| Regional ecosystem | 3.12.2 |
|---|---|
| Vegetation Management Act class | Of concern |

| Biodiversity status | Of concern |
| Subregion | 1, 2, (6) |
| Estimated extent1 | Pre-clearing 8000 ha; Remnant 2021 8000 ha |
| Short description | Araucarian notophyll vine forest on granitic ridges and mountains |
| Structure code | Low Closed Forest |
| Description | The uneven canopy (8-15m tall) is dominated mainly by evergreen species. Buchanania arborescens (native mango), Dysoxylum oppositifolium (pink mahogany), Acacia midgleyi or A. disparrima subsp. calidestris (brown salwood), A. polystachya (a wattle) and Sterculia quadrifida (peanut tree) are frequent dominants. The very sparse emergent layer (17-30m tall) of Araucaria cunninghamii (hoop pine) is a conspicuous feature of this unit. Polyscias elegans (celery wood) and Polyalthia nitidissima (canary beech) are dominant species in the mid-dense sub-canopy (6-8m tall) layer. A sparse shrub layer (1-3m tall) is dominated by Acronychia laevis (hard aspen), Atractocarpus sessilis (false gardenia) and Myrsine porosa (northern muttonwood). Thin wiry vines are common and vascular epiphytes scarce. The ground layer is very sparse composed of isolated clumps of seedlings and ferns. Occurs on ridges and upper slopes of the predominantly granite. Not a Wetland. (BVG1M: 2b). |

| Protected areas | KULLA (McIlwraith Range) NP (CYPAL), Cape Melville NP (CYPAL), Oyala Thumotang NP (CYPAL) |
| Special values | 3.12.2: The vulnerable plant species Arenga australasica, Paramapania parvibractea, and Syzygium macilwraithianum, endangered species Phlegmariurus carinatus, and near threatened species Donella lanceolata, occur in this ecosystem. Important genetic populations of native plantation tree Araucaria cunninghamii. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: No deliberate fire management required within this unit. Undertake fuel reduction burns in surrounding vegetation utilising multiple small fires throughout the appropriate season to manage biodiversity values and to limit the extent and reduce risks of wildfire. ISSUES: Fire sensitive vegetation type. |
