| Regional ecosystem | 7.8.12 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Not a Wetland |

| Supplementary description | Stanton and Stanton (2005), B283; Tracey and Webb (1975), 2a |
| Protected areas | Wooroonooran NP |
| Special values | 7.8.12: Threatened species include: Barongia lophandra, Carronia pedicellata, Diploglottis pedleyi, Endiandra globosa, Lepiderema largiflorens and Didymoglossum mindorense. Sersalisia sessiliflora and Samadera sp. (Barong B.Gray 742) are local endemics which are largely confined to this ecosystemt. Habitat for Syzygium erythrocalyx that also occurs in RE 7.8.2. |
| 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 | 7.8.12: North Johnstone River. Was logged to varying degrees, but is now mostly in National Park. Cyclone Winifred (1986) damaged much of this ecosystem and it is recovering well. |
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.
