The Endangered Species Act of 1973

Robin Spratling APES

What is the ESA?

This act is a National law that was created by the Convention on International Trade in Endangered Species of Wild Fauna and Flora. It was adopted in the United States on March 3, 1973.



  • Created and maintains a list of endangered and threatened species
  • Makes illegal trading, selling, possessing, or taking any endangered species
  • Allows for the creation of lands for the protection of these species
  • Grants aid to States to protect these species
  • Creates legal punishment: civil and criminal punishments for any violations of the act.
The ESA is led by the U.S. Fish and Wildlife Service and the U.S. National Oceanic and Atmospheric Administration.


There are currently around 2100 species on the list of protected species (EPA 2012).



Successes

The Black Footed Ferret


In the 1900s, there were over 5 million ferrets across the US, however the population of the ferrets was quickly diminishing. In 1967, the last black footed ferret in captivity died and the species was thought to be extinct. However, in 1981, a small population was discovered in Wyoming. Due to the help of the ESA, there are now over 1400 black footed ferrets living in the US.

Gray Wolf of the Northern Rocky Mountains

The Gray Wolf was endangered from the 19th century to the mid 1900s. Then was moved to the threatened species list. After the creation of the ESA, the Gray Wolf was protected and reintroduced into Yellowstone National Park. The population is now in the 1700s. And in 2011, the Gray Wolf was officially moved off the endangered species list. However, the Gray Wolf still needs protection because it is being hunted extensively in the Rocky Mountain region.

Weaknesses/Improvements

  • The ESA does not include any portion that keeps species from becoming at-risk
  • Unclear whether recovery methods are science based
  • There are no requirements about the types of recovery methods

The ESA could be improved by including more direction and rules about methods of recovery for endangered species. The methods in which recovery should happen are not laid out in the act, so recovery methods vary greatly and can be inconsistent or not based completely in science. Also, animals should continue to be monitored even after they are removed from the endangered species list. Because in the case of the Gray Wolf, when it was removed from the list, people began hunting and trapping them. This could cause the Gray Wolf to become endangered again.


Amendements

There was an amendment created in 1978 asserting that the Secretary of Defense must determine the critical nature of environments across the nation and designate which lands should be protected as a critical habitat.
