Tern Nesting Rafts

Floating nesting platforms give common terns safe ground as bay islands erode away beneath them.

About the program

How it works

Colonial waterbirds such as common terns and black skimmers nest on low bay islands — exactly the habitat being lost fastest to erosion and sea level rise. When an island washes out, a colony can lose an entire breeding season.

Floating nesting rafts, anchored in sheltered water and surfaced with shell and sand, give terns a predator-free place to nest that rises and falls with the tide. Nests are monitored through the season to track use and productivity.
