The Endangered Species Act (ESA) of 1973 is a U.S. federal law that mandates the protection of species threatened with extinction. The U.S. Fish and Wildlife Service and the National Oceanic and Atmospheric Administration oversee the management of these species and their habitats.12

The ESA protects threatened species through several key mechanisms:

  • Listing and Classification: Authorities maintain an endangered species list to identify organisms requiring protection, including subspecies and distinct population segments.12
  • Habitat Preservation: The law promotes the protection of critical habitats, which are areas designated as essential for a species' survival.12
  • Legal Prohibitions: It prohibits the unauthorized harvest, custody, trade, and transport of protected organisms, with violations subject to civil and criminal penalties.2
  • Cooperative Agreements: The federal government may establish agreements with and provide grants to states to support local conservation efforts.2

Species are monitored even after recovery to ensure population stability, and the law remains a vital tool for preventing the loss of biodiversity.1
