The Emerald Ash Borer (EAB) is an invasive beetle from Asia. It was first discovered in the United States during the summer of 2002 near Detroit, Michigan. EAB has quickly become one of the most destructive and costly forest insects in urban forest history.
Emerald ash borer is causing a devastating ecological event throughout the Twin Cities. More than one in five metro area trees is an ash tree. Losing this many trees is comparable to a natural disaster, having both a large environmental and economic impact.
If you live in a Minnesota city, there is a good chance you have an ash tree. Ash trees are a common native tree species and were also frequently planted as landscape or boulevard trees. Pictures on how to ID an ash tree can found here.
Take action before removal is your only option! If you have an ash tree, you have the choice to protect or remove your tree(s). We recommend that residents consider protecting large, well-placed, healthy private ash trees as part of an EAB treatment program.
As of April 2019, Rainbow Treecare has partnered with over 25 cities and neighborhoods throughout the Twin Cities to treat public trees in parks and along boulevards. These partnerships also include a city-wide discount to private property owners. Through this discount program, property owners can treat their ash trees at a reduced price.
