I recently purchased a wooded lot in the UP of Michigan and would like to plant trees along the highway to act as a buffer. This main purpose of this buffer would be to block sound, but it would also ideally block sight and act as somewhat of barrier for the kids. Any suggestions on what trees to plant would be greatly appreciated (as of right now I am thinking douglas firs etc).

Also, I would like to thin some of the trees off the lot. Which trees should I leave and which should I trim out (from what I remember, birch, pines and maples comprise most of the trees on the lot)? Any specific trees/bushes I should plant to attract deer and other wildlife? Thanks!
