Today on Marine Science Minute with Florida Sea Grant: Living Shorelines 

A close-up, low-angle view of sparse beach grass shoots growing in white sand, with a wide body of water and a cloudy blue sky blurred in the background.

Seawalls and bulkheads, or gray infrastructure, are traditionally used to stabilize shorelines.  

Large bundles of rough, grey oyster shells packed tightly into black mesh netting bags for reef restoration.

While gray infrastructure can protect shorelines, they can enhance erosion, are vulnerable to sea level rise, and displace valuable intertidal habitats.  

Living Shorelines uses nature, or green infrastructure to stabilize shorelines while restoring habitat, biodiversity, and ecological function to our estuaries.

Installing marsh grasses, mangroves, and oyster reefs make shorelines more resilient.  

Florida Sea Grant is training the next generation of professionals on living shoreline practice, fostering a growing green industry.
