It takes more than a village to foster healthy forests. More than a township, a city and a county, too. Sometimes, even more than a state.

That’s why the Great Lakes Basin Forest Health Cooperative (GLB FHC) was formed four years ago by Holden Arboretum in Ohio and the U.S. Department of Agriculture Forest Service.

Geographically, the group’s region encompasses an area from New Jersey to Wisconsin. The Wisconsin Department of Natural Resources (DNR) is an active member.

This summer’s detection of emerald ash borer (EAB) in Burnett County means our little metallic friend (or should I say foe?) is now known to be present in all 72 Wisconsin counties.

While EAB has been around for the better part of two decades in Wisconsin, many homeowners are still in the thick of dealing with the fallout of this invasive pest.

Hemlock woolly adelgid (HWA) and balsam woolly adelgid (BWA) are invasive, aphid-like insects that cause tree mortality in North America. Neither has been found in Wisconsin so far, but they are likely to arrive at some point, as they have been confirmed in Michigan.

HWA (Adelges tsugae) is an invasive, sucking insect pest of hemlock trees. The white, cottony egg sacs of HWA can be seen on the undersides of hemlock branches at the base of needles year-round. HWA saliva enters the tree while feeding. The saliva is toxic and causes needle drop and twig dieback, progressing to tree mortality in 4-10 years.

Heterobasidion root disease (HRD), formerly known as annosum root rot, was recently found in Door County for the first time.

In mid-September, several suspected HRD fruiting bodies were spotted in a white spruce plantation on privately owned land in the town of Sevastopol. One cluster of fruiting bodies located at the base of a dead spruce was confirmed as Heterobasidion irregulare, the fungal pathogen that causes HRD. The other fruiting bodies were identified as a native decay fungus that has a similar appearance.

Once again, it’s time for nature’s majestic paintbrush to spread its magic across Wisconsin.

Many of the state’s trees have begun to show off their amazing fall colors, brightening the view for state residents and visitors everywhere – from the restful resplendence of our urban areas and state properties to the drive-by dazzlement of our tree-lined country roads.

“It’s a brilliant and colorful display,” said Scott Lyon, leader of the Wisconsin Department of Natural Resources Forest Products team. “The Badger State is home to many deciduous hardwood species which change colors and lose their leaves as the seasons change, including maple, oaks, hickories and aspen.”
