The new interpretation of the 1973 law "is not conservation," warned one critic. "It is a license to destroy habitat, disrupt migration, pollute ecosystems, and drive endangered species toward extinction."
Wildlife defenders continued to call out President Donald Trump on Thursday after The New York Times exposed his administration's latest attack on endangered species and the landmark law intended to protect them.
The Times reported late Wednesday that as the administration's rule rescinding the regulatory definition of "harm" under the Endangered Species Act took effect earlier this week, the US Fish and Wildlife Service (FWS) internally circulated a memo interpreting the ESA to mean that only the intentional killing or wounding of a protected species is illegal.
"This memorandum—and other recent Endangered Species Act regulatory rollbacks such as the rescission of the long-standing interpretation of 'harm'—make clear that the Trump administration has declared an all-out war on America's wildlife," said Andrew Bowman, president and CEO at Defenders of Wildlife.
"The administration's absurdly narrow statutory reinterpretation hamstrings the ESA's effectiveness and makes a mockery of our nation's half-century commitment to saving and recovering America’s imperiled wildlife," Bowman charged. "This reinterpretation flies in the face of the ESA's plain language and common sense, as well as Congress' intent more than 50 years ago in enacting the ESA to achieve the goal of protecting and fully recovering listed species."
Oceana vice president Beth Lowell highlighted that "the proposed changes to the Endangered Species Act will remove the core safeguards that have prevented the extinction of 99% of species protected under the act."
"Federally permitted activities that incidentally injure and kill endangered species currently need to take into account their unintended impacts on wildlife, including nesting beaches for sea turtles or North Atlantic mother and calf pairs as they swim to their feeding grounds," Lowell noted. "These changes upend the Endangered Species Act's balance of economic activity and needed protections, pushing species to the brink of extinction."
The US Department of the Interior, which oversees FWS, told The Hill that the memo "accurately reflects the US Fish and Wildlife Service's guidance for implementing the Endangered Species Act following the final rule rescinding the regulatory definition of 'harm.'"
"Under the guidance, the ESA's prohibition on 'take' continues to prohibit conduct including harassing, pursuing, hunting, shooting, wounding, killing, trapping, capturing or collecting protected wildlife," the department said.
Susan Holmes, executive director of the Endangered Species Coalition—which includes 475 member organizations and over half a million activists—argued that the new interpretation of the law "is not conservation. It is a license to destroy habitat, disrupt migration, pollute ecosystems, and drive endangered species toward extinction."
"The administration has already eliminated habitat protection for endangered species with its extreme ESA 'harm' rule. It is using the so-called 'God Squad' to exempt oil and gas drilling in the Gulf from the ESA, and is threatening to eliminate protections for wolves," she pointed out. "This coordinated effort aims to strip the ESA of its power."
"If the Trump administration has its way, piping plovers will lose the beaches where they nest," Holmes warned. "Salmon will be pushed closer to extinction by dams, pollution, water diversions, and destroyed habitat. Grizzly bears will lose the connected landscapes they need to survive as roads, energy development, logging, and other activities fragment their habitat. Rice's whale—the only whale to live only in American waters—will be lost forever."
The coalition leader added that "the Endangered Species Act is our most popular and effective wildlife law, with support from 84% of Americans. We must not accept the destruction of a law that has protected our natural heritage for generations. The ESA must be defended, strengthened, and fully enforced—not gutted by political appointees acting on behalf of powerful industries."
Humane World for Animals president and CEO Kitty Block and Sara Amundson, head of Humane World Action Fund, also cataloged the administration's various attacks on protected species—and drew attention to a clear pattern regarding "who stands to benefit from these continued assaults on one of America's most popular laws for animals."
"It's certainly not the average American," they wrote in a Thursday blog post. "Instead, the beneficiaries are the massive industries that profit from destroying vital habitat and the animals who depend on it for survival. Oil and gas companies and other developers that have to (horror of horrors!) apply for a permit when their activities [pose] a risk of killing animals with federal endangered species protections—such as North Atlantic right whales, gray wolves, and black-footed ferrets, to name just a few—could be handed a pass."
"If this reinterpretation takes effect, more endangered animals will surely die," the pair declared. "And we will all be worse off for it."
"What the administration is proposing to do is take all of the force out of what we have all understood the act to mean: Don't kill endangered species."
"Hmmmm.... I've done a lot of horrible things lately. What is another evil, cruel, nonsensical idea? Ya know, one that would have irreversible generational consequences?"
That's how University of Alberta professor Timothy Caulfield responded to The New York Times' Wednesday reporting that President Donald Trump's administration "is quietly moving to strip a core protection" of the Endangered Species Act (ESA), according to an internal memo obtained by the newspaper.
Signed by US Fish and Wildlife Service Director Brian Nesvik, the memo interprets the law to mean that only the intentional killing or wounding of a protected species is illegal. The Times explained that excluding accidental acts "would be a seismic shift," because "the killing of endangered animals almost always happens incidentally, in the course of economic activity."
The memo is dated September 14—the same day that another Trump administration attack on the ESA took effect. That legally contested earlier policy rescinds the regulatory definition of "harm" under the 1973 law so that extractive industries can degrade crucial habitats. When the move was announced in July, critics called it "a death knell for America’s wildlife."
The effort revealed by the Times goes even further. Andrew Mergen, a Harvard University law professor who previously supervised ESA litigation at the US Department of Justice, told the paper that "this is really an assault on the act like we've never seen before."
"What the administration is proposing to do is take all of the force out of what we have all understood the act to mean: Don't kill endangered species," he said. "What they seem to be saying in this document is, it doesn't matter if you killed an endangered species if you didn't mean to."
Brett Hartl, government affairs director at the Center for Biological Diversity, said in a statement that "this stabs at the very heart of the Endangered Species Act by giving federal approval to the killing of some of America's most beloved wildlife... The Trump administration is desperate to annihilate environmental protections, but this incredibly radical measure is both cruel and profoundly unlawful. Killing endangered wildlife is illegal, whether that's your purpose or not."
"If you chop down a tree full of endangered birds or race a huge ship through a pod of endangered whales, you should be held accountable for your destructive acts," Hartl added. "But this administration wants to give wildlife killers a 'Get out of jail free' card. Imposing new limitations on the entire definition of take is a flagrant and illegal attempt to rewrite the Endangered Species Act via unilateral fiat. This would drive imperiled species over the cliff to extinction."
Other opponents of the plan called it "pure evil," and blasted the "perpetual villainy" of Trump's second administration—which has continued an assault on the landmark law launched during the Republican's first presidential term. All of his previous attacks on the ESA have faced resistance from conservation organizations and many members of Congress.
The rule on harm has sparked not only legal challenges from advocacy groups and state attorneys general, but also legislative pushback. In late July, US Reps. Brian Fitzpatrick (R-Pa.) and Mike Quigley (D-Ill.), co-chairs of the Congressional Animal Protection Caucus, introduced the Safeguarding Endangered Species Act, to nullify the policy.
Then, last month, Democratic US Sens. Adam Schiff (Calif.) and Sheldon Whitehouse (RI) introduced a Congressional Review Act resolution that, if passed, would repeal the policy. As the rule took effect on Monday, a Schiff spokesperson told CNN that "the senators will look to force a vote in the coming weeks."

One conservation advocate said the impact of wolves on livestock pales in comparison to that of "recent trade agreements and the reality of ranching in the arid West under changing climate conditions."
Although President Donald Trump was surrounded by farmers and ranchers while signing a pair of beef-related executive orders in the Oval Office on Friday, some critics cast doubt on their effectiveness—plus highlighted how one proposal could prove lethal for protected wolves.
Trump is facing high beef prices and the looming midterm elections. After meeting with Brazilian billionaire Joesley Batista, a key shareholder for JBS, the world's largest meatpacker, the president last month paused tariffs on 300,000 metric tons of beef for 90 days to be sold at a discount. While signing the new orders on Friday, Trump signaled that the cheaper beef will be imported from Argentina, Brazil, and "a couple of other places."
Trump's latest orders are intended to appease the US cattle industry, which was angry about the August proclamation, by "cracking down on major meatpackers' dominance of the industry and seeking to implement new labeling standards," Politico explained. However, "it's not clear whether any of the steps announced Friday will assuage ranchers' concerns or have any impact in the short term, given that most of them would require regulatory changes or congressional action."
Food & Water Watch (FWW) food policy director Rebecca Wolf said in a statement that "President Trump is on an apology tour after his deal to flood US markets with foreign-imported beef—it's not working. Today's executive orders will do nothing to reverse the last two years of Trump's disastrous food policy."
"Under his watch, consumer beef prices are at record highs, and ranchers can't make ends meet, all while the multinational meat monopolies profit hand over fist," she stressed. FWW found last month that while JBS reported $131.7 billion in revenue and $2.4 billion in profit, and fellow industry giant Tyson reported $82.65 billion in revenue and $681 million in profit, "prices are up 23% for choice beef, 24.2% for ground beef, 24.7% for ground chuck, and 25.2% for chuck roast."
Wolf noted that "US agencies charged with protecting market competition sit on the sidelines, made toothless by Trump's reckless job cuts," pointing to thousands of staff reductions across the Agricultural Marketing Service, Department of Justice, the Federal Trade Commission, and threats to slash funding for the Department of Agriculture (USDA) Packers and Stockyards Division.
Since Congress repealed mandatory country-of-origin labeling (MCOOL) for beef and pork in 2015, FWW has been among those pushing for its restoration. Trump's order directs Secretary of Agriculture Brooke Rollins, in consultation with the United States Trade Representative Jamieson Greer, to "review all statutory and regulatory authorities that may permit the establishment" of MCOOL for beef products, then issue or amend regulations, as permitted by law, and develop legislative recommendations.

As a diverse coalition that includes FWW circulates a "Label Our Beef" petition, Wolf said Friday that "it is clearer than ever that Congress must heed popular demand and restore mandatory country-of-origin labeling to give American producers an even playing field. And Trump must put his money where his mouth is and fund antitrust and fair trade enforcement to truly help American families and ranchers."
While FWW declared that "Trump's beef executive orders won't help consumers or ranchers," Angela Huffman, president and CEO of Farm Action, was more diplomatic, welcoming the language on MCOOL, meat processing, and Packers and Stockyards Act enforcement.
"These actions show the administration is listening to problems farmers and ranchers have raised for years, and we appreciate that," Huffman said. "They move in the right direction, but stop short of the stronger reforms independent producers need."
Farm Action supports legislation to restore MCOOL for beef, as well as Packers and Stockyards Act enforcement, but has argued that the latter "should be paired with stronger producer protections" and urged USDA "to reverse its planned rescission of the Inclusive Competition and Market Integrity rule, which would protect producers against undue prejudice, unjust discrimination, retaliation, and deceptive practices."
As for the harm that Trump's orders could do, one directs Secretary of the Interior Doug Burgum to "make a determination as to whether the gray wolf and the Mexican wolf have met the recovery criteria for delisting or downlisting under the Endangered Species Act (ESA) and, if he determines that the recovery criteria has been met," begin the process to end protections.
In addition to working with other officials on a legislative recommendation to strip federal protections from wolves, Trump told Burgum to "engage with states to encourage them to delist gray wolves and Mexican wolves from any state-specific lists of protected species and to revise their standards" for killing the animals "to assist ranchers in combating predation."
During an exchange in the Oval Office, Trump falsely suggested that ranchers can now shoot protected wolves.

Kitty Block, president and CEO of Humane World for Animals, responded Friday that "the war on wolves needs to end, not escalate. They remain absent from much of their historic range and vulnerable to the same cruel trophy hunting, recreational trapping, bounties, and other relentless killing that nearly wiped them out of the lower 48 states. Rolling back federal protections now—or setting that process in motion—would jeopardize decades of recovery and open the door for brutal killing."
"Gray wolves are essential to healthy ecosystems, and decisions about their survival should be based on science, not political favors to farmers and ranchers whose livelihoods are threatened not by wolves but by tone-deaf global trade policies," she added.
Advocates at the Center for Biological Diversity, Grand Canyon Wolf Recovery Project, Sierra Club Grand Canyon Chapter, Western Watersheds Project, WildEarth Guardians, Wildlife for All, and Wolf Conservation Center also ripped the order's wolf language.
"This is a huge distraction to placate a handful of ranchers and make them believe that wolves are a greater threat than President Trump's own policies," said Greta Anderson, deputy director of Western Watersheds Project. "The impact of wolves on the livestock industry [pales] in comparison to the impacts of recent trade agreements and the reality of ranching in the arid West under changing climate conditions."
Claire Musser, executive director of the Grand Canyon Wolf Recovery Project, emphasized that "the Mexican gray wolf is not recovered simply because the population has grown... With just 317 wolves in the wild and a population still facing serious genetic challenges, weakening federal protections now would put decades of recovery work at risk. Decisions about the future of lobos must be based on the best available science and what these wolves need for long-term recovery, not political pressure."
Arguing the wolves "desperately need more care and less persecution," Michael Robinson, a senior conservation advocate at the Center for Biological Diversity, promised that "we’re prepared to prove in court that downlisting Mexican wolves and a steep increase in killings would not only be cruel but also deeply unwise and illegal."
You do not need to fire a shot to kill an animal and imperil its entire species’ existence—you only need to take away the place it lives. A Trump administration Endangered Species Act rollback would do just that.
There is a vision of this country that still exists to anyone who grew up near its wild places: manatees drifting beneath a dock, Florida leafwing butterflies fluttering through the wind, yellow-billed cuckoos migrating in the spring and fall. For generations of Americans, these were not rare sightings. They were proof that people and wildlife could share the same natural inheritance
That inheritance is now under direct threat, and the erosion is no longer incremental. It is accelerating at an unprecedented pace.
Earlier this month, the Trump administration formally rescinded the regulatory definition of "harm" under the Endangered Species Act (ESA)—a single word that has helped to protect this nation's imperiled wildlife for more than 50 years. For decades, "harm" was understood to include not just the direct killing or injuring of an endangered animal, but the destruction or degradation of the habitat that animal depends on to breed, feed, migrate, or shelter. That understanding was not a bureaucratic technicality. It was the legal recognition of a basic ecological truth: An animal cannot survive the loss of its home and its resources for daily living any more than a person can. Each of these species has a story that will end the same way without habitat protection: not a quick death by bullet but a slow death by a thousand cuts.
Remove that definition, and you remove the government's ability to regulate clear-cutting old growth forest filled with an endangered bird’s nesting sites, draining a wetland key for an endangered frog’s breeding, or dumping pollution into the lagoon where sea turtles and marine mammals graze. You do not need to fire a shot to kill an animal and imperil its entire species’ existence. You only need to take away the place it lives.
Habitat destruction is already the leading driver of species decline in the US, and this rollback removes one of the few legal tools available to slow it.
Congress enacted the ESA in 1973 with overwhelming bipartisan support, and Republican President Richard Nixon signed it, "to provide a means whereby the ecosystems upon which endangered species and threatened species depend may be conserved." In the more than five decades since, the ESA has prevented the extinction of an estimated 99% of the species placed under its protection—one of the most successful conservation records in the world.
Rescinding the definition of harm will eviscerate the ESA. And it does so under the pretense of streamlining obstacles to American economic growth, as if the nation's economy runs on oil, gas, logging, and mining alone. But our national economy—and our national welfare—are inextricably linked to healthy, thriving wildlife and habitats. Wildlife watching, for example, supports a $250.2 billion industry in the US. Commercial and recreational fisheries generate $319 billion in sales and sustain 2.1 million jobs. Hunting and fishing support $400 billion in annual economic value. And the ecosystem services nature provides for free—clean water, crop pollination, flood control, pest suppression—are valued at an estimated $5 trillion a year.
Habitat destruction is already the leading driver of species decline in the US, and this rollback removes one of the few legal tools available to slow it.
Consider the Florida manatee, listed as threatened under the ESA. Manatees lack blubber and cannot fully regulate their own body temperature; in winter, their survival depends on access to water near 72°F. Coastal development and polluted runoff have devastated the seagrass beds manatees depend on and degraded the natural springs that once kept them warm through the winter. More than half of Florida's manatees now survive only because they cluster near the artificial warm-water discharge of aging power plants. Without the harm definition, it will be exponentially harder to protect and restore their foraging and sheltering habitats they need to survive and recover.
The same pattern will repeat across the country. The North American wolverine depends on vanishing high-elevation snowpack at risk of being lost to development and expanding winter recreation. The whooping crane, one of the rarest birds in North America, needs undisturbed wetland corridors to complete its migration. In the Arctic National Wildlife Refuge, polar bears depend on undisturbed denning sites; seismic testing, vehicle traffic, and aircraft noise associated with oil exploration can cause mother bears to abandon their dens and cubs. For five decades, the ESA enabled economic activities in the habitats species need to survive and recover, with permitting guardrails to ensure adequate protections. Now that the administration has eliminated those guardrails, it’s open season for industry to sacrifice habitat—and the future of our imperiled wildlife species. Defenders of Wildlife, along with other conservation organizations, has already gone to federal court to challenge this unlawful action.
At the same time, we’re standing up to defend the ESA itself from anti-wildlife members of Congress who favor unfettered logging, mining, grazing, and drilling, no matter the cost to endangered animals—or to our irreplaceable natural heritage. One of the most effective actions concerned citizens can take right now is to call their representative and senators and oppose any effort to undermine this bedrock wildlife law.
We are closer than most people realize to losing the manatees in our canals, the whooping cranes in our wetlands, and the wolverines in our mountains. What remains to be seen is whether we act while there is still habitat left to save.
“In the midst of an extinction crisis," said one advocate, "the Trump administration is gutting protections to benefit industry interests."
“Yet again, the Trump administration has sold out our endangered wildlife to the highest bidder,” said one biodiversity advocate after the US Department of Interior, in a Friday news dump, issued two new policy changes that would weaken the Endangered Species Act and make it easier for corporate polluters to prioritize their own bottom lines over habitat protection.
The US Fish and Wildlife Service (FWS) rescinded a policy that has been known as the "blanket rule" since 1975, which has given threatened species the same protections from illegal killing, trapping, harassment, and other forms of "take" under the ESA, as species that are officially designated as endangered.
The rollback would apply to species that have been newly declared as threatened, including the Florida manatee, the Pygmy rabbit, the Aztec Gilia, and Clover's Cactus—which could now go for years without protections despite their habitat loss and declining populations.
“Today’s decision represents a profound failure by Interior Secretary [Doug] Burgum and his department, and it amounts to an utter abdication of the federal government’s responsibility to protect America’s wildlife," said Sara Amundson, president of the Humane World Action Fund. "The department’s role is to faithfully implement—and certainly not to dismantle—the Endangered Species Act.”
The other policy change will require the FWS to consider the economic impact on various industries of designating areas as "critical" habitats in order to protect threatened and endangered species. The agency has previously had discretion over whether to consider economics when making habitat protection decisions.
Under President Donald Trump's new rule, said the Center for Biological Diversity, the FWS will be forced "to accept at face value claims by corporations and landowners of economic impacts from designating critical habitat, which could greatly limit the amount and quality of habitat protected for imperiled wildlife."
“Trump is bending over backward for corporate polluters by ripping away the blanket that protects so many struggling wildlife species as well as the air we breathe, the water we drink, and the natural places where we seek peace of mind."
"The way this is written, a landowner could falsely claim they planned to build the next Disneyland on their property, so designating critical habitat would supposedly cost them tens of millions of dollars,” said Noah Greenwald, CBD's endangered species co-director. “This rule is clearly intended to prevent the protection of the wild places that endangered animals and plants need to survive. It’s a despicable move that cheapens the value of our most imperiled wildlife so corporations can make more money. Anyone can make outrageous claims about how much their property is worth, but that shouldn’t be taken as gospel.”
Advocacy groups said both policy changes amounted to giveaways to the logging, mining, drilling, and cattle ranching industries. The latter industry has long lobbied against land being designated as a critical habitat for the ‘I‘iwi bird in Hawaii, Clay Samford, an attorney with the environmental legal group Earthjustice, told The Washington Post.
“It’s part of this administration’s push to reduce protections for public lands and wildlife that are enjoyed by all Americans, in favor of narrow business interests,” Samford told the newspaper.
A senior attorney for the group, Elizabeth Forsyth, said in a statement that "the Trump administration is turning the law on its head by letting extractive industries dictate where critical habitat can be destroyed."
"This prioritization of industry interests over science is fundamentally at odds with the clear purpose of the Endangered Species Act," said Forsyth. "We won’t let this dangerous giveaway go unchallenged.”
There is currently a backlog of more than 500 species awaiting consideration for listing as threatened or endangered, and the rule changes, along with the Trump administration's 18% reduction in the FWS workforce, are expected to leave imperiled species waiting even longer for protections.
“In the midst of an extinction crisis, with hundreds of species like the Florida manatee and the wolverine desperately needing stronger protections for their habitats, the Trump administration is gutting protections to benefit industry interests," said Ryan Shannon, a senior attorney at Defenders of Wildlife. "Where we see our nation's irreplaceable wildlife, they see dollar signs. But our federal lands and waters, and the species they support, belong to all Americans, not to the logging, drilling, and mining industries that oppose all limits on maximizing their private profits.”
In a statement, Interior Secretary Doug Burgum asserted that the ESA has long been "weaponized to stop almost any new project in America, driving up costs for families, weakening our competitiveness, and undermining our national security,” continued Secretary Burgum.
He added that the endangered species list has "fallen short," with 97% of listed species remaining designated as endangered, and called for "species recovery and delisting."
But Defenders of Wildlife noted that the ESA "has succeeded in preventing extinction for 99% of listed species."
"Public support for protecting our native wildlife remains overwhelmingly high, with 84% of voters supporting the ESA, according to nationwide polling conducted by Defenders of Wildlife," said the group.
The rules announced on Friday came days after the Interior Department proposed a new rule under which management of threatened grizzly bears would be transferred from the federal government to the states, where Republican leaders have pushed to end protections for the species.
The administration also exempted oil and gas companies from having to protect endangered species in the Gulf of Mexico, and earlier this month changed the regulatory interpretation of the word "harm" in the ESA.
“These rules are a one-way ticket to extinction for our most imperiled animals and plants, from monarch butterflies to giraffes to alligator snapping turtles,” said Greenwald. “Trump is bending over backward for corporate polluters by ripping away the blanket that protects so many struggling wildlife species as well as the air we breathe, the water we drink, and the natural places where we seek peace of mind. This is the last thing we need in the middle of an extinction crisis, and we’ll fight it with everything we’ve got.”
"Grizzlies shouldn’t be killed at the whim of the livestock industry while it exploits our public lands for its own personal profit."
Conservationists warned on Tuesday that a new proposal by President Donald Trump's Interior Department would permit more killing of grizzly bears, which are a threatened species in the lower 48 states of the US.
The Interior Department's proposed rule would transfer management of grizzly bears from the federal government to states where Republican leaders have sought to strip the species of protections. Interior Secretary Doug Burgum announced the new proposal—with little specific detail—alongside Montana Gov. Greg Gianforte, Wyoming Gov. Mark Gordon, Idaho Gov. Brad Little, and Republican members of Congress.
Jenny Harbine, managing attorney for the Northern Rockies office at Earthjustice, said it is "extremely concerning that the Trump administration is seeking to hand over more management of the species to hostile Northern Rockies states."
"While we need to see the details of this proposal, it could put grizzly bears at greater risk at a time of record mortality for the species," said Harbine. "Anti-science political maneuvers should not be allowed to thwart grizzly bear recovery. If this proposal will further harm the species, we are prepared to take the administration to court."
Andrea Zaccardi of the Center for Biological Diversity said that with its new proposal, "the Trump administration is trying to make it easier to kill imperiled grizzly bears."
"Grizzlies shouldn’t be killed at the whim of the livestock industry while it exploits our public lands for its own personal profit," said Zaccardi. "The science is clear that grizzlies need full federal protection to recover, not a rule that will lead to more grizzly bear mortality. We’ll be reviewing the rule and considering next steps.”
Fewer than 2,000 individual grizzly bears remain in isolated populations in the lower 48 states.
The Interior Department said its new proposal wouldn't alter the bear's listing status under the Endangered Species Act, which the Trump administration is trying to weaken. Opponents of the new proposal cautioned that giving more management to GOP-controlled states could be disastrous for the species, rejecting Republican officials' claim that the bears have sufficiently recovered.
"This is a decision being made for political reasons, it is not based on science, in the best interest of the survival of the species, or in compliance with the requirements of the Endangered Species Act,” Greg LeDonne, Idaho director of Western Watersheds Project, said in a statement.
A coalition of conservation groups sued the Trump administration in federal court on Tuesday over its move to rescind the regulatory definition of "harm" in the Endangered Species Act so that extractive industries can degrade crucial habitats.
"Since 1973, the ESA has served as the nation's most effective conservation law, saving numerous imperiled species from extinction and moving them toward recovery," states the complaint, filed in the District of Washington state. It argues that the rescission "defies the text and purpose of the statute, 50 years of administrative policy, and US Supreme Court precedent."'
The coalition is made up of the Center for Biological Diversity, Columbia Riverkeeper, Conservation Law Foundation, Conservation Northwest, Friends of the Wild Swan, Oregon Wild, Sierra Club, Swan View Coalition, and WildEarth Guardians, and is represented by Earthjustice.
"Preventing harm to wildlife by protecting where they live, eat, and sleep is a basic foundation of the Endangered Species Act," said Earthjustice attorney Kristen Boyles in a statement, also stressing that the decision conflicts with not only the ESA but also decades of legal precedent. "Now more than ever, imperiled fish, birds, and wildlife need protection to survive and recover."
Ben Greuel, wildlife campaign manager at Sierra Club, warned that "without the habitat protections offered by the harm rule, countless species would be forced onto a path towards extinction."
For example, "roads built for logging and other human access destroy grizzly bear habitat and the bear's ability to safely use its habitat," said Swan View Coalition chair Keith Hammer. "Weakening the harm rule will allow industry to devastate the habitat grizzly bears and many other wildlife species depend on for their survival."
Noah Greenwald, endangered species co-director at the Center for Biological Diversity, pointed to not only grizzlies but also some of the other specific species that could be impacted by the administration's decision.
"It's beyond tragic that as the world's scientists warn us of an extinction crisis threatening to unravel our shared future, the Trump administration is yanking basic protections from our most endangered wildlife," Greenwald said. "There's just no way to protect endangered animals like spotted owls, Florida panthers, or grizzly bears without protecting the places they live."
In fact, as Oregon Wild staff attorney John Persell, noted, "habitat loss is the leading driver of extinction."
"This gutting of the Endangered Species Act is part of a broader assault on our bedrock environmental values," Persell also emphasized. "From public lands to wildlife to clean air and drinking water, the Trump administration is determined to waste, loot, and pollute America's natural heritage."
Separately, the group Defenders of Wildlife sent a letter to the departments of Commerce and the Interior about its intent to sue over the ESA rescission, which was published in the Federal Register on Tuesday by their respective agencies, the National Oceanic and Atmospheric Administration and the Fish and Wildlife Service.
"The law has been clear for decades," said Jane Davenport, senior attorney at Defenders of Wildlife. "Rescinding this definition is wholly out of bounds and misaligned with the vast majority of Americans who support protecting and recovering endangered species."
"We will use the full force of the law to fight back and prevent industry from unfettered destruction of critical forests, streams, deserts, oceans, and coastlines," Davenport pledged.
The rescission came just a day after President Donald Trump signed proclamations dramatically shrinking the size of two national monuments in Utah, Bears Ears and Grand Staircase-Escalante.
As with Trump's repeated attacks on the ESA, his targeting of the two monuments dates back to his first administration.
Taylor McKinnon, Southwest director at the Center for Biological Diversity, said Monday that "gutting Utah’s national monuments to enrich polluting extractive corporations shows Trump's extreme disdain for Americans' shared natural heritage. It's a national embarrassment. These monuments protect some of America's most iconic landscapes and rich biodiversity. We'll fight like hell to safeguard their future."
"If animals don’t have a place to live, they can’t live," said one critic.
President Donald Trump's administration on Friday paved the way for letting US corporations destroy the habitats of endangered species by rescinding a longtime interpretation of the Endangered Species Act.
As reported by The New York Times, the Interior Department and the Commerce Department announced that they were narrowing the law's definition of what constitutes harming endangered species.
Whereas the law has for decades been interpreted as protecting endangered animals' habitats from significant "modification or degradation," the administration said that offenders would have to directly injure or kill an endangered animal to be considered in violation of the law.
"The change could open the door for fossil fuel companies, agricultural interests, land developers, and others," wrote the Times, "to disturb or even destroy the habitats of vulnerable species."
The Endangered Species Act has been interpreted as protecting animals' habitats for decades, and that interpretation upheld by the US Supreme Court in 1995.
Environmental advocates expressed horror in response to the rule change, which they said would put endangered species at unprecedented risk.
Kristen Boyles, attorney for Earthjustice, vowed that the administration would face legal challenges for its rule change, which she said would jeopardize endangered animals' ability to "raise their young, or search for food."
"Let’s be clear: There is no support for the Trump Administration’s rule—no scientific support, no legal support, no public support," Boyles said. "We will see the Trump Administration in court."
Ben Greuel, wildlife campaign manager at the Sierra Club, called the rule changed "a direct attack on the foundation of the Endangered Species Act" that, if kept in place, would put species "on a path to extinction."
"This rule ignores that reality in an unlawful attempt to open the door for corporate polluters to degrade vitally important habitats, wildlife be damned," Greuel emphasized. "The Endangered Species Act is a bedrock law that must be followed."
Tara Zuardo, a senior campaigner at the Center for Biological Diversity, pointed out that "habitat destruction is the number one threat to endangered species," while calling the Trump administration's new policy "a death knell for America’s wildlife."
"If animals don’t have a place to live, they can’t live," Zuardo said. "Spotted owls, Atlantic salmon, Florida panthers, and thousands of other species need protections for the wild places where they make their homes."
Andrew Bowman, president and CEO of Defenders of Wildlife, accused the Trump administration of embracing an "erroneous and nonsensical interpretation" of the Endangered Species Act that he vowed to challenge in court.
"We intend to fight back with the full force of the law," said Bowman, "to defeat this attack and innumerable others by the administration on the statutes and regulations that protect America’s cherished wildlife."
“This morally bankrupt bill will only lead to dirtier air, more toxic water, and countless species shoved over the extinction cliff," said one wildlife defender.
Congressional Republicans on Wednesday approved an appropriations bill containing massive cuts to Environmental Protection Agency funding, more than 20 riders undermining the Endangered Species Act, and other provisions harmful to the environment and wildlife—while boosting mining on federal lands.
Republicans on the House Appropriations Committee advanced the fiscal year 2027 Interior, Environment, and Related Agencies funding bill, which slashes total expenditures for the EPA by 20% and reduces its enforcement budget by $169 million—or nearly half, compared to last year’s levels. GOP lawmakers claim the dramatic reduction in EPA funding "safeguards American taxpayer dollars."
The bill also cuts the US Fish and Wildlife Service's listing budget nearly in half, "effectively dismantling the program in charge of determining which animals and plants deserve protection under the Endangered Species Act," according to a letter sent by a coalition of 80 conservation groups to House Appropriations Committee Chair Tom Cole (R-Okla.) and Ranking Member Rosa DeLauro (D-Conn.).
"The legislation also contains a total of at least 21 anti-wildlife poison pill riders—the largest number of policy riders that has ever been included in the base bill in the history of the Endangered Species Act," the groups' letter notes. "These riders would cause irreparable harm by undoing decades of progress to stabilize and recover some of our most iconic species."
The riders include measures blocking or weakening protections for imperiled species including the greater sage-grouse, lesser prairie chicken, northern long-eared bat, northern spotted owl, Canada lynx, and seven species of freshwater mussels.
Provisions in the bill also prohibit the federal government from banning or restricting lead in ammunition or fishing gear, block the reintroduction of grizzly bears in the North Cascades and Bitterroot ecosystems, and revive Florida’s illegal wetland destruction permitting program that harms species, including the Florida panther and frosted flatwoods salamander.
The Center for Biological Diversity (CBD), one of the groups leading the letter to House Appropriations Committee leaders, noted Thursday that the legislation also codifies climate denialism into law "by exempting federal land management agencies from updating their plans when new information shows endangered species are being harmed or killed on public lands."
Meanwhile, the bill contains provisions intended to expand mining on federal lands, including reinstating certain mineral leases and limiting some land withdrawals.
"Instead of lowering the cost of living and confronting the climate crisis, House Republicans are raising utility bills and energy prices," the office of House Interior, Environment, and Related Agencies Subcommittee Ranking Member Chellie Pingree (D-Maine) said in a statement Wednesday.
"The legislation takes an aggressive anti-environment, pro-corporate polluter stance with cuts to the EPA and policy provisions that endanger public health and fail to confront the climate crisis," Pingree's office added. "The bill also guts resources for the arts and museums while failing to prevent the administration from misusing funds to build President [Donald] Trump’s Garden of Heroes and Triumphal Arch."
The Republicans’ spending bill for Interior + Environment is a disaster:🚨 20% cut to EPA🚨 Free passes to polluters🚨 Rollbacks on PFAS regulations🚨 Millions for Trump’s vanity projectsThey care more about the president’s ego than the health of people and our planet.We're in for a FIGHT.

Pingree's office said the bill:
Democrats offered amendments to the bill during full committee markup, including measures to remove all the poison pills from the legislation, promote renewable energy, ban coastal oil drilling in California and Florida, provide funding for environmental justice initiatives, and prevent the construction of Trump vanity projects including his White House ballroom and bunker. Republicans rejected all of the amendments.
"This bill is a gift to corporate polluters, who would poison our communities in pursuit of even greater profits," DeLauro said in a statement Wednesday. "It saddles cities, towns, and working families with higher utility bills. And it allows President Trump to continue raiding public funds to pay for his own vanity projects."
"At a time when the American people are struggling to make ends meet, this bill makes the problem worse," she added. "It does nothing to bring down costs, while allowing the billionaires and big corporations, who have profited by polluting our communities, to get even richer. Meanwhile, the air we breathe and the water we drink gets less and less safe.”
CBD director of government affairs Stephanie Kurose said Thursday that "it's a disgrace that House Republicans want to dismantle decades of environmental progress and hand polluters unprecedented power over the health of our communities, public lands, and wildlife."
“This morally bankrupt bill will only lead to dirtier air, more toxic water, and countless species shoved over the extinction cliff," Kurose added. "Future generations will pay the price for this staggering level of political irresponsibility.”
"At a time when we should be strengthening protections for species," said one advocate, "not weakening them, it’s clear there is growing opposition to efforts that put special interests ahead of science and conservation."
Republican leadership in the US House of Representatives planned to mark Earth Day with a "catastrophic" attack on the Endangered Species Act, but ultimately canceled Wednesday's vote at the last minute, a development celebrated by conservationists nationwide.
After reports of "problems" getting some Republicans to back the ESA Amendments Act and a procedural vote that "showed shaky support from party members," as The New York Times put it, the House adjourned without a final vote on the bill—which the newspaper called "an embarrassing setback" for Speaker Mike Johnson (R-La.).
While the lead sponsor, House Committee on Natural Resources Chair Bruce Westerman (R-Ark.), claimed that "we just have a few provisions we've got to work through on it, and hopefully in the next couple of weeks, we'll be able to vote on it," Stephanie Kurose, deputy director of government affairs at the Center for Biological Diversity, said that "this should be a wake-up call to Rep. Westerman that not even his own colleagues support his extreme attacks on wildlife."
"It's time for him to drop this failed crusade," Kurose declared. "Good riddance."
Other wildlife defenders joined Kurose in enthusiastically welcoming the blow to what Bradley Williams, the Sierra Club's deputy legislative director for wildlife and lands protection, called "extremely harmful legislation."
"We are encouraged to see that the House of Representatives has pulled this bill after outcry from Republicans and Democrats," Williams said in a statement. "By rejecting a bill that would have gutted protections for endangered and threatened species across the country, Congress is sending a clear message that protecting wildlife is a shared American value, not a partisan issue."
Jewel Tomasula, policy director for the Endangered Species Coalition, which has hundreds of member organizations, said that "given the more than 58,000 emails sent to elected officials, along with hundreds—if not thousands—of calls made in just the past few days, it is clear that the American people support the Endangered Species Act, understand its value, and want its protections for threatened and endangered wildlife to remain in place."
"This is a welcome sign that efforts to gut protections for imperiled species are not moving forward on Earth Day," Tomasula continued. "We're glad Congress is hearing their constituents' concerns about Westerman's harmful bill and taking pause to listen. For now, the important work to protect endangered species can continue. This Congress should leave the ESA alone."
Major #EarthDay win 🎉: H.R. 1897, aka the Endangered Species Act Amendments Act was just pulled from house floor consideration following outcry from both Republicans and Democrats who oppose the bill.

Sara Amundson, president of Humane World for Animals Action Fund, similarly said that "on Earth Day, pulling the House vote on the deeply flawed Endangered Species Act bill is a clarion call that legislators need to stop heeding their own leadership and start doing the will of their constituents."
"At a time when we should be strengthening protections for species like grizzly bears and sea turtles, not weakening them, it’s clear there is growing opposition to efforts that put special interests ahead of science and conservation," Amundson said. "We urge Congress to abandon this harmful proposal altogether and instead focus on upholding and strengthening the Endangered Species Act for future generations."
Defenders of Wildlife legislative director Mary Beth Beetham proclaimed that "now we can really celebrate Earth Day!"
"The public defeat of the Westerman bill is a direct result of sustained constituent pressure," she stressed. "Congress is finally listening to the majority of Americans who support the Endangered Species Act, rather than centering politics and money in its policy decisions."
"The decision to not advance the vote keeps current safeguards in place, which have protected 99% of species from extinction," Beetham added. "While there is still much more work to secure lasting protections for wildlife, today's outcome is a meaningful victory for conservation."
