City to remove Cork trees from 4th Street due to invasive classification
[Duluth, MN] City of Duluth Park Maintenance crews will be removing male Amur Cork trees from 4th Street due to the tree being classified as invasive. A total of 18 trees will be removed in the coming weeks. The majority of the impacted trees were planted during the St. Louis County and City of Duluth 4th Street Reconstruction Project. The project reconstructed two miles of 4th Street for the first time in 30 years and replaced the water, gas, and sewer lines, some of which were more than 100 years old.
Various kinds of trees were planted in the boulevards as a part of the project, including male Amur trees.
“Based on the evidence provided by the Department of Agriculture, the City sees the potential for the male Amur Cork trees to become female which would make them invasive,” City of Duluth Forrester Clark Christensen said. “The City will be removing the Cork trees and replanting a noninvasive tree in its place to remediate this risk."
