- The Endangered Species Act of 1973 and its predecessors aim to protect species threatened with extinction. The Fish and Wildlife Service and National Marine Fisheries Service manage terrestrial/freshwater and marine species, respectively.
- Endangered species are in danger of extinction across all/most of their range, while threatened species are likely to become endangered in the foreseeable future. In 1995, the federal list contained over 1500 forms representing nearly 1000 biological species.
- A minimum viable population is the smallest population size needed for a species to survive and retain its evolutionary potential. The document concludes by listing the top 10 most endangered species globally according
