Mangrove Monitoring Project: Sub-project A 61 Table 26. Map unit 8 structural formation and stand information Strata Life Form Median Cover (%cc) Median PFC (%) Median Canopy Height (m) Upper tree 45 (25 - 70) 23 (15 - 49) 8 (6 - 11) Mid tree 3 (0 - 50) 2.5 (0 - 4) Lower tree 0 (0 - 20) 0 (0 - 0.8) Distribution and Habitat Notes: Restricted to the seaward side of the main tidal flats and the mouths of tidal creeks, and to a limited extent to regions upstream. It is generally found as a transition between the Rhizophora forests (1a,1b) and the seaward edge of the mudflats. The substrate of fine muds are waterlogged and root structured (pneumatophores). Slope is moderate with a median value of 4 where inundation occurs twice daily. Hollows are common in the larger Sonneratia alba trees. It is identified as map unit 8 in the original Darwin Harbour survey and 8a and 8b in the Bynoe Harbour survey.
