The Endangered Species Act Is Under Attack. But How Much Trouble Is It In?

Politicians are asking for major changes to the law鈥攁nd even an outright repeal. Here's how the ESA could take a hit and everything that's at stake.

Forty-four years ago, the most important wildlife-conservation law in American history passed the U.S. Senate with a vote of . 鈥淣othing is more priceless and more worthy of preservation than the rich array of animal life with which our country has been blessed,鈥 President Richard Nixon said after ratifying the Endangered Species Act (ESA).

But in the decades since, the ESA has come under attack. Industries have labeled it as radical and abusive. Congress has to weaken it. Flare-ups between states and federal agencies have led to over its scope. The assault听has escalated to the point that now听14 attorneys general the Trump administration to revise the law. Meanwhile, long-time ESA-nemesis Rep. Bob Bishop [R-UT] to repeal it.

An outright repeal, of course, would be extremely challenging. Even if every Republican senator voted to scrap the law, they would need to sway eight Democrats to overcome . Given that the ESA is still popular among the masses鈥攁 2015 survey shows that of Americans support it to some degree鈥攖hat isn鈥檛 likely.

Still, there are听several other听tactics opponents听could take to undermine听the act.听One听probable, time-tested approach听is : for example, repealing the provision that allows citizens to file lawsuits against the government or other private persons for failing to list or protect a species, or on expensive projects, such as the spent in 2014听to save the steelhead trout.

Tangling up individual species protections is another possibility. If passed, ,听a new bill introduced to Congress by Rep. Pete Olson [R-TX],听would remove the 12-month deadline for making listing decisions, allowing officials to let petitions听fester for years. It would also give the Interior or Commerce Departments the power to reject a listing because of economic fallout. The Greater Sage-Grouse has been a major target for anti-ESA legislation, too. Two identical bills in the and are proposing that states take over federally managed grouse lands, while also blocking the bird from landing on the endangered species list until 2027.

Of all the options, starving the ESA of funding might be the most straightforward way to hurt it. Federal spending on endangered species declined by nearly $90 million between and , and Congress could demand further cuts. The overall budget can鈥檛 be filibustered, and supporters of the ESA likely won鈥檛 expend much political capital trying to stop small-scale changes.

鈥淪upport for the act is broad but not very deep,"听says Patrick Parenteau, a professor and former director of the Vermont Law School鈥檚 Environmental Center. "It鈥檚 hard to find a champion with clout.鈥 So far, Rep. Raul Grijalva [D-AZ]听has been one of the few politicians who've stood up for the act.

The most important ESA provision鈥攁nd the one that seems to most perturb Bishop鈥攊s the broad prohibition of 鈥渢ake.鈥 This includes a long list of actions that could lead to the death or harassment of a protected species. Making too much noise, if the racket interrupts breeding, is one extreme example. Bishop and his peers argue that the bulk of these infractions are trivial, criticizing the built-in fines and jail time as a 鈥溾 approach to conservation.

Yet the law is more constructive and profound than critics give it credit for. The conservation work done through the ESA is collaborative, and prosecutions of landowners are 鈥.鈥 The take policies coax landowners to work with the U.S. Fish and Wildlife Service (USFWS) on a recovery plan. Once a species鈥 numbers rebound and it鈥檚 taken off the list, business can go back to usual. 听

These are the types of alliances that helped bring the Whooping Crane back from the brink. The federal government spends each year trying to protect the endangered bird and its habitat. A permitting process limits heavy construction projects during the cranes鈥 migratory seasons; on popular stopover sites, water and other natural features are preserved to boost the birds鈥 survival rates. The government also pays certain landowners to make major changes to their properties, and issues for projects that improve habitats along migration routes. It鈥檚 a cooperative, negotiated, and well-compensated system鈥攏ot the jackbooted scenario that Bishop wants to portray. And it鈥檚 effective: The Whooping Crane population went from , to nearly 600 individuals today.

If the program's funds are slashed,听however, such听progress could easily be halted鈥攊f not reversed.听鈥淲e鈥檝e invested so much in saving the species鈥攖o lose even 10 to 15 individuals a year would be devastating,鈥 says Steve Holmer, vice president of policy at the American Bird Conservancy.

Species on the margins of the law could be in jeopardy as well. The Lesser Prairie-Chicken, one of the ESA鈥檚 most debated-over birds, is one example. The quirky, foot-long fowl used to . But lately, conversion of prairie to farmland and fossil-fuel production the species鈥 32,000 remaining members to small, fragmented areas in five states.

There鈥檚 little dispute over what the birds need: Large connected swaths of 听allow different populations to mix and breed, buoying prairie-chicken survival overall. Rather, the disagreement lies in who鈥檚 responsible for developing and enforcing a recovery plan. The federal government, the states, oil and farm interests, and conservation groups are locked in an 21-year battle over the bird鈥檚听conservation status. The species was listed as threatened in 2014, then delisted by a judge who called the ruling 鈥渁rbitrary and capricious鈥濃攁 victory for the oil and gas groups that sued USFWS. The agency is currently reviewing the listing again, with a decision expected by this summer.

Regardless of the听verdict, the mere existence of the ESA is crucial to the prairie-chicken. Private听landowners鈥攚ho hold 95 percent of the bird鈥檚 native range鈥攁re to keep it out of harm鈥檚 way. The reason? They know that if they fail, the federal government will swoop in. Without that fear driving them, the pressure to save the bird would disappear.

In its relatively short and contentious听lifetime, the ESA has helped dozens of species dodge extinction. In fact, it has a 99 percent success rate in keeping wildlife from going extinct; of the 100 or so bird species,听many are . But the act is only as strong and effective as we allow it to be.听Whether it's听by one well-aimed blow听or a thousand tiny cuts, any dismantling听of the ESA听could reverse decades of hard-earned success, and deprive future species from the protections they need to survive.听

Correction: The story previously reported that 80 percent of birds protected by the ESA are in recovery mode. That听statistic only applies to birds in the Northeastern United States and has therefore been removed.
