Which federal agency determines what species are endangered?

The Fish and Wildlife Service (FWS) is the federal agency responsible for determining which species are classified as endangered under the Endangered Species Act (ESA). This agency conducts scientific assessments and studies to evaluate the population status and risks facing species, allowing them to make informed decisions about listing species as endangered or threatened. The FWS works to protect these species and their habitats, engaging in conservation efforts and recovery plans to prevent extinction.

In contrast, other agencies like the U.S. Department of Agriculture primarily focus on agricultural practices and resources, while the Office of Pesticide Programs (OPP) of the EPA is more concentrated on regulating pesticides and their effects on the environment rather than directly determining species status. The National Oceanic and Atmospheric Administration (NOAA) often works closely with the FWS on marine species and habitats but does not hold the primary responsibility for making endangered species determinations. These roles clarify why the FWS is the correct choice for determining endangered species.
