What exactly does a tree do once it’s been notified of danger? “Oh shit, I better tree even harder

Acacia trees increase tannin level in their leaves. Giraffes don't like the bitterness and stop eating it.

The emitted ethylene will only move with the wind. Giraffes counter that by moving upwind, targeting trees that have not been 'warned'.

I see someone's read The Hidden Life of Trees!

I'm not sure about the trees but a bunch of plants release ethylene as a stress response (too much water, not enough water, too much salt, etc), causing fruit to ripen faster likely increasing their chances at successfully reproducing. You can suspend ripening in apples for instance by blocking the ethylene receptors.

Maybe it can like store a little energy or water or smth to try to have a better shot at survival?

Edit: after a quick googling, they do this when an animal starts eating their leaves. Trees that have been warned will increase tannin production to toxic levels, making their leaves less than palatable.

I did-ish, and I'm not even ADHD but I'm probably something on the spectrum and my thing is random plant facts, bitches.

I did know that, yes.
And I also searched for the usual coping mechanisms too, just to see what other homies are doing.

Also it's just stupid old tech that wind thing, why not use the internet (ie the mycelium network)? It has worked for others for 100s of millions years.

Warn the other uncles someone is eating him?
That's nice of him.

The other uncles don't move, just become more bitter.
