How effective is the Endangered Species Act?
Ninety-nine percent of species protected by the list have avoided extinction. Passed with bipartisan support in 1973, the Endangered Species Act (ESA) is our nation’s most effective law to protect species from extinction.
Grizzly bears, humpback whales, and bald eagles are just some of the 46 species now listed as recovered under the ESA. The rebound of any species is a gradual process that requires a long-term commitment and is dependent on many factors including direct threats, habitat, food availability, reproduction rate, and climate.
Does the Endangered Species Act protect only species in the US, or also species overseas?
Both – but in different ways
The current law protects species native to the US in several ways. As just a few examples, the law:
- Prohibits harming or killing endangered species;
- Bans the import and export of endangered species;
- Requires protection for land and water vital to species recovery (“critical habitat areas”)
- Necessitates the development and implementation of recovery plans for listed species.
Wildlife found in other countries is also protected by the ESA through the prohibition or regulation of trade in live animals or their parts and products across US borders and in interstate commerce. ESA also increases funding for their conservation.
Just one example – the red kangaroo was long hunted for its meat and hide, to the point that it was listed as endangered in 1974. In response, the ESA banned US imports of kangaroos and kangaroo-derived products from Australia, greatly aiding conservation efforts there. By 1995, scientists agreed the species had recovered.
Is the Endangered Species Act at risk of being eliminated?
Not entirely, but…
Only Congress can amend the ESA itself, but the Administration can amend the regulations that are used to implement the law, and the Trump administration announced amendments August 12, 2019 that will seriously undermine the effectiveness of the ESA and in turn put many species at risk.
The changes to the ESA regulations include no automatic prohibitions on the harming or killing, import or export of threatened species listed in the future. They also take away the ability to designate critical habitat necessary for the recovery of listed species. The Administration’s amendments will also decrease science-based decision-making while increasing political and economic influence over ESA listings.
If the goal of the ESA is to increase population size of a given species, these changes will only make recovery of listed species much more difficult.
Why would anyone want to weaken the Endangered Species Act?
Saving wildlife can be costly (but so can losing it)
For more than 20 years, opponents of the ESA have sought to weaken it, largely because of the restrictions it places on land use.
Yet a key part of the Act’s success lies in its flexibility, including voluntary agreements with landowners to conserve and recover species onto their lands. These positive collaborations address both species and landowner needs and allow for flexibility in ESA implementation.
As an example, under the ESA, the US has worked with 18 individual landowners to reintroduce populations of the black-footed ferret. The species, once believed to be extinct, now numbers in the hundreds with increased habitat and a greater chance of survival.
Which species are threatened by the changes to the Endangered Species Act?
Giraffes, monarch butterflies, polar bears and many more.
Species from the Americas to Asia, but mainly those native to the United States, could be impacted by the changes. The changes will mean weakened protections for future listed species, less scientific oversight, changes to critical habitat designations, and more. The new rule will also make it more difficult to prepare for the anticipated threats that climate change will pose to America’s wildlife.
What can I do?
Use your voice
Reach out to your Members of Congress and tell them you strongly support the Endangered Species Act and oppose these efforts to weaken it or undermine the protections it provides to wildlife, including both native and non-native species.
