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 59 Map Unit 7b Mixed species low woodland For this community, Avicennia marina, Bruguiera gymnorhiza and Ceriops tagal share dominance in the upper stratum. Bruguiera exaristata and Camptostemon schultzii are also present in the upper stratum in some instances. The mid stratum is mainly composed of Ceriops tagal, while the mangrove fern Acrostichum speciosum is abundant in the lower stratum in some regions. These communities generally abut freshwater swamps or drainage areas. Melaleuca cajuputi and Xylocarpus mekongensis may also be present. Geomorphic Unit: Hinterland/Tidal Flat Margin Tidal Level: Supra-tidal to Mean High Water Spring Area: 410 ha (1.3%) Table 25.

Tidal inundation is infrequent and the influence of fresh water is strong. Slopes are very gentle in this zone with a gradient of approximately 2. Small un-mappable areas of this unit are likely to occur throughout the harbour. Associated Vegetation Types: This community is somewhat similar floristically to the other hinterland communities .
