Just a few weeks ago a news story was released regarding the discovery of several new emerald ash borer (EAB) infestations in Minnesota. One case was confirmed in Minneapolis, and two in St. Paul. In late January, the Minnesota Department of Agriculture performed a follow-up on reports submitted by the Minneapolis Parks and Recreation Board Forestry Department and the St. Paul Forestry Unit regarding possible emerald ash borer infested trees. They were able to confirm that the trees were infested after removing bark from the suspected trees and finding the distinctive “S” shaped tunnels, which are created by the larvae of the EAB.
Interestingly, the suspected infested ash trees were discovered because it had been observed that there was a higher amount of woodpecker activity and feeding happening on and around those particular trees. Increase of woodpecker traffic on a particular ash tree is a good indicator of insect activity in an infected tree. The greater amount of damage inflicted to the tree by the woodpeckers (debarking areas of the tree, many parts of the tree showing woodpecker activity) can indicate just how severely a tree has been infected. While it may appear that the woodpeckers are the problem because they’re causing visible damage to the tree, they are merely looking for food, and it’s the food they crave that’s killing the tree.
Winter is the best time of year to find, observe and confirm infested trees because the tree lacks leaves which can hide infestation symptoms. The trunk and all the branches can easily be visually inspected for EAB indicators, such as woodpecker damage and discoloration of bark.
