| Structure code | Low Closed Forest |
| Description | Mangrove and vine forest closed scrub and closed forest to open forest. Inland margins of mangroves and estuaries. Intertidal. (BVG1M: 35a). Vegetation communities in this regional ecosystem include: 7.1.4a: Mesophyll vine forest/mangrove complex. Canopy species include Heritiera littoralis, Bruguiera gymnorhiza, Sonneratia alba, Barringtonia racemosa, Archontophoenix alexandrae, Elaeocarpus grandis, Melicope elleryana, Acacia mangium and Syzygium tierneyanum. Inland margins of mangroves and estuaries. Intertidal. (BVG1M: 35a). 7.1.4b: Simple mesophyll vine forest with Barringtonia racemosa and/or Hibiscus tiliaceus, +/- Heritiera littoralis on mangrove fringes. Semi-permanently inundated brackish swamps. Intertidal. (BVG1M: 35a). 7.1.4c: Mangrove closed scrub and closed forest to open forest, with Livistona drudei emergents. Stream banks on upper limit of saline influence. Intertidal. (BVG1M: 35a). 7.1.4d: Riverine communities dominated by Nypa fruticans. Tidal stream banks at the upper limit of saline influence. Intertidal. (BVG1M: 35a). |

| Protected areas | Gulngay NP, Daintree NP (CYPAL), Girringun NP, Russell River NP, Hull River NP, Maria Creek NP, Hinchinbrook Island NP, Girramay NP, Ella Bay NP, Carello Palm Swamp CP |
| Special values | 7.1.4: Habitiat for threatened epiphyte species (e.g. tassel ferns and orchids). 7.1.4d: These Nypa fruticans communities are of special local significance. The very small population near Lucinda is the only known locality in the Wet Tropics. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately. ISSUES: Threatened epiphyte species (e.g., tassel ferns and orchids) require consideration. No fire management required. Non-flammable vegetation. |
| Comments | 7.1.4: Scattered along most of the coastal margin. 7.1.4a: Scattered along most of the northern coastal margin. 7.1.4b: Scattered along the coastal margin from Tully north. 7.1.4c: Rare, along the southern coastal margin. 7.1.4d: Rare, currently only known from near Lucinda. |
