With the emergence of substantial Emerald Ash Borer infestation areas in Plymouth and other area cities, the Plymouth Park Maintenance & Forestry Division will increase preemptive removal of ash trees in wooded areas adjacent to city-owned trails.
The ash trees will be removed to slow the spread of EAB by reducing available wood for infestations to expand. Trees are also removed out of concern for public safety – as ash trees die from EAB, they can become falling hazards along trails and in recreation areas.
What Residents may Notice
Ash trees are inventoried and marked with orange dots to make identification easier in winter. Currently, there are more than 900 ash trees identified for removal. The city will plant seedlings and disperse seeds in appropriate locations to supplement the natural regeneration of the impacted wooded areas. Tentative removal sites include the areas of Mission Hills, Rolling Hills, Four Seasons and Maple Creek parks, as well as Parkers Lake.
What Should Residents Do?
Residents should continue to monitor private ash trees and develop a plan. High-value ash trees may be treated, and less valuable trees should be removed prior to infestation. Once infested, treatment is usually ineffective in preserving the tree and as the tree dries out, it becomes more hazardous to remove in a safe manner.
About EAB
Confirmed in Plymouth in 2015, Emerald Ash Borer is a small, invasive insect that infects ash trees and spreads quickly, typically killing a majority of ash trees in its path. The city has been preparing for the arrival of EAB since 2012 and has applied an ongoing, preventative treatment cycle on a variety of public ash trees in city boulevards and parks that are a minimum of 15 inches in diameter and in good health.
There are two options for property owners with ashtrees – begin a course of treatment immediately, or plan for the tree to be removed. For those who choose the former, treatment is typically necessary for the rest of the tree’s life. For more information, visit plymouthmn.gov/eab.
