And then, of course, you can cut off parts of trees to avoid cutting it entirely, in case you want to use part of the wood of a tree but not the entire tree.
How tall should the tree regrow? I don\'t think it... realistic... for a tree to suddenly sprout up from... a stump. Once a tree is dead, its dead. It is not something that sprouts up again once you cut off a part of it. At leasts, according to my knowledge/ignorance. You might have to start planting trees, enchant it to grow faster and taller, and then cut it down, or climb up it.
Another bad thing that can happen is the tree may have things inside, or you damage the wood too badly for the wood to be of any \'good\' quality.
