A few things I can think of... hole 11 (the new one) can always be cleaned up. Take branches and sticks far away from the fairway. Any other wooded type holes probably need similar treatment, but 11 is probably most in need.
Hole 5 needs the large logs in the first wooded area (near the tee) to be moved to the left, making 'walls'. This might require a lot more man power, or some machinery though.
Some holes might have weeds in them, hole 10 comes to mind. These can be taken down with a trimmer/weed whacker.
