Separation is ok in golf (ala Pine Valley) but nothing can compare to open vistas on the golf course. My take is that open visas allow you to tie the hole you're on with other holes on the property. You can let your mind wander a little and check out awesome views of the land. The better the land the more you want to see ... That doesn’t mean a landscape devoid of trees but smartly planted trees of high quality whose placement is well thought out.
If the land you’re on is great ... why cover it up with trees and add separation?? I liken it to a beautiful woman whose is bundled up with 6 layers of clothes on... the more layers you peel off the better the view ... it’s really no different in golf landscapes. If you have a river, stream, natural rise/fall, pond, or lake open the landscape so they can be viewed and enjoyed.
In almost every instance when golf courses remove trees to open up vistas, it really, truly enhances the golf course. The problem arises that those types of tree removals are the most difficult to get approval for because they don't necessarily affect fine turf areas. But that being said, once members/golfers see the after affects of a few of these types of tree removals, it’s hard to deny its long lasting benefits. . .
