Its easy to dismiss trees as inanimate features of the landscape, but these living, breathing organisms arent as stoic as they appear. Trees, it turns out, make all kinds of noises as they grow and respond to their environment. Happy, regularly growing trees sound different from drought stressed trees. Now, a team of researchers from Grenoble University in France is trying to pick out these cries for help amidst all the normal tree white noise in order to provide better, more targeted aid to trees suffering from drought, according to National Geographic.
In the case of drought, trees undergoing stress form tiny bubbles inside their trunks, NatGeo explains, which causes a unique ultrasonic noise.
Imagine using a straw to slurp the last few drops from the bottom of your glass: You have to increase the pressure even more. In drought-stricken trees, this increased pressure can cause the water column to break, allowing dissolved air to form bubbles that block water flow.
These breaks are called cavitations, and they can eventually lead to a trees demise, so researchers and managers are interested in identifying warning signs that indicate that a tree needs emergency watering.

Dang, that title got botched pretty badly....
I thought Tress normally made those noises.
Guess its just me.
I think they’re barking up the wrong tree.
And the wind cries, Mary.
That’s a girl tree, dude! Get your mind out of the gutter.
So do screaming ‘fetuses’ being murdered by the pro life butchers..but libs don’t care about that. Sick the priorities of these people.
Yes means yes and oh G** means YES and no means yes except for when it means help. Right.
I can’t here them over the sound of my Stihl Chainsaw.
I hope the Admin Mods do not change or correct the title.
Because this thread will go down in history with the 'al baby' "stuned beeber" thread from back in 2004.
Oh, please. All liberal crap like this originated in France, and I see they're still cranking it out. Stress a rock and it makes noise, too. But it's not a cry for help... Sheesh.
I like the screams they make when I fell them cut them up. Split them and chuck the pieces into my airtight stove. Then after I close the airtight door the screams subside and all I hear is pops and crackles. ; )~
My birch is a stripper. The sounds.....
Just as the 3000 year old mummy looked better than Hillary, so does that tree.
Yep, it’s botched something fierce, and no, I’m not intoxicated. Just inexplicable. I’m thinking sleep deprivation, though.
“Well, how would you like to have someone come along and pick something off of you?”
