Darwin Harbour; Shoal Bay
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 53 Map Unit 5c Mixed species low open-forest/low closed-forest For this community, Lumnitzera racemosa, Avicennia marina, Excoecaria ovalis and Ceriops tagal can be co-dominant or locally dominant with a median height of 3 m. Each species may also form mono-specific stands of low closed-forest and low open-forest. On landward edges, grasses and sedges such as Sporobolus virginicus and Fimbristylis spp. dominate the lower stratum. Samphire species are also characteristic in some instances. Geomorphic Unit: High Tidal Flat Tidal Level: Mean High Water Neap to Mean High Water Spring Area: 681 ha (2.2%) Species Richness: 6 Table 22.
