The trees on school properties mirror those of the surrounding urban forest in composition but not in coverage.

That is one initial takeaway from an i-Tree Eco project on Milwaukee Public School (MPS) properties conducted by Wisconsin Department of Natural Resources (DNR) Urban Forestry interns Priscilla Loh and Taylor Colman this summer.

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.”

Are you generally hesitant to give hitchhikers a free ride?

October is National Firewood Awareness Month, and the Wisconsin Department of Natural Resources (DNR) urges state residents and visitors to follow the same line of thinking when it comes to moving firewood.

Fall Means Hunting — For Spongy Moth Egg Masses

The Wisconsin Department of Natural Resources (DNR) is encouraging property owners to seek out and dispose of spongy moth egg masses, which were produced by adult moths during the summer.

Each spongy moth egg mass contains hundreds of eggs that will hatch into hungry, leaf-eating caterpillars in the coming spring. Large numbers of these invasive caterpillars can be a tremendous nuisance that may cause tree mortality.

Time Is Right For Oak Tree Work

Do you know of a state, county, municipal or private crew that has been itching to do some work involving oak trees? Or are you a landowner itching to do some oak pruning or cutting?

Well, the time has arrived for smart and safe work on oaks.

It’s important for crews and managers to know that any damage done to oak trees from April 1 through at least mid-July — many say into September — could lead to a quick death for that tree. Frequently, one tree’s infection will also lead to eventual mortality for neighboring oaks.

Did you notice the many aspen trees in the Northwoods starting to drop their leaves in early September? These leaves were yellow with brown blotches or were brown and curled, and there were a lot of them falling.

Have you noticed black ash trees that have tightly curled leaves in scattered clumps, with lots of bare areas on the branches?

The problem might be cottony ash psyllid (Psyllopsis discrepans), a tiny, sap-sucking insect that has been in North America for almost 100 years but was first identified in Wisconsin in 2006. Its presence was reconfirmed in 2023, when it was found in several additional counties around the state. Since then, it has been identified in even more counties.

As fall settles in and hunting seasons start to open across the state, many Wisconsinites’ thoughts have turned to tree stands, blinds and all things hunting.

Planning out your perfect capture means giving yourself the best chance possible, whether slipping into or out of your tree stand or ground blind. One popular idea is camouflaging your path – using plants or trees as a natural blind so you can reach your spot without being seen by deer or other animals.
