| Biodiversity status | No concern at present |
| Subregion | 7, 4, 1, 2, 9, (6), (3), (5), (8), (2.1) |

| Short description | Ceriops tagal and/or C. australis +/- Avicennia marina low open forest |
| Structure code | Low Open Forest |
| Description | Low open forest to closed forest of Ceriops tagal (yellow mangrove) +/- Avicennia marina (grey mangrove) +/- Excoecaria agallocha (milky mangrove). A. marina can also occur as an emergent. A very sparse to dense mixed shrub layer can often include C. tagal, Bruguiera spp. and Xylocarpus spp. The very sparse ground layer can contain patches of Sporobolus virginicus (marine couch) and Acrostichum spp. (mangrove ferns) or small clumps of Batis argillicola. Occurs in downstream to intermediate estuarine areas in the high to mid intertidal zones throughout the bioregion. Intertidal. (BVG1M: 35a). |
