An integrated environmental assessment of a coastal wetland will be presented using Awase wetland (N 26° 18.47, E 127° 58.12, Subtropics) as a case study site. Environmental indicators are selected, and the current environmental status for the indicator species (groups) are described by the Habitat Suitability Index (HSI) methodology. Based on the standing stock biomass and its fraction of each species (groups) are used as an indicator of the assessment. Subsequently the impact of a future large-scale landfill development on the wetland was evaluated. Large losses in optimal habitat (>20%) are recorded in large seagrass area, benthic zones IV (Gastropod dominant) and VI (Annelid dominant), and Kubiremidoro (green algae), with significant losses (>10%) in benthic zone V (Annelid and Arthropod dominant). The relative proportion of optimal area for the each species (groups) doesn't change except for a special type of benthic zone IV. This attempt of assessment gives a guideline for integrated coastal ecosystem management of the area.
