Sorry, amazing how something that seemed so good, seems so bad after a couple of decades.
There are trees on the course that are being marked with green ribbon. These trees are Ash trees or genus Fraxinus. The Emerald Ash Borer (EAB) is currently a problem in our area. We have a plan for dealing with this pest, and the first part of the plan is identification of the Ash trees on the property.
