| Short description | Mangrove shrubland to low closed forest on marine clay plains and estuaries |
| Structure code | Low Closed Forest |
| Description | Mangrove shrubland to low closed forest. Occurs on Quaternary estuarine deposits. Intertidal. (BVG1M: 35a). Vegetation communities in this regional ecosystem include: 12.1.3a: Aegiceras corniculatum dominated low closed forest. Occurs on Quaternary estuarine deposits in the middle to upper tidal plane, in areas occasionally subject to freshwater influence. Intertidal. (BVG1M: 35a). 12.1.3b: Avicennia marina subsp. australasica dominated shrubland to low closed forest. Occurs on Quaternary estuarine deposits. Intertidal. (BVG1M: 35a). 12.1.3c: Bruguiera gymnorhiza dominated shrubland to low closed forest. Occurs on Quaternary estuarine deposits usually at the upper tidal limit of rivers and subject to freshwater influence. Intertidal. (BVG1M: 35a). 12.1.3d: Ceriops australis dominated shrubland to low closed forest. Occurs on Quaternary estuarine deposits. Intertidal. (BVG1M: 35a). 12.1.3e: Rhizophora stylosa dominated shrubland to low closed forest. Occurs on Quaternary estuarine deposits. Intertidal. (BVG1M: 35a). 12.1.3f: Intertidal water bodies. Occurs on Quaternary estuarine deposits where organic material (roots and detritus) prevent draining of tidal waters. Intertidal. (BVG1M: 34a). 12.1.3g: Mangrove dieback area leaving bare soil or ponding. Occurs on Quaternary estuarine deposits. Intertidal. (BVG1M: 35a). |

| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn. ISSUES: Scorching within the supra-littoral margin, particularly when this ecotone merges into flammable vegetation such as woodlands and forests of melaleuca may be a problem. |
| Comments | 12.1.3g: Mangrove communities are experiencing dieback from natural and human-related causes throughout Queensland. Mangrove dieback can have many causes such as weather, insects and disease, nutrients, climate change and pollution. http://tinyurl.com/mangrove-dieback. |
