15km north of Proserpine and 15km west of Airlie Beach. Probably good given the remoteness, and is probably fairly resistant to weed invasion having a heavily closed canopy. |
