Here are examples of the divergent view of trees over the years. Early on trees were condemned completely, but as the years went by their use became accepted, although their proper use was debated:

Trees are never a fair hazard if at all near the line of play, as a well-hit shot may be completely spoiled by catching the branches.~~1896
Macdonald
Trees in the course are a serious defect, and even when in close proximity prove a detriment.~~1906
I read much about ideal and classical courses; I used both terms when I dreamed of the National, but I should like to make this distinction—no course can be ideal which is laid out through trees. Trees foreshorten the perspective and the wind has not full play. To get the full exaltation playing the game of golf one should when passing from green to green as he gazes over the horizon have an limitable sense of eternity, suggesting contemplation and imagination. This does not mean that a classical course cannot be laid out where trees are or when there is not the Atlantic, the Pacific or the North Sea to contemplate; but there is a vast difference between the ideal and a classical course. Yale is classical; St.Andrews, the National Golf Links and the Lido, the Mid-Ocean are ideal.~~1928
S.Thompson
In clearing fairways, it is good to have an eye to the beautiful. Often it is possible, by clearing away undesirable and unnecessary trees on the margin of fairways, to open up a view of some attractive picture and frame it with foliage…Open areas may be demarked by the judicious grouping of trees, which may define the fairways or act as a screen to hide some undesirable feature. Often times the natural beauty of many of a golf course, which the average player assumes was always present, has been created by the skill of the engineer who can see opportunities for beauty in the rough woods, swamps or fields that mean nothing to the unskilled eye.~~1923
A.MacKenzie
There are many debatable questions regarding general principles which occur to me, such as the value of tree hazards. There are many fine golfers who unhesitantly condemn trees on a golf course, their argument being that there are no trees on an old sand dune course. This is so but, on the other hand, on a n inland course the only way, except at enormous expense of providing hazards as high as sand dunes, is by the use of trees in groups.
Most of the best inland courses owe their popularity to the grouping of trees. Groups of trees are the most effective way of preventing players reaching the green with their second shot after playing the drives in the wrong direction. No bunkers guarding the green seem to be able to prevent them doing so.
Trees should not usually be placed in a direct line with the hole, as they block the view too much. They make an excellent corner for a dog-leg. Firs, pines, cypress, silver birch and California oak make beautiful back grounds for greens, All these evergreens are suitable for a golf course, while on the other hand, deciduous trees make a mess and look out of place.
Playing down a fairway bordered by straight lines of trees is not only inartistic but make tedious and uninteresting golf. Many green committees ruin one’s handiwork by planting trees like rows of soldiers along the borders of the fairways. Alternative groupings of trees, planted irregularly, create most fascinating golf, and give players the opportunity of showing their skill and judgment in slicing, pulling round, or attempting to loft over them.~~1933
M.Behr
And it goes without saying that trees lined to hem in fairways are not only an insult to golf architecture, but the death warrant to the high art of natural landscape gardening, aside for the fact that, of all hazards, they are the most unfair.~~1952
HS.Colt
Trees are a fluky and obnoxious form of hazard, but they afford rather good protection, and if a clump of these exists as such a spot it might well be considered justifiable to leave it standing.
In cases where the ground is covered densely with trees, it is often possible to open up beautiful views by cutting down a little additional timber. In such cases it would be unwise merely to clear certain narrow lanes which are required for play. The “landscape” effect should also be studied, and although great care must be taken not to expose any unpleasant view in the process, every endeavor should be made to obtain a free and open effect. Swinley Forest, St.Georges Hill, and Stokes Poges may be cited as cases in which tree cutting has greatly improved the views, and in the case of the two first-mentioned clubs a great deal more felling has been done than would have been necessary from a purely golfing point of view.
On the other hand, where very few trees exist every effort should be made to retain them, and in every case the architect will note the quality of the timber with a view of retaining the finest specimens.~~1920
CH.Alison
If you have any planting to do, do it at the start. Trees take a long time to grow. It may be desirable to plant out the parking space and caddies shelter, and to mask roads, unsightly buildings or railways embankments. It is also desirable to to have trees near teeing grounds, and on any large, open space, provided that they will not block a desirable view.~~1921
T.Simpson
Trees and bushes add enormously to the decorative value of the landscape, but are for the most part unsatisfactory as obstacles.~~1950
AW.Tillinghast
Trees of the better sort, well shaped and really fine specimens, are admired and loved by the vast majority of people in all walks of life, everywhere. Those unfortunates, who remain cold and impassive in the presence of the nobles of the forest, have something wanting in their make-up something that would make them happier. I find the greatest joy of my profession in working among the trees, for I can not conceive an inland course without them.
Certainly some of the most notable and charming courses have been constructed on land which was more or less heavily timbered. Naturally many trees have been removed in the process of building….Usually the twisting of a fairway through timber brings to view prominently fine trees along the sides, which previously have been rather lost in a general tangle. And here may it be remarked that fairways should be rather irregular in shape and not like bowling-alleys extending through the woods…So must judgment be used in removing trees, to the end that every possible beauty be featured so long as it does not interfere with the sound play of the game. Certainly the necessity of lofting over a barrier of trees cannot be countenanced although this situation still exists in some sections of the country and naturally the course are of antiquated design. But play through woods should not be over done, It may be quite monotonous. Introduce just enough for variety.~~1932
D.Ross
As beautiful as trees are, and as fond as you and I are of them, we still mist not lose sight of the fact that there is a limited place for them in golf. We must not allow our sentiments to crowd out the real intent of a golf course, that of providing fair playing conditions. If it in any way interferes with the properly played stroke, I think the tree is an unfair hazard and should not be allowed to stand.
On the other hand, there is no need to ruthlessly cut down everything before us. If it can be arranged so that holes are slightly elbowed, trees can frequently be spared. On hot summer days they are most welcome, especially around tee boxes.
G.Thomas
While trees are generally considered poor hazards, nevertheless they may be properly utilized in some cases, but should not be used as carrying hazards. Rather adapt them as impssible carries which must be gone around, often giving reward for such play.
Trees and shrubbery beautify the course, and natural growth should never be cut down if it is possible to save it; but he who insists in preserving a tree where it spoils a shot should have nothing to say about golf course construction.
Generally speaking, adjacent fairways should be divided by rough and traps and the planting of trees; but on small tracks, where the holes must be close together, this ofttimes impossible, and is a very strong additional objection to fairways which are close together.~~1927
W.Flynn
The pleasantest type of course is one where the holes are segregated, that is where the hole you happen to be playng is well apart from the others. In order to have this kind of course it is necessary to secure property that is already wooded or to do considerable planting of trees.
The old idea was to have golf courses as free of trees as possible. This notion, no doubt, was imported from Scotland because when golf was first taken up in the United States we knew very little about the game and modeled our courses on those of the Scotch which were, for the most part, built along the seashore where there were no trees.
It is impossible to conceive that the "Canny Scots" would have denuded their courses of trees if there had been any there originally.
Today the old ideas have been discarded and the prevailing belief is that trees, most emphatically, have a fixed place on a golf course. This is true for many reasons:
First-Because there are few, if any, sites available that are devoid of trees and it is a very costly operation to cut them down and remove them. Second-Trees add beauty to a golf course forming picturesque backgrounds and delightful vistas. Third-Their shade is most refreshing on a hot summer day. Fourth-They are of great practical value in segregating the various holes.~~1927
