| Description | Gleichenia dicarpa (coral fern), Gahnia sieberiana (red fruit saw sedge), Palhinhaea cernua (coral fern), and Pseudolycopodium densum (bushy clubmoss) closed fernland. Granite highlands, on Thornton Peak and Mt Bartle Frere. Palustrine. (BVG1M: 34f). |
| Supplementary description | Stanton and Stanton (2005), G158; Tracey and Webb (1975), 10 |
| Protected areas | Wooroonooran NP, Daintree NP (CYPAL) |
| Special values | 7.12.67: Potential habitat for NCA listed species: Drosera prolifera, Parsonsia bartlensis. |
| Fire management guidelines | SEASON: Oct-Dec (occasionally Sep). INTENSITY: Variable, depending on fuel. INTERVAL: 10-20 years. There will be practical difficulties in attempting to burn grassland and sedgeland at different intervals. INTERVAL_MIN: 10. INTERVAL_MAX: 20. STRATEGY: 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: 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 | 7.12.67: This is a wetland. The persistence of this regional ecosystem may be related to fire or shallow soils. Limited to Bartle Frere South Peak and Thornton Peak. |
