Seen many dead trees lately? Mainly ashes? In North America? With bark damage and shiny green beetles laughing maliciously nearby?
The emerald ash borer (EAB) came to North America sometimes in the last 20-40 years and has been devastating populations of green ash trees (Fraxinus pennsylvanica), white ash (Fraxinus americana), black ash (Fraxinus nigra), and to a lesser extent, blue ash (Fraxinus quadrangulata). Unfortunately, these trees, especially green ash are the most commonly planted trees in many cities, sometimes making up as much as 40% of a cities total tree-cover, making it easy for EAB to spread and wipe out whole populations. Not to mention their important roles in many North American forests. Join me today to learn more about this issue, why it's a problem, and what's being done about it.
