General Impacts by the Tsunami
§ Damage to structure and function of coastal ecosystems: coral reefs, mangroves, sea grasses, estuarine mudlfats
§ Physical damage – physical removal of flora, fauna, reefs, sea grasses and increased sedimentation
o Physical damage by wave energy – on “shallow near shore habitats (those of coral reefs, sea grasses and mangroves)
§ Chemical changes – saltwater intrusion, eutrophication, sewage
§ Change in ecosystems – different species from different trophic levels were taken away or disrupted
Specific References to Seagrass:
- Indonesia: 20% of seagrass beds, 30% of coral reefs, 25-35% of wetlands were damaged on west coast
- Thailand: 10% damage of seagrass beds
