Actually there is more going on than we know according to researchers. I saw a study once that said trees give off some kind of warning signal in the form of pheromones or something when there is an approaching fire or a predator eating their leaves damaging their limbs.
What good it does them I don't know as obviously they can't move! Maybe there is a chemical change to help them resist damage?
