M City of Mows VhON What is Emerald Ash Borer? 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. EAB larvae feed on the inner bark of ash trees which disrupts the trees ability to transport water and nutri- ents. Once an ash tree is infested, it has almost zero chance of survival. The only way to protect yourtree is with treatment. EAB populations can grow exponentially each year because the beetle has few natural predators and our ash trees have limited natural defenses. When EAB is not managed, annual ash tree deaths can quickly over- whelm the resources required to remove dead and dying trees. healthy larvaeL-n the grown thousands of new ring beetles emerge A healthy ash tree will transport water through the current year's growth ring. The larvae of the beetles eat the growth rings under the bark. A heavily infested tree can no longer transport water and the top dies_ The beetles will move on to the next ash tree. Is EAB in My City? EAB was confirmed in Mounds View, Spring of 2018! Like most Minnesota cities, Mounds View has an abundance of ash trees growing on public and private property. A 2010 DNR survey found more than 5,400 ash trees in Mounds View. It is estimated that over 30 percent of trees in the Twin Cities area are ash trees. Rainbow Treecare What are My Choices if I have an Ash Tree? If you have an ash tree, now is the time to decide what to do. Ash trees can be protected or removed. Mounds View is encouraging residents to treat large, well -placed, healthy private ash trees as part of an EAB treatment program. Considerations for Treatment: • Tree size greater than 10" in diameter. • Tree is not competing with other trees or infrastructure. • Tree shows no more than 30% of canopy decline if infestation is suspected. Treating an ash tree is more cost effective than removal and replacement, plus maintains the tree benefits and value of a mature tree to your property! Treatment LOW CDC - BIG Gain! VS - Removal HIGH Cost 'L B 10 Loss! Protecting your ash tree for 20 years is less than the average cost to remove and replace it. EAB larvae damage on ash tree.
