Land-based sources of toxic runoff are an important cause of habitat degradation in coastal watersheds and nearshore marine environments throughout the United States. The Ecotoxicology Program conducts research to identify key threats to NOAA trust species and habitats. In recent years this work has focused on coho salmon as a sentinel species for ecological resiliency in western watersheds impacted by urbanization and stormwater runoff from roads, parking lots, and other impervious surfaces. The research has focused on the health and survival of salmon embryos, juveniles, and returning adult spawners, using a combination of laboratory studies, field assessments, population modeling, food web modeling, and land-use based ecological forecasting.
