Invaders: Emerald Ash Borer

This insect will wreck wholesale damage once it reaches the Canadian Prairies. Green and black ash account for high percentages of trees in the landscape and in local woodlands.
In a city like Saskatoon, Sask., where few large broadleaf trees are hardy and Fraxinus and Ulmus american account for 90% of the mature urban forest, the havoc will be almost uncomprehensible. Dutch Elm disease is at the doorstep, EAB only a few years away.

This is going to be very expensive if us Minnesotans don't do something. It doesn't help that they are so cheap. What are the latest reports on how far they've expanded into Wisconsin?

The closest discovery of emerald ash borer has been in Victory, WI. That's approximately one mile from the Minnesota border. According to MDA officials on April 23, 2009, evidence suggests the Victory infestation has been in place for several years. Because the beetle can move several miles a year on its own, a precautionary quarantine has been put in place for Houston County, MN. At this time, no EAB has been found in Minnesota.
