Emerald Ash Borer
For several years, homeowners and landscapers in Southeast Michigan were concerned about the loss of their ash trees to “ash yellows,” thinking that the problem was due to a combination of disease, drought, pollution, acid rain, and poor soils. The trees exhibited a top-down dieback, yellowing leaves, dense sprouting from roots and trunks (“epicormic shoots”), and other signs of tree stress typical of ash decline or other native phloem borers such as two-lined chestnut borer. One-third to one-half of the affected ash trees’ branches died within a year, and most of the canopy was dead within two years.
