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 43 Map Unit 2b Bruguiera parviflora mid closed-forest/mid open-forest (tidal creek forest) This forest occurs along tidal creeks and tributaries and is generally dominated by Bruguiera parviflora in all three strata, forming mono-specific stands in some areas. Rhizophora stylosa, Camptostemon schultzii and Avicennia marina are common components, particularly along the waters edge, while scattered Xylocarpus mekongensis and occasional Aegiceras corniculatum, Bruguiera exaristata, Ceriops decandra, Ceriops tagal, Excoecaria ovalis, Melaleuca cajuputi and Aegialitis annulata also occur. Regeneration of Bruguiera parviflora comprises a significant proportion of the lower cover. Geomorphic Unit: Tidal Creek, Tidal Creek Bank, Tidal Creek Shoal Tidal Level: Mean Sea Level to Mean High Water Neap Area: 20.2 ha (0.06%) Table 13.

It tends to replace the true tidal creek communities, particularly in the upper reaches of the tidal creeks in the upper reaches of the Harbour. Associated Vegetation Types: This community is similar to the tidal creek community (map unit 2a), although contains a much greater proportion of Bruguiera parviflora. It is not as common in Darwin Harbour, described as map unit 2 in the original survey.
