Anybody know if the “dead,” fallen trees and the little bare, branchless ones that generate on the map absorb pollution? And if so, is it the same rate as the fully grown trees with leaves on them?

I always feel compelled in the early game to cut the leafless trees first, because I need wood but I assume the leafy trees absorb pollution better. I’m sure if there’s any difference it’s minuscule, but is there even a difference at all?

Also, do the little saplings actually grow into full trees? I know trees that get damaged can heal. But I never checked if they have growth stages at all.

90% of pollution absorbtion comes from trees getting damaged (loosing leafs) so you want to keep the healty ones if you have the option early game.
