That's a cute little tree. be kind of hard to hurt your self in except for cutting your self in the tree. Why not just cut the branches on the side with all the weight on it with your pole saw from the ground. Just rip cut them so they hang on the tree, then after one side is down finish your cut, that way you won't crush the bushes. Then just put a line as high as you can, tie a truckers hitch, make your face cut, tighten up the truckers hitch as tight as you can, have a wedge or two ready just in case and fall it. Or even cut it high with a big face cut, and let it fall on the bushes. If it stays on the stump, it won't hurt them to bad you can't clean them up.
