Endangered Species at 40-ES CoalitionPresident Richard Nixon signed into law, 40 years ago on December 28, the strengthened Endangered Species Act after Congress realized that without further protection from human actions, many of our nation’s plants and animals would become extinct.

The bipartisan 1973 legislation is credited with saving hundreds of species from extinction, including the bald eagle, America’s national bird, which increased from 416 pairs in 1963 to 9,789 pairs. 30 additional species have fully recovered thanks to the landmark law, including the Steller sea lion, the American alligator, brown pelican, and Virginia northern flying squirrel.

Politicians believed that America’s rich natural heritage is of “esthetic, ecological, educational, recreational, and scientific value to the Nation and its people.” Today, the ESA protects over 1,400 U.S. species and 600 foreign species, with hundreds of animal populations having soared since the conservation measures were first instituted.

Among the species to benefit are the whooping crane (which increased from 54 to 513 birds between 1967 and 2006); the Kirtland’s warbler (which increased from 210 to 1,415 pairs between 1971 and 2005); the peregrine falcon (which increased from 324 to 1,700 pairs between 1975 and 2000); the gray wolf (whose populations increased dramatically in the Northern Rockies, Southwest, and Great Lakes); the gray whale (which increased from 13,095 to 26,635 whales); and the grizzly bear (which increased from about 224 to over 500 bears in the Yellowstone area between 1975 and 2005).
