that 70 percent have been lost to development, rising seas, and other threats. One factor scientists always thought marshes could withstand was nutrient enrichment — such as the flow of nitrogen and phosphorus from fertilizers and septic systems. But a nine-year study led by Marine Biological Laboratory scientist Linda Deegan showed that an over abundance of nutrients may be contributing to the demise of these salt marshes. In a Yale Environment 360 interview, Deegan describes the implications of this study and the vital services that would be lost if marshes disappear — from nourishing marine species to providing a physical barrier for coastal communities during storms such as Hurricane Sandy.
