Behavioral observations - Evaluating the impacts of pesticides on ESA-listed salmon and their habitats

Long-running science support for the agency (Office of Protected Resources, others) related to the use of modern pesticides throughout the United States as a limiting factor for endangered species conservation and recovery. This work is currently supporting several national ESA Biological Opinions, and is under review by the National Academy of Sciences. The NAS panel recommendations are expected in the summer of 2013, and these will guide additional research in FY14 and beyond.
