As the U.S. continues to fight the spread of the emerald ash borer beetle (Agrilus planipennis), this Canadian Press article indicates that Canada has decided to accept the invasion as inevitable. The article notes that:
"The Canadian government's official position is that the technology and efforts available cannot stop the ash borer's march..."Whether that is a realistic assessment or not, it's certainly going to make things more difficult for states like Ohio and Michigan, both struggling to keep the emerald ash borer in check, and both sharing borders with Canada. You can read more about the U.S. ash borer invasion in previous ISW posts.
