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).

Special values 12.1.3: Habitat for threatened fauna species including the false water-rat Xeromys myoides in the southern part of the bioregion particularly in areas immediately adjacent to saltpans, 12.1.2. ( Van Dyck and Gynther, 1996, 2003). 12.1.3a: Habitat for threatened fauna species including the false water-rat Xeromys myoides in the southern part of the bioregion particularly in areas immediately adjacent to saltpans, 12.1.2. ( Van Dyck and Gynther, 1996, 2003). 12.1.3b: Habitat for threatened fauna species including the false water-rat Xeromys myoides in the southern part of the bioregion particularly in areas immediately adjacent to saltpans, 12.1.2. ( Van Dyck and Gynther, 1996, 2003). 12.1.3c: Habitat for threatened fauna species including the false water-rat Xeromys myoides in the southern part of the bioregion particularly in areas immediately adjacent to saltpans, 12.1.2. ( Van Dyck and Gynther, 1996, 2003). 12.1.3d: Habitat for threatened fauna species including the false water-rat Xeromys myoides in the southern part of the bioregion particularly in areas immediately adjacent to saltpans, 12.1.2. ( Van Dyck and Gynther, 1996, 2003). 12.1.3e: Habitat for threatened fauna species including the false water-rat Xeromys myoides in the southern part of the bioregion particularly in areas immediately adjacent to saltpans, 12.1.2. ( Van Dyck and Gynther, 1996, 2003).
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.
