Threatened and Endangered Species Protection

An “endangered” species is one that is in danger of extinction throughout all or a significant portion of its range. A “threatened” species is one that is likely to become endangered in the foreseeable future.


  • Protecting threatened and endangered (T&E) wildlife and plants from the impacts of disease, invasive species, and predators is one focus of the APHIS Wildlife Services (WS) program. WS’ T&E species activities are conducted in collaboration with the U.S. Fish and Wildlife Service (FWS), State wildlife management agencies, conservation organizations, private landowners, and others.
  • During FY 2013, WS’ research and operational efforts contributed to the conservation of 165 threatened and endangered species: birds (50), mammals (28), reptiles (14), amphibians (4), fish (9), clams (3), snails (4), insects (1), and plants (52).
  • WS T&E activities were conducted in 34 States, as well as in Guam, the Virgin Islands, and Cuba.
  • Of the 165 listed species conserved by WS, 60 species are State listed only and 105 species are Federally listed (including some that are also State listed).
  • More than $6.6 million in funds were expended by WS on T&E conservation during FY 2013.
