If you take a quick glance at the marsh next to Saquatucket Harbor in Harwich Port, Massachusetts, you will notice right away that some of the grass is missing. The cordgrass there, and all around Cape Cod, has been slowly disappearing for decades. "The cordgrass that's being destroyed here is the foundation species that builds salt marshes," explains marine ecologist Mark Bertness of Brown University. With support from the National Science Foundation, Bertness studies this critical...
