Cutting down ash trees in Door County has become more dangerous with many trees drying out because of a recent non-native insect infestation. The arrival of the emerald ash borer in Door County in 2014 has caused problems ever since the insect was discovered. The insects eat their way through the tissues underneath the tree. This can cause problems when attempting to cut down the tree later, as the tunnels made by EAB dry the tree out and can result in an unpredictable cut that could cause harm to people or property. Bill McNee, a forest health specialist with the Wisconsin Department of Natural Resources, said the best way to avoid any problems is to treat the uninfected trees first instead of waiting until it is too late.

McNee noted that if the decision is made to treat and protect certain trees, it would create a monetary loss for the customer. He also suggested treatments be made every year.
