A project to restore eight beaches is helping bring back horseshoe crabs, birds and people’s hope for the future. This is how you build a #StrongerCoast.

Salt marshes provide habitat for fish, birds, and invertebrates and purify water by taking up nutrients that can be harmful in excess. They help protect neighboring coastal communities by buffering against wind and waves and absorbing, then slowly releasing, floodwaters. Salt marshes are threatened by sea-level rise and their tendency to gradually sink. The Fish and Wildlife Service is using a process called thin-layer deposition to restore these valuable habitats.
