| Short description | Evergreen notophyll vine forest with Melaleuca leucadendra on swamps |
| Structure code | Closed Forest |
| Description | Evergreen notophyll vine forest. A mid-dense to dense, even canopy (12-30m tall) is dominated by a variety of species including Buchanania arborescens (native mango), Syzygium forte subsp. potamophilum, Deplanchea tetraphylla, Lophostemon suaveolens (swamp mahogany) and Dillenia alata (red beech). Scattered emergent trees of Melaleuca spp. up to 33m in height are common, and in places form a sparse canopy. A sparse to mid-dense, sub-canopy tree layer (4-25m tall) is usually present. Dillenia alata is the most frequent species in this layer. The palms, Ptychosperma elegans, P. macarthurii, Licuala ramsayi (fan palm) and Archontophoenix alexandrae are conspicuous at some sites. Deciduous trees are generally infrequent. A variable shrub/low tree layer is present with Atractocarpus sessilis, Licuala ramsayi, Alyxia spicata (chain fruit), Calophyllum sil, Dillenia alata, Hydriastele wendlandiana and Tabernaemontana orientalis (banana bush) the most commonly encountered species. The ground layer is usually very sparse. Scattered ferns, Lindsaea spp., Lygodium flexuosum and Nephrolepis hirsutula may be locally abundant. Vines such as Flagellaria indica, Opilia amentacea and Smilax australis are occasionally present. Associated with swamps on alluvial plains. It also occurs on swamps in dune systems. Palustrine. (BVG1M: 4b). |

| Protected areas | Cape Melville NP (CYPAL), KULLA (McIlwraith Range) NP (CYPAL), Apudthama NP (CYPAL) |
| Special values | 3.3.6: The near threatened species Croton brachypus occurs in this ecosystem. |
| 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. |
