Mangrove Monitoring Project: Sub-project A 50 Map Unit 4c Ceriops tagal low closed-forest/low open-forest (hinterland) The upper stratum dominates this community. Ceriops tagal is the dominant species, and often forms nearly pure stands. Other species that may occur occasionally include Avicennia marina, Bruguiera exaristata, Excoecaria ovalis and Lumnitzera racemosa. This community is taller than the other Ceriops communities. Geomorphic Unit: High Tidal Flat Tidal Level: Mean High Water Neap to Mean High Water Springs Area: 271 ha (0.9%) Species Richness: 5 Table 19.

Associated Vegetation Types: This map unit is similar to map unit 4b but taller, and may also form patches within the low Ceriops tagal unit (map unit 4a). It is depicted as map unit 6 in the original Darwin Harbour survey.
