It's amazing how even a few trees can make a difference.
My course has almost no trees, having been built on farmland. Most of the trees are on the course boundary.
About a month ago, some trees were cleared behind the 14th tee that were damaged during Hurricane Sandy. All of a sudden, the back tee that was always dark and "hidden" is out in the open and getting plenty of light. Turf health has improved, the the tee is much more playable because it simply looks a lot better.
My point is don't overlook trees that are out of bounds as potential candidates for removal.
