Mangrove forest dominated by Avicennia marina subsp. australasica, typically along the seaward margin of mangrove forests. Occurs on Quaternary estuarine deposits, on intertidal flats which are often dissected by tidal streams. Soils are often deep saline clays. Avicennia marina typically dominates pioneering mangrove communities with more unstable sediments, whereas Rhizophora spp. typically dominate areas with more stable sediments.
Mangroves are not a taxonomically unified group, but rather an ecological group that arose through convergent evolution and includes several different families. They are characterised by trees that are adapted to tolerate tidal inundation.
Mangrove communities provide a wide variety of services, including:
- physical coastal protection from erosion and flooding
- sediment trapping
- primary production
- nutrient uptake
- food source (Avicennia seeds) for Green sea turtles (Chelonia mydas)
- food, shelter and breeding areas for a wide range of fauna including birds, water mouse (Xeromys myoides) (landward margin), fish, crustaceans and other invertebrates
- prey for fish, which tend to use the edge of the mangroves when foraging.
Avicennia pneumatophores provide structural habitat for a range of fish, crustaceans and molluscs (including oysters and barnacles). The water mouse has also been observed hunting in pneumatophores, and nesting in the landward margin of mangrove forests. Dense growth of the red algae Catenella nipae on mangrove pneumatophores provides food for recreationally important herbivorous fishes.
Inundation 'Intertidal – Lower low', 'Intertidal – Mid low', 'Intertidal – Upper low', 'Intertidal – Low undifferentiated', 'Intertidal – Lower medium', 'Intertidal – Upper-medium', 'Intertidal – Medium undifferentiated', 'Intertidal – High', 'Intertidal – Undifferentiated', 'Intertidal – High undifferentiated', although mangroves usually occur at mean sea level and above.
Structural macrobiota 'Mangroves – Avicennia'
No qualifiers mapped, however Period and Trend are relevant as Rhizophora forests typically extend from the seaward boundary and can be influenced by sea level rise.
Relevant attributes associated with change (e.g. mangrove dieback) in Moreton Bay include Freshwater source, Freshwater volume and Trace elements/nutrients.
Relevant attributes associated with change for Gulf of Carpentaria include Inundation (sea level changes associated with extreme weather events).
The north-east coast of Australia was close to the centre of mangrove origin and dispersal. The climate is similar to that under which they first evolved, and the sheltered shallow waters of numerous estuaries are ideal for growth. Avicennia marina is the most common and widespread mangrove along the mainland coast of Australia, extending from Corner Inlet in Victoria to Bunbury in Western Australia.
The following relates to distribution of this ecosystem type within the Central Queensland mapping area:
- Avicennia marina or Ceriops spp. typically dominate higher energy areas from Tin Can Inlet to Round Hill Head, with mixed communities landward. In low energy waters from Tin Can Inlet to Round Hill Head, there are typically closed Avicennia/Ceriops forests landward of closed Rhizophora forests. Avicennia marina tends to dominate mangrove forests south of Fraser Island.
- Particularly important fisheries habitat from Round Hill Head to Tin Can Inlet, in terms of productivity, includes the Kolan, Elliott, Burrum, Mary and Susan rivers, Baffle and Kauri creeks, Great Sandy Strait and Tin Can Inlet. The smaller Broadwater, Littabella and Beelbi creeks are also important in terms of habitat diversity and connectivity with the larger nearby systems (Baffle Creek, and the Kolan and Burrum rivers).
Other relevant attributes include Consolidation, Energy and Sediment texture as mangrove communities typically occur on unconsolidated muds and fine sediments in low energy environments.
