Tree Infections and invasive pests

Incidences of emerald ash borer relating to ash trees in North America are on the rise. This non-native exotic beetle is native to Asia, and is believed to have been unknowingly carried to North America on cargo ships and airplanes. Since first being spotted near Detroit in 2002, this pest has killed tens of millions of ash trees in Michigan, alone. For dead or dying trees, sadly, tree removal or letting trees rot are the only options. More than 20 states and Canadian provinces have lost hundreds of millions more ash trees to this pest. Ohio is one of the hardest-hit states. While adult emerald ash borers are relatively harmless, their larvae are lethal to ash trees. They feed on ash trees’ inner bark preventing them from transporting water and nutrients.
