The emerald ash borer (EAB) is native to northeastern Asia, but since 2002 it has established itself as one of the most devastating invasive species in the United States. Emerald ash borers lay their eggs in ash trees, where their larvae create galleries that cut off the trees’ supply of vital nutrients, causing them to deteriorate and die. This is particularly problematic in Minnesota, where black ash trees are very common.
When one hears the word “emerald”, you would automatically think it has to do with some priceless jewel. In the case of Emerald Ash Borer, also known as EAB, it signifies the destruction of one of our valuable natural resources.
EAB is a beetle so named for its wing covering that has an emerald appearance. They attack ash trees by laying eggs in tiny spaces created by the bark. When the eggs develop into larvae, they burrow into the tree’s trunk leading to what is known as emerald ash borer infestation.
Minnesota is lucky to be home to such a diverse collection of trees. Statehood began in 1858, but many of our old-growth forests have been around for even longer. These forests have trees dating back over 200 years, according to the Minnesota Department of Natural Resources (DNR). These massive and historic trees can even be seen speckled throughout neighborhoods, public parks, and walking trails. Read more
Minnesota has a large reputation for being a rugged, northern state filled with thousands of lakes and millions of trees. Especially in residential areas, trees provide important habitats for various animals, produce oxygen for the environment and provide shade during the hot summer days.
