Tree removal at Dwan focuses on urban forest health

When Emerald Ash Borer (EAB) was discovered in Bloomington in 2014, City staff surveyed the ash trees at Dwan to identify trees with signs of infestation. To strengthen resistance, ash trees that were obstructing the course or storm damaged were removed. Dwan had 207 ash trees on the course at the time. By 2021, approximately 100 ash trees
were removed.

Even with those proactive efforts, the first signs of EAB were discovered at Dwan in 2022. City forestry crews surveyed and tagged the trees and Dwan management developed a plan identifying which trees were healthy enough to treat and which should be removed.

Removing infested or unhealthy trees susceptible to infestation is vital in maintaining a healthy urban forest, and so is replacing trees. In 2015, the City launched an Ash Tree Replacement Plan and has planted more than 40 trees on the Dwan course.
