Implementation details: The City of Hutchinson employs a full-time arborist
Starting in 2014, the City of Hutchinson started implementing a forestry management plan in response to the threat of emerald ash borer. The plan, better known as the Forestry Diversification Project, consists of several small tree removal and replacement projects that will occur on an annual basis, increasing tree species diversity to reduce the risk of loss to our ash tree population. Here is a general project overview:
1.Projects will target ash trees in the publicly-owned right-of-way;
2.Priority project areas – areas in which a project will occur – have ash populations above 20% and are areas of high visibility, i.e.) parks, main thoroughfares, playgrounds, etc.;
3.All publicly-owned, ROW ash trees have been identified and inventoried. Project areas that are found to have more than 20% ash will have a certain percentage of ash trees removed and replaced with an alternative species known to do well in Hutchinson. Trees found to be in poor condition will be prioritized for removal;
4.Projects will occur on an annual basis until the desired ash population has been reached, or until emerald ash borer arrives in Hutchinson, whichever comes first.

Emerald Ash Borer in the City of New Brighton
In November of 2013, the Minnesota Department of Agriculture confirmed the discovery of ash trees infested with emerald ash borers (EAB) on residential property in the City of New Brighton. EAB is a serious invasive pest. Consequently, a quarantine has been placed on Ramsey County to slow the spread of EAB to other areas.
The City of New Brighton began treating boulevard and selected park ash trees for EAB in 2010 and continues to follow the recommended treatment guidelines.
For the benefit of the residents, the City has taken preventive steps to establish criteria for contractors treating EAB. The criteria will make sure residents will receive services from a competent contractor at a fair price. For example, each contractor has been in business a minimum of 5 years and has agreed to a per-tree charge of no more than $10 per diameter inch, with a $100 minimum charge.
The City’s website provides specific information on what services the contractor has agreed to and what the property owner can expect from the contractor. Visit www.newbrightonmn.gov and click on the following links: Departments/ Parks and Recreation/ Forestry/ Emerald Ash Borer Treatment Tree Contractors.
In addition, citizens can access informational article’s regarding EAB on the City’s website. Residents can also obtain a brief history of EAB, how it spreads, symptoms of EAB, what to look for in your ash trees, options for treating trees and how the City is responding to save ash trees by watching a video on the City’s website.
Residents who suspect they or a neighbor has EAB should call the Minnesota Department of Agriculture at (651) 201-6684 (press 2) and follow the voice prompts. Also, if you want to become a Forest Pest First Detector go to University of Minnesota website: http://www.myminnesotawoods.umn.edu/forest-pest-first-detector/

Since then, forestry team members are actively treating boulevard ash trees with products to prevent the infestation of Emerald Ash Borer consistent with the City's Emerald Ash Borer Management Plan. Team members also periodically treat the 300+ oak trees at Augsburg Park to control the native pest, the two-lined chestnut borer.
