On a windy September morning in the desert outside Las Vegas, a field biologist knelt beside a burrow and listened for the faint scratch of a tortoise that federal law has guarded for decades. A few hundred miles away, in a Washington office, lawyers were reading a new instruction that could change what that protection means in practice. According to reporting on a Sept. 14 Fish and Wildlife Service memorandum, accidental harm would no longer count as an illegal take. The endangered species take rule, long treated as a brake on careless destruction, is being read more narrowly than many biologists expected.
A memorandum that redraws a familiar line
The Boston Globe reported that an Interior Department memo would narrow how the Fish and Wildlife Service applies the Endangered Species Act ban on take. In ordinary speech, take sounds like a deliberate act: a shot fired, a trap set, a nest torn out by hand. In federal wildlife law it has meant more. For years the prohibition has reached killing, wounding, harassing, and significant damage to habitat that actually injures a listed animal, even when the person who caused the damage never intended the result.
The new reading, as described in that coverage, pulls accidental harm outside the ban. Officials have not published a full public rule with the memo, and the text circulating among advocates is still being parsed. What is already clear is the direction. If accident is no longer enough, a great deal of ordinary land use moves from a legal question to a matter of discretion.
What take has meant for half a century
Congress passed the Endangered Species Act in 1973 after a run of extinctions that embarrassed a country that thought of itself as careful with its remaining wild places. Section 9 made it unlawful to take listed animals. Later rules defined harm to include habitat changes that kill or injure wildlife by impairing essential behavior such as breeding, feeding, or sheltering. The Supreme Court upheld that habitat based reading in 1995, in a case brought by landowners and logging interests who said the government had stretched a simple word too far.
That history matters because the endangered species take rule did not arrive as a slogan. It arrived as a statute, a regulation, and a court decision that told agencies they could treat destruction of a nest site, a spawning reach, or a desert burrow as more than a side effect. Generations of permits, consultations, and settlement agreements were built on that understanding. A memo cannot erase a statute, but it can tell field staff to stop treating certain facts as violations.
Accidental harm and the ordinary work of the land
Most animals protected by the Act are not shot. They are hit by mowers, crushed under tires, poisoned by runoff, or left without the cover they need after a field is cleared in the wrong season. A power line crew might top a tree that holds a listed bat. A county road crew might grade a shoulder where a rare snake is denning. A farmer might disk a fallow strip that, unknown to him, holds the only breeding pool for a tiny fish after a wet spring.
Under the older practice, those facts could trigger a conversation with federal biologists, a timing restriction, or a permit that allowed the work if the landowner reduced the risk. Under a reading that excuses accidental harm, the same facts may produce a shrug. Intent becomes the hinge. Proving that someone meant to hurt a rare animal is far harder than proving that the animal was hurt.
Why habitat sits at the center of the fight
Biologists have argued for decades that habitat loss, not malice, is the main reason species slide toward extinction. A wolf can be poached and the crime is obvious. A butterfly disappears because the only hillside with its host plant is paved, and nobody in the cab of the grader could name the insect. The legal concept of harm was written to catch that second story, the one without a villain and with a body count that shows up years later in a survey.
If accidental harm drops out of take, habitat injury does not vanish from the Act. Other sections still require federal agencies to consult before they fund or permit projects that may jeopardize a listed species. Those consultations can still slow a dam, a highway, or a timber sale on public land. What weakens is the direct prohibition that reaches private land, where most remaining habitat for many listed species actually sits. That is the practical difference between a law that follows the animal and a law that follows only the federal dollar.
How conservation lawyers are likely to answer
Advocacy groups are already treating the memo as an invitation to sue. Their argument is straightforward. A memorandum is not a substitute for the public process that Congress requires when an agency changes a binding rule. If staff are told to ignore a regulation that is still on the books, challengers will say the agency is acting in secret and beyond its authority. They will also say the reading conflicts with the Supreme Court decision that accepted habitat harm as take.
Whether those suits succeed depends on how firmly the memo binds the people who write citations and deny permits. Courts often refuse to review internal advice until it produces a concrete decision. A landowner denied a permit, or a group shown that enforcement has stopped, will have a cleaner case than a press release. Expect months of procedural skirmishing before any judge reaches the meaning of the word harm.
The case from ranches, roads, and power lines
Property groups and some rural officials have wanted this narrowing for years. They describe the older practice as a trap. A person can follow every state rule, hire a surveyor, and still face federal liability because a listed bird nested in a tree slated for removal. They say permits are slow, expensive, and written in a language that small operators cannot afford to translate. In their telling, a law aimed at extinction has become a tax on ordinary work.
That complaint is not invented. Consultations drag. Biological opinions arrive late. A family that owns a few hundred acres can feel cornered by a statute drafted for continent scale problems. The question is whether the remedy is to excuse accidents, or to make the permit path faster and clearer while keeping the duty not to destroy the last places a species can live. The memo chooses the first path. It does not, on the public record so far, build the second.
States, tribes, and uneven capacity
Wildlife management in this country is a braid of authorities. States hold the primary police power over resident game. Tribes manage species on trust land under their own codes and treaties. The federal Act steps in when a species is listed, often because state tools were not enough. If federal staff stop treating accidental harm as take, the burden shifts back to those other governments, and they are not equally ready.
Some states have strong endangered species statutes of their own. Others have little more than a list and a biologist shared across several counties. Tribal nations vary just as widely, and many already carry restoration work that federal budgets only partly fund. A national narrowing that assumes someone else will fill the gap will land hardest where that someone else is a single warden with a truck and a radio.
Scientists warn about slow losses
Extinction is rarely a single headline. It is a series of local disappearances that look, in any one township, like bad luck. A population of frogs fails to breed after three dry years and a new drainage ditch. A shorebird colony shifts and then vanishes after repeated disturbance that nobody logged as intentional. Researchers who track these patterns say the law’s value was that it forced a pause before the last local loss, not after.
They also note a measurement problem. If agencies stop recording accidental harm as a legal event, the paperwork that scientists use to see trends may thin out. Fewer incident reports, fewer required surveys, fewer conditions written into permits. The animals will still die. The ledger will just get quieter. That quiet is a policy choice, and it will make later arguments about recovery harder to ground in numbers.
Courts have been here before
This is not the first attempt to tug the Act toward a narrower reading of harm. Earlier administrations rewrote regulations on critical habitat, on the weight given to economic costs, and on how agencies forecast the future of a species. Several of those changes were frozen, rewritten again, or struck down. The pattern is familiar: a political appointee moves fast with a memo or an interim rule, career staff implement what they can, and judges decide years later whether the move respected the statute.
Landowners caught in the middle hate that cycle. So do field biologists who rewrite guidance twice in one career. Stability is part of fairness. A person deciding whether to plant, pave, or restore a creek should know which acts the government will treat as violations. A memo that floats above the printed rule, without a clear public comment period, trades one uncertainty for another. The endangered species take rule becomes a matter of which supervisor is on duty, not which sentence is in the Code of Federal Regulations.
What the public can still see
Readers far from desert burrows still have a stake. Listed species anchor fisheries, pollinate crops, and signal whether rivers and forests are holding together. The Act has also been a bargaining tool. Developers accept seasonal limits and set aside acres because the alternative is a violation. If accidental harm is no longer a violation, some of those bargains lose their legal spine. Voluntary deals will continue where a company wants a reputation for care. They will fade where the only pressure was the statute.
Citizens can still comment when formal rules are proposed, still ask state wildlife agencies what they will enforce, and still read the consultation documents that federal projects must release. None of that replaces a clear national standard. It does keep the argument in public, which is where a law this consequential belongs.
The months ahead
The immediate test is operational. Will field offices decline cases they would have opened last spring? Will permit writers strike conditions that existed to prevent accidents? Will the Justice Department stop bringing the small civil cases that taught landowners the boundaries? Those choices will show whether the memo is advice or a new endangered species take rule in everything but name.
Congress could answer by amending the statute, clarifying that harm includes accidents, or by doing the opposite and writing intent into the ban. Neither vote is assured. Until then, the practical law will be whatever enforcement pattern survives the first lawsuits. A tortoise in a burrow does not know the difference between a memo and a statute. The people who share its ground will learn it soon enough, in the permits they are no longer asked to seek and in the losses nobody is required to count.
