| Structure code | Closed Forest |
| Description | Simple-complex mesophyll to notophyll vine forest. Lowlands and foothills on amphibolite, of the very wet and wet rainfall zones. Not a Wetland. (BVG1M: 1a). Vegetation communities in this regional ecosystem include: 7.11.25a: Mesophyll to notophyll vine forest. Lowlands and foothills on amphibolite of the very wet and wet rainfall zones. Not a Wetland. (BVG1M: 2a). 7.11.25b: Mesophyll vine forest recovering from disturbance, with Acacia celsa canopy or emergents. Lowlands and foothills, on amphibolite, of the very wet and wet rainfall zones. Not a Wetland. (BVG1M: 5d). |
| Supplementary description | Stanton and Stanton (2005), MA2a, MA2a(a); Tracey and Webb (1975), 2a |
| Protected areas | Russell River NP, Ella Bay NP |
| Special values | 7.11.25: Habitat for threatened plant species including Paramapania parvibractea. Most notable for the unusual and diverse floristic composition at low altitudes with Balanops australiana, Alloxylon wickhamii, Licuala ramsayi and Hydriastele wendlandiana. Other species of local significance include Nepenthes mirabilis (pitcher plant). |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately. Mosaic burning in surrounding fire-adapted ecosystems will minimise spread and severity of wildfire during severe weather events. ISSUES: Occasional hot fires in adjoining communities may be required to prevent expansion of rainforest elements. Edges are generally self-protecting but back burning from rainforest edges may be desirable. The occurrence of high biomass grasses in or adjacent to rainforest may detrimentally affect rainforest during fire events associated with dry weather. |
| Comments | 7.11.25: This regional ecosystem has an abundance of members of the Proteaceae family. Occurs on poorly-drained, iron-rich soils. Very poorly surveyed for flora or fauna. The Graham Range north of Innisfail. Selectively logged in the past where adequate access was available. Much of the extent is in good condition, albeit cyclone affected. |
1 Estimated extent is from version 13.1 pre-clearing and 2021 remnant regional ecosystem mapping. Figures are rounded for simplicity. For more precise estimates, including breakdowns by tenure and other themes see remnant vegetation in Queensland.
