| Short description | Themeda triandra, or Imperata cylindrica, Sorghum nitidum and Mnesithea rottboellioides closed tussock grassland of metamorphic headlands and near-coastal hills |
| Structure code | Closed Tussock Grassland |
| Description | Themeda triandra (kangaroo grass), or Imperata cylindrica (blady grass), Sorghum nitidum (sorghum) and Mnesithea rottboellioides (northern canegrass) closed tussock grassland. Metamorphic headlands and near-coastal hills. Not a Wetland. (BVG1M: 32b). Vegetation communities in this regional ecosystem include: 7.11.39a: Grassland dominated by Themeda triandra in the Black Mountain area. Metamorphics. Not a Wetland. (BVG1M: 32b). 7.11.39b: Grassland dominated by Themeda triandra in areas other than Black Mountain. Metamorphics. Not a Wetland. (BVG1M: 32b). 7.11.39c: Imperata cylindrica, Sorghum nitidum and Mnesithea rottboellioides grassland. Metamorphic hillslopes. Not a Wetland. (BVG1M: 32b). |
| Supplementary description | Stanton and Stanton (2005), M59 in part (Qld Herbarium and WTMA (2005) M267a), Q59, M86 |
| Protected areas | Daintree NP (CYPAL), Ngalba-bulal NP (CYPAL), Hope Islands NP (CYPAL), Eubenangee Swamp NP, Russell River NP, Moresby Range NP, Mowbray NP |
| Special values | 7.11.39: A very rare ecosystem. A remnant in Eubenangee Swamp National Park (hill with walking track and look-out) remains in excellent condition but requires constant vigilant weed management. |
| Fire management guidelines | SEASON: Early season burns (April-June). Later burns during storm season will reduce shrub invasion. INTENSITY: Low, with occasional moderate. INTERVAL: 2-3 years. INTERVAL_MIN: 2. INTERVAL_MAX: 3. STRATEGY: Mosaic burn at a range of frequencies to create mosaic of post-fire responses. ISSUES: Absence of fire can lead to a transition to shrubland. Moderate intensity fire will reduce this change and assist with weeds. |
