Trees - They have no right being on a golf course - so John, answer is No.
This is my opinion and that of Old Tom.
Perhaps we both in our time consider that a links course is the first choice for a golfer. Having said that, I played at Beaufort Park Golf course near Hastings, for many years in the 70’s. Just about every fairway was lined with trees, but never used as a hazard, that was left to the nature of the course which was built over the hills like Rome. Not a great course, but a rollercoaster of one with fun to be had, depending on your mood.
Trees, they attract wild life and the likes and should only be placed out of the way. Line the course with them, by all means, help improve the environment by having tree lined fairways, but never, never use them as a hazard. The other issue with trees on a course relates to their thirst and how the ground around them is severely affected, both in drought and wet conditions.
To rely on trees as a form of a hazard, shows the limitation of a designer. IMHO it reflects the inability to use ones imagination and raises questions
along the lines of ‘is this the correct career choice?’ and ‘would landscape gardening be more appropriate?’
However, I expect some may not agree.
