uhh, i see where you are coming from. If there is a lovely tree and someone decides to hack into it and rip out some bark then wow you're a moron, you have no respect for the tree then your dmt trip should be dark. Im sure the spirit of the tree wouldnt appreciate that.
On the other hand though, If you're on the pursuit of DMT then you dont have much of a choice when it comes to hurting a tree. Just dont be so rough. I would take a branch neatly and remove the bark from the branch. Even in the amazon when they hack away at the Vine(Ayahuasca) and the DMT containing leaves from Chacruna trees. The shaman are more in touch with the plants than anyone on this forum, and they are slicing into these plants. Also, they dont take the leaves/vines from plants less than about 7-8 years old. The older the better.
Point being though, if you're going to get the bark then do it with respect for the plant. Otherwise you just dont deserve the DMT which the plant is storing in its bark and leaves and roots for us,im guessing, for the use of consciousness expansion.
