You may have noticed some changes happening around the grounds of the government campus buildings in Southeast Rochester. Bugs are taking over, and we're not talking mosquitos this time! The confirmed presence of the Emerald Ash Borer has prompted Olmsted County Parks to join efforts with Rochester City Parks and begin the process to eliminate this problem beetle. Nearly 110 Ash trees reside on the county campus.
The view is going to open a bit over the next month as many Ash trees are taken down, sent through a chipper and added to the Olmsted County compost piles on site. Trees that are already considered hazardous along with a percentage of Ash trees in large clusters will be in this scheduled removal. This kicks off a long-term plan to replant a wider variety of trees as well as treatment for some of the existing Ash trees that will remain on the campus. The Ash trees that remain will get an insecticide treatment which will kill off the present infestation and prevent against further spread of the beetle, allowing the trees that are still healthy to prolong their life. As trees are removed, young trees of varying species will be planted over the course of 5-10 years to help prevent the future problem of all trees dying or needing replacement at the same age.
