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 40 Map Unit 1d Rhizophora stylosa low open-forest This map unit is described as a low open-forest dominated by Rhizophora stylosa with scattered Avicennia marina, Ceriops tagal and Aegialitis annulata. It occurs on rocky substrates and is a depauperate form of the other Rhizophora stylosa communities. Geomorphic Unit: Rocky Shore/Cheniers Tidal Level: Mean Sea Level to Mean High Water Spring Area: 9 ha (0.03%) Species Richness: 4 Table 11.

No mid stratum was discernible with a dense tangle of roots, trunks and branches forming on lateritic rocky shores. Soils are muddy sands between rock, gravel sheets or boulder deposits (Brocklehurst & Edmeades 1995). Uncommon in Bynoe Harbour, this community is best developed around the Charles Point region. Associated Vegetation Types: This map unit is similar in habit to map unit 1c and tidal creek communities (map units 2a-2c). It is equivalent to map unit 9 in the original Darwin Harbour survey and 1e in the Bynoe Harbour survey.
