Trees don't suffer any subjective pain, nor are they able to think. They are not sentient.
"No I wouldn’t, but maybe that’s where I’m still limited in my own
thinking! To me thinking and information processing are two different
constructs. I have to be careful here since this is really bordering on
the philosophical, but I think purposeful thinking necessitates a highly
developed brain and autonoetic,
or at least noetic, consciousness. Plants exhibit elements of anoetic
consciousness which doesn’t include, in my understanding, the ability to
think. Just as a plant can’t suffer subjective pain in the absence of a brain, I also don’t think that it thinks."
