Let's talk history, at least in the USA. During the 60's and 70's, wall to wall green maintained turf was the ideal largely inspired by color tv's Masters coverage. It was often referred to as the Masters Syndrome. In 1976, Paul Voykin, who was in the midst of a 48 year tenure as Superintendent at Briarwood CC, published an article in the Greens' Section Record and gave a talk to the superintendents association entitle Over Grooming Is Overspending. PV suggested that maintaining out of the way areas was unnecessary and costly. He also suggested that significant benefits relating to beauty and the environment would follow. If you look at the article, the dollars involved compared to today are laughably small.
PV's talk did not result in a rush to naturalizing golf courses but over time the sheer logic of his position has taken hold. Certainly there are instances where the practice is taken to the extreme. I concede that significant forced carries over impenetrable gunk should be avoided. There is also a level of skill, often developed via trial and error, in developing the appropriate density of naturalized areas. At Briarwood we learned that in planting fescue, we needed to use less seed per square foot than was recommended to achieve the desired look and feel. But I suggest that when properly done, naturalized areas provide the benefits that Paul Voykin touted more than 50 years ago. They save significant amounts of money. They add beauty to the course and make it appear less artificial. They create a better habitat for wildlife. As we have added natural areas, more small animals have a place to live. This attracts other animals and birds so that,for example, we now have nesting Hawks living on our grounds. . I concede that there are a few more delays looking for potentially lost balls, although not nearly to the degree suggested by Jeff. But I suggest that, properly placed, these areas add far more than they take away through occasional delays caused by extremely errant shots. I know that our membership feels the same.
