It's not a perfect system. Rob says there's uncertainty in the climate model projections and uncertainty in the climate variables they're using to match space and uncertainty in how far they transfer the seeds. I mean, this hasn't really been done before, so it's not like they have a ton of things to compare it to.
But the idea is that if you live in a place that has Douglas firs and gets really cold winters now but is projected to get milder winters in the future…
and then I live in a place that also has Douglas firs, but already gets milder winters right now, then hypothetically, I could send you some of the seeds from Douglas fir trees where I live, the ones that already adapted to milder winters, so you could plant them. Does that make sense? Totally.
Right. Except if you were robbed, then you'd actually send the seeds to Dorena Genetic Resource Center and then they would sprout the seeds and plant them and grow the baby seedlings first.
So they're moving the population around, but still staying within the overall species range. That way, they're hoping to avoid the risk of introducing new, potentially invasive species, while still benefiting from the natural, individual adaptations that trees already have.
sense of how it's all going? They only started planting sites last year, but right now the plan is to do a first-year measurement after each site is planted and then to check in on each site every five years.
Rob says he's committed to leading it for at least the next 20 years, and he's hopeful it could continue for even longer because the Forest Service has a history of really committing to long-term growth experiments. like the Doug for Heredity study that launched back in 1912.
I mean, Emily, some of the trees that were planted as part of the Doug for Heredity study are still around, right? It's been over a century. And there's still stuff that we're learning from these same trees.
No, totally. And if these trees make it, they'll need to survive all of these different climate scenarios all along the way. Which, again, kind of scary, kind of impressive, kind of optimistic.

Thank you.
You're listening to Shortwave from NPR. Hey, shortwavers. Emily Kwong here with shortwave producer Hannah Chin.
But what are they doing? Why are they roving these rows with cameras of all things? Are we just setting ourselves up to be replaced by robo-farmers?
Are you one of the half of Americans who say money management is part of their self-care routine? Or one of the 41% of young adults who think financial well-being means having multiple streams of income? On It's Been a Minute, I'm investigating how young people are turning to OnlyFans, sports betting, and Klarna to stretch every last dollar.
That's all month long on the It's Been a Minute podcast from NPR. You're listening to the NPR Network. Live from NPR News, I'm Laxmi Singh.
Han, I am obsessed with robots. I actually dressed up as Eve for Halloween with my partner Duncan as Wally. That's so cute. And I really want to know all about Wally's cousins. This robot is so cute. Let's first talk about the problem the robot is solving for.
Okay, what is causing this mildew? Isn't mildew usually related to dampness?
Oh, like these infections are not related to each other.
That's a sad state for these poor plants. Okay.
That is so pernicious.
