An individual tree has roots and, of course, it doesnt move. But trees, as a species, do move over time. They migrate in response to environmental challenges, especially climate change. Surprisingly, they dont all go to the Poles, where it is cooler. As it turns out, more of them head west, where it is getting wetter.
Sure, some species, such as evergreens, are heading to the Poles to escape the heat. But others, like certain oaks and maple, are going west in search of rain. For the most part, tree migrations are moisture related, said Songlin Fei, associate professor at Purdues Universitys department of forestry and natural resources, who has studied this phenomenon in recent years. Precipitation has a stronger near-term impact on species shift than temperature.
Fei analyzed the movement of 86 tree species from across the Eastern United States between 1980 and 2015 using using field data obtained from the U.S. Forest Service. He found that 73 percent of tree species shifted to the west, while 62 percent moved poleward.
To be clear, the study focused only on the eastern half the country, meaning tree species didnt move to, for example, California, Oregon, or Washington. In fact, the transition was gradual. Species, on average, moved about 10 miles per decade, or about one county during the study period, Fei said.

If your going to multi post...
You need to do it in trees...not twos
Tree migration is due to landscaping designs bringing in trees from one geographic location to another.........Not a nature driven search for water or whatever.
Then the gal is screaming "Screw the trees - I'm getting lucky ..."
The other two gals are praying for another guy and the guy with the headband - well I'm not going to say what I think he's doing but he may be gay.
Pretty sure that's what was going on. ;-)
Stay
Just a little bit longer
Trees, trees, trees, trees, trees
Tell me you’re going to
Now, your daddy don’t mind
And your mommy don’t mind
If we have another dance
Just one more
One more time
Or maybe people are planting them in new locations.
;-)
I hope the guy on the ground is laying his face in poison ivy. (said as I have the remnant of a festering patch of it on my arm)
That makes no sense. It’s drier in the west.
Coconuts abandon home when very young
yep - I thought the same thing about face-down guy. That’s probably the closest he’s ever been able to get his hand to a pretty girl’s “hoo-hah”. (ha!)
Then I read the following poison ivy remark and laughed yet again!
My trees out back told me they are thinking of moving out west too. I said enjoy:)
Well played sir!
Not only can they walk...
You should see the little bastards run...
I’ve noticed that white oaks don’t care for black oaks, and force them to migrate to the back of the forest.
I’m old enough now where I can call bull**** on liberal crap like this. First time I ever saw Saguaro cactuses was in 1960. You would first encounter them on Black Canyon Highway (I-17) when you dropped off of Sunset Point. In 1970, the “global coolers” told us that they Saguaro were “migrating” south to escape the cold. In the 1970s, you encountered them in the same exact spot. 1980s and 1990s, THE SAME PLACE. Y2K! The same place! 2010. Yup, same place. 2018. Same place. Somebody B boosh*ttin’.
