Description Mangrove shrubland to low closed forest. Occurs on Quaternary estuarine deposits. (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. Estuarine wetlands (e.g. mangroves). (BVG1M: 35a)
12.1.3b: Avicennia marina subsp. australasica dominated shrubland to low closed forest. Occurs on Quaternary estuarine deposits. Estuarine wetlands (e.g. mangroves). (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. Estuarine wetlands (e.g. mangroves). (BVG1M: 35a)
12.1.3d: Ceriops australis dominated shrubland to low closed forest. Occurs on Quaternary estuarine deposits. Estuarine wetlands (e.g. mangroves). (BVG1M: 35a)
12.1.3e: Rhizophora stylosa dominated shrubland to low closed forest. Occurs on Quaternary estuarine deposits. Estuarine wetlands (e.g. mangroves). (BVG1M: 35a)
12.1.3f: Estuarine water bodies often with groundwater connectivity. Occurs on Quaternary estuarine deposits with groundwater connectivity. Estuarine wetlands (e.g. mangroves). (BVG1M: 34a)
12.1.3g: Mangrove dieback area leaving bare soil or ponding. Occurs on Quaternary estuarine deposits. Estuarine wetlands (e.g. mangroves). (BVG1M: 35a)

Fire management guidelines 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
