Which trees, bushes and plants to leave when cutting trees

"Cut down with an axe or flourishing, about cutting trees, building etc
I was reading Gary Snyder's poetry book Turtle Island and it has also a poem of burning undergrowth where trees have been cut: It says that indians used to burn bushes each year but the fire did not reach the treetops. In such fires lots of insects die, propably bird nests too and maybe mice etc, at least they lose their homes and lots of undergrowth dies. Is defending such fires like the deeds of academical people often are: One's lack of skills leaves some essential big part without protection, or many such big sreas, and on the other hand some single things and meaningfulnesses get cultivated. It has some of the mentality of cutting down all the trees on some area: a single theoretical perspective walked over a fine forest patch. In choices one would need more skill and more skills in balancing, and more understanding of the effects of one's own approach, for example about the effects of tiredness.
A success is something like that now I cultivate this which I know to be ages old good things, I cultivate something with lots of strenght to live, something unified and fractureless, something strong in itself, something which carries things to well, something that renews itself, grows new life.
It does not come from coming with a square head,kind of saying aha, such and such was meant to be made here, so I will do such.  Instead one needs to be aware of one's approach. The forest patch and it's edges, single seed trees and lush beautiful trees or bushes form an whole that curves like a path, and which brings different things to mind when one looks at it's different parts. If I will leave this group of young trees and plants here, will it bring a fractureless, pleasant atmosphere into the area. If I will leave that young tree at the edge uncut, will it suggest that I will then leave to the edge, twinding like a path, some other young trees or nicely fitting together other trees or plants. When I walk here now, on a good luck day of mine, as fractureless, does there lift to my mind a picture of a beautiful landscape: some big trees, some bush like smaller trees or a group of plants, landforms curving like a twinding path fascinatingly, what would be a nice landscape, good to wander in, made witha good understanding, good for life and for animals, growing trees and the like?"
