If a Bat Dies When a Tree Falls, Does It Count?
If a tree comes down with an endangered bat roosting inside, the bat is just as dead whether anyone meant to kill it or not.
That seems pretty straightforward.
The U.S. Fish and Wildlife Service is now taking a different view.
In a September 14 directive to agency staff, Director Brian Nesvik wrote that cutting down a tree would not count as illegally “taking” the protected bats inside unless the tree was felled for the purpose of killing or capturing them. In other words, if the goal was clearing land and the dead bats were collateral damage, the agency’s new position is that it may not be a prohibited take under the Endangered Species Act.
And that is a much bigger deal than one hypothetical tree full of bats.
A Little ESA Translation
The word ‘take’ does some heavy lifting in the Endangered Species Act.
It does not just mean capturing an animal. The law defines “take” to include actions such as harming, wounding, and killing protected wildlife. For decades, federal wildlife protections have also recognized something most of us understand intuitively: you can hurt an animal by destroying the place it needs to survive. In 1995, the U.S. Supreme Court upheld the government’s interpretation that significant habitat modification could qualify as “harm” when it actually kills or injures protected wildlife.
That matters because endangered animals are rarely living in some neat little bubble labeled WILDLIFE: DO NOT DISTURB.
They are in trees that get logged. Wetlands that get drained. Rivers crossed by roads and pipelines. Coastlines busy with boats. Fields, forests, and other places people also want to use.
For years, one of the practical effects of the Endangered Species Act has been making people stop and ask: Are protected animals here, and what can we do to keep from killing them?
Sometimes the answer means changing when work happens. Moving part of a project. Checking trees before cutting them. Creating a conservation plan. Getting an incidental-take permit.
Not exactly radical stuff. Mostly: look before you bulldoze.
Intent Is a Strange Line to Draw
This new directive focuses heavily on whether a person was intentionally acting against a particular animal.
That creates a pretty strange distinction.
Imagine someone knows protected bats are roosting in a tree and cuts it down anyway because they want the land cleared. They did not cut the tree because they wanted dead bats. Dead bats were simply a foreseeable consequence of getting the tree out of the way.
From the bat’s side of things, this distinction is admittedly not very useful.
And from a conservation standpoint, intent has never been the only thing that matters. Habitat loss is one of the biggest pressures facing wildlife precisely because people usually are not trying to kill animals. We are building houses, harvesting timber, constructing roads, mining, farming, and otherwise changing landscapes for human purposes.
The wildlife loss happens along the way.
If the legal question becomes primarily “Were you trying to kill the animal?” instead of “Could you reasonably avoid killing it?” there is less incentive to look first, plan around wildlife or reduce predictable harm.
This Didn’t Come Out of Nowhere
The September directive follows another major change made this summer.
Federal wildlife agencies finalized a rule removing the longstanding regulatory definition of “harm” that included certain habitat modifications that kill or injure protected wildlife. The administration argues that the change better matches the language Congress originally put into the Endangered Species Act. Conservation organizations and a coalition of states have challenged that interpretation in court.
So this is not settled law carved in stone.
The September memo tells Fish and Wildlife Service employees how the agency currently intends to enforce the law. It does not change the text Congress passed, and it does not erase the 1995 Supreme Court decision. Courts will almost certainly have more to say about where the line actually sits.
In the meantime, though, agency guidance matters. It influences which cases are investigated, when permits are expected, and how much pressure there is on projects to prevent harm before it happens.
Bottom Line: The Bat Still Dies
I keep coming back to the tree because it makes all of the legal language much easier to see.
There is a tree.
There are endangered bats inside.
Someone knows they are there and cuts the tree down anyway.
The bats die.
We can spend a lot of time debating what the person intended. We probably will.
But conservation has never worked particularly well when we pretend consequences disappear because they were inconvenient rather than deliberate.
Wildlife does not experience our intentions.
It experiences what we do.
