The National Marine Fisheries Service, U.S. Fish and Wildlife Service, and Environmental Protection Agency have developed a framework for analyzing potential effects of national pesticide registrations on species listed under the U.S. Endangered Species Act (ESA).  Currently, the agencies are implementing the framework by developing biological evaluations and biological opinions. As risk is a function of exposure and response (effects), a key aspect of risk reduction is minimizing the amount of pesticides entering species habitats (i.e., reducing exposure levels).  Pesticide labels authorize legal use in the U.S. by generally dictating where, when, how, and how much of a pesticide product may be applied.  These parameters, along with conservation practices, will be discussed in the context of documenting reductions in pesticides entering aquatic habitats, thereby reducing a species’ exposure.  The gold standard for best practices includes those that are simple, efficacious, validated, and cost-effective.
