Uplands, on sharply undulating metamorphics, of the moist rainfall zone. Contains Palustrine. (BVG1M: 7a). Vegetation communities in this regional ecosystem include: 7.11.29a: Evergreen microphyll vine thicket and low to medium simple microphyll vine forest with Uromyrtus tenella, Flindersia bourjotiana, Flindersia pimenteliana, Beilschmiedia oligandra, Ceratopetalum virchowii, Eidothea zoexylocarya, Steganthera macooraia, Alloxylon wickhamii, Cardwellia sublimis, Lomatia milnerae, Elaeocarpus johnsonii, Baloghia parviflora and Callitris macleayana. Uplands, on sharply undulating metamorphics. Not a Wetland. (BVG1M: 7a). 7.11.29b: Simple Notophyll Vine Forest with Ceratopetalum virchowii. Uplands, on sharply undulating metamorphics. A soil surface layer of fibric peat is common. Not a Wetland. (BVG1M: 7a). 7.11.29c: Sedgeland-shrubland complexes with emergent shrubs, fernland, with emergent shrubs, shrublands and low woodlands with Allocasuarina littoralis, Melaleuca quinquenervia, Rhodomyrtus sericea, Melastoma malabathricum subsp. malabathricum, Gahnia sieberiana, Schoenus sparteus, Ischaemum australe, Dianella sp. and Drosera spp. Uplands, on sharply undulating metamorphics. Palustrine. (BVG1M: 34f). 7.11.29d: Evergreen microphyll vine thicket and low microphyll vine forest with emergent Licuala ramsayi (fan palm) and Oraniopsis appendiculata. Uplands, on sharply undulating metamorphics. Not a Wetland. (BVG1M: 7a). |

| Protected areas | Wooroonooran NP, Daintree NP (CYPAL) |
| Special values | 7.11.29: Moderate floristic diversity. 7.11.29a and 7.11.29b have high regional and local endemism (e.g. Bubbia queenslandiana subsp. australis, Hexaspora pubescens and Symplocos boonjee. Threatened plant species include: Bubbia queenslandiana subsp. australis, Eidothea zoexylocarya, Hexaspora pubescens, Lepiderema largiflorens, Mammea touriga, Samadera baileyana. Other species of local significance are Symplocos hylandii and Elaeocarpus johnsonii. |
| Fire management guidelines | SEASON: Do not burn deliberately. c: Oct-Dec (occasionally Sep). INTENSITY: Do not burn deliberately. c: Variable, depending on fuel. INTERVAL: Do not burn deliberately. c: 10-20 years. There will be practical difficulties in attempting to burn grassland and sedgeland at different intervals. INTERVAL_MIN: 10. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately. c: Entire continuous areas are likely to burn at any one time. Burn 25-30% of these communities in WET in any one year. Attempt to time burning when water level is high enough to cover both peat and sedge bases. Protect from wildfire or manage surrounding country to reduce the potential of fire incursion. ISSUES: Typically unlikely to burn owing to lack of flammable grasses. Occasional high intensity fires along fringes, particularly on hillslopes, may lead to loss of rainforest at edges. Low intensity burns away from rainforest edge can be used to protect margins, when humidity and soil moisture are high. Where appropriate, use revegetation of rainforest species to provide buffer to cleared areas. Occasional high intensity fires in adjoining communities may be required to prevent expansion of rainforest elements. Vine thickets on slopes and peat soils may be particularly vulnerable ecosystems. c: A planned burn is likely to be over 100% of the planned burn area; so while mosaic burning is desirable to maintain structure and protect animal habitat and food, it will rarely be achievable. Under dry conditions, with little soil moisture, peat may burn as it is highly flammable in such circumstances. Sedges are disadvantaged by repeated high intensity fires. |
| Comments | 7.11.29: Occurs on a distinct, sharply undulating landscape. On shallower soils includes sclerophyll sedge and shrubland and fernland communities. Includes perched wetlands. Mainly the Francis Range (Toowalla area south of Mt Bartle Frere). |
