Tree Planting

Our Master Tree Plan specifies that when planting trees, only those native to Michigan can be used. We find high quality specimen trees with a DBH of 4 - 6 inches. DBH refers to Diameter Breast Height and is an industry term frequently used when measuring trees. Trees larger than 6 inches DBH can be transplanted, but their mortality rate increases.

One tree that adapts well to our soils is the Swamp White Oak, or Quercus bicolor. Bicolor means “two-colored” and refers to the contrasting green upper and white lower leaf surfaces. A mature Swamp White will reach about 65 feet tall and about the same width.

It helps that it is relatively easy to transplant and nice specimens can be found at many nurseries. Swamp White Oaks have moderate fall color, at maturity are great shade trees in summer and their bark is appealing in winter.

We have planted several Swamp Whites’ on the South Course, most notably on #14 fairway. One of these was planted a little too close to the fairway several years ago, so this January we brought in a large (100 inch) tree spade and moved it to the woodlot on #15, shown above.

Other Oaks – Red and Chinkapin – will be planted this May. Their specific location has not been decided.
