Leaf drop is the best time to check ash trees around the Brainerd Lakes area for emerald ash borer damage.
Emerald ash borer has been spreading across Minnesota, and ash trees in the region are at risk. Signs include thinning in the upper canopy, patches of bark flaked off by woodpeckers (often called blonding), vertical splits in the bark, and small D-shaped exit holes. Most infested trees decline quickly once symptoms are visible.
With the leaves gone, woodpecker damage and bark splits are much easier to see from the ground. An infested ash becomes brittle as it dies, which makes removal more dangerous the longer it waits, especially near homes, cabins, and power lines. Wood from infested ash should stay local to avoid spreading the insect.
An honest assessment is the first step, whether that means keeping an eye on a healthy tree or planning a safe removal on your timeline, from Baxter to Pequot Lakes.
