The impacts of nonnative invasive species have been devastating to forests and other ecosystems worldwide. The remnants in front of you are from a white ash that was killed by the emerald ash borer (EAB), a nonnative invasive insect. Like most invasive species, in Asia, its native habitat, EAB poses little threat to ash trees because it is naturally controlled by controlled by other insects, diseases, and natural host tree defenses. However, ash trees in Europe and North America do not have these protections. Since EAB was introduced in Michigan in 2002, it has it has killed hundreds of millions of ash trees. EAB larvae feed on the living tissue directly below the bark, leaving tunnels, which over time starves ash trees of resources needed survive.
