Science Friday · Surveying wildlife along Lewis and Clark's route, 220 years later · 28 May 2026 podcast

There didn't used to be those.

And we did it at just the nick of time because, you know, we almost lost the American bison.

We almost lost the black-footed ferret.

There were a lot of species, even the bald eagle.

We saw 15 bald eagles in one day on the Missouri River.

And, you know, that's a species that almost went to extinction, was put on the Endangered Species Act, another conservation measure that we invented.

And it has now recovered and is now off the list.

It's more complicated.

And there are, you know, so that's kind of the more recent stories, right?

And we're seeing some of that as well.

We just drove through Western North Dakota where there's just oil infrastructure everywhere.

And that's definitely hurting the wildlife, right?

The populations are not able to live in that area that has so many oil rigs all over the place, so many roads, no habitat.

You know, we're moving next to the American Prairie Reserve, which, you know, we have almost no American prairie left because so much of it has been converted to

to farmland and ranch land, and trying to find a way to have room for bison, for example, our national mammal, is still a big challenge.

So what we saw 100 years ago were challenges of too much hunting, overuse, unsustainable use.

What we're seeing now is less that, because we've learned how to manage that, and our society has agreed to follow these rules and find sustainable use of wildlife.

Somehow we stopped the destruction and we put a pause on it and we invested public money in research to invent wildlife management.

We invested public money in protecting areas, parks, national parks, national forests.

You know, those are things that we really created in America in the early 1900s and mid 1900s.
