Description

This report describes the updated mangrove communities for the approximately 32,000 ha of mangroves and salt flats that line the foreshores of Darwin Harbour, Shoal Bay and areas south of Charles Point and Gunn Point. Results indicate that there has not been any significant, discernible or substantive changes in mangrove forest composition in Darwin Harbour between 1996 and 2016.

Mangrove Monitoring Project: Sub-project A 37 Distribution and Habitat Notes: Located at the seaward edge of the mangrove forest, this community forms a discontinuous band around the shoreline, usually being restricted to shores facing the main Harbour waters. Moving up the tidal creek systems, it gives way to the low Rhizophora stylosa tangle (map unit 1c) at creek mouths. Its near shore position upstream is replaced by varieties of tidal creek communities (map units 2a, 2b or 2c). Trees range from 8-18 m high, with the major proportion of crown cover being in the top stratum. Trees are straight, with branching occurring only in the upper reaches. The substrate is root structured. It is common to find open areas in this zone caused by lightning strikes. At the seaward margin, either an open forest of Sonneratia alba or bare mudflats are common. When present, the boundary between the two forests is distinct. Trunks, branches and roots suffer from invertebrate damage by the bivalve Teredo sp. These are the tallest of all the mangrove communities. Associated Vegetation Types: Equivalent to Darwin Harbour mangrove map unit 1.
