How Oysters Can Stop a Flood

Ask a Question

  • This video describes the benefits of oyster reefs for erosion control and preventing damage from strong storms and floods. 
  • The ecological benefits of oyster reefs are well-described in this video including flood control, erosion control, habitat engineering, and water filtration.
Teaching Tips


  • The video is short and provides nice animations to illustrate ecological concepts and demonstrate the historical ecosystems in the New York area.

Additional Prerequisites

  • Students should be familiar with the concept of sea level rise as a consequence of climate change.
  • There may be a commercial before the video.


  • Consider having students draw pictures to demonstrate the positive effects of oyster reefs to coastal ecosystems.
  • If students have never seen the ocean or coast, use Google Maps or another resource to help them visualize how intertidal habitats have a relationship with the nearby land.
  • Other resources related to this topic include this video about mussels and this video about coastal habitat.
Scientist Notes
This resource is a 6-minute video that discusses the roles that oysters and oyster reefs perform in protecting coastlines from erosion, filtering water, and generally promoting ecosystem health. However, over the past few decades, oyster populations have been in decline. This resource presents strategies for protecting and reintroduction oysters, and is recommended for teaching.
