| Short description | Mangrove closed scrub to open forest of areas subject to regular tidal inundation |
| Structure code | Low Closed Forest |
| Description | Mangrove closed scrub to open forest. Sheltered coastlines, estuaries, and deep swales between dunes, on fine anaerobic silts, inundated with saline water at high tide. Intertidal. (BVG1M: 35a). |
| Supplementary description | Stanton and Stanton (2005), E22a; Kemp and Morgan (1999), 1; Kemp et al. (1999), 1; Neldner and Clarkson (1995), 34, 132; Tracey and Webb (1975), 22a |

| Special values | 7.1.1: Important fish nursery areas. Threatened species include: Myrmecodia beccarii (ant plant) and Hypochrysops apollo apollo (apollo jewel butterfly). |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately. ISSUES: No fire management required. Non-flammable vegetation. The vulnerable ant plant (Myrmecodia beccarii) and the endangered Apollo jewel butterfly Hypochrysops apollo apollo) require consideration. |
| Comments | 7.1.1: Structure and composition varies greatly, depending upon distance from the sea and differential freshwater influence. The main river systems with extensive mangrove communities include the Annan, Bloomfield, Daintree, Barron, Mulgrave, Russell, Johnstone, Hull, Tully, Murray, Seymour and Herbert Rivers and Mourilyan Harbour and Trinity Inlet. |
