My home club, Stafford CC, in Stafford, NY, has a 1921 Travis designed course on land that contained very few trees, a line of Black Cherry that cut across the course, but was largely removed during course construction; a couple of White Oak; and some apple trees. In 1927, the club's Board of Governors employed a noted landscape architect, Harold L Olmsted, to oversee a tree planting program that ran into the early '30s. He scattered several oaks around the course, many elms, ash, and silver maples. The Dutch Elm disease, of the late '50s, wiped out most of the silver maples. Unfortunately, in some areas, those trees were replaced, with a variety of trees. In the early '60s, several varieties of pines/spruce trees were planted throughout the course.
All of that has come home to roost. Silver Maples have become a major problem, many of the Oaks are in positions where they limit sun and air to greens, etc. Fortunately, most everyone is on board with the major tree removal that is underway.
