TimespanAs the EAB Invasion Wave moves through your area trees die in a predictable manner. The table below helps you predict where you are in a 12 year cycle that describes the number of trees that have become hazardous due to EAB injury and require limb or entire tree removal. The second line describes the number of years until all trees are in this state. The third line describes the likelihood of detection.
