The price of wood is soaring. To save a little money, the technology education department at McFarland High School has devised an ingenuous DIY cost-saving scheme.

Since 2019, Steve Pennekamp’s woodworking classes have been milling their own lumber. The village, in a partnership with the students, provides the logs, removed from projects around town. Continue reading “Lumber Milling At McFarland High School” →

Winter Tree ID

Posted on by janness

How do you learn to identify trees in the middle of a Wisconsin winter when most of the leaves are on the ground?

LEAF’s Winter Tree Key follows the dichotomous process of our regular tree key but uses detailed illustrations of buds, twigs and features other than leaves for identification. The key also includes an illustrated glossary defining the specific vocabulary involved in this process. Winter tree identification can be a bit more demanding. Continue reading “Winter Tree ID” →

Part Two of a report on spongy moth in Wisconsin in 2024 and 2025. Part One was published in December.

The Wisconsin Department of Natural Resources (DNR) is encouraging property owners to examine their property for spongy moth egg masses and plan for action this spring if needed. Each spongy moth egg mass contains hundreds of eggs that will hatch into hungry, leaf-eating caterpillars this spring. Large numbers of these invasive caterpillars can be a tremendous nuisance that may cause tree mortality.

Winter is an ideal time to perform trimming, cutting and brush removal work on and near oak trees.

For one thing, it’s a low-risk period for the trees to be infected with oak wilt, a fungal disease spread by beetles. When a red oak is infected with oak wilt, it will die that year; the disease also stresses trees in the white oak group, often fatal with bur oaks and swamp white oaks.

Woodpecker Flecking On Ash Means EAB

Ash trees that are flecked by woodpeckers will have the outer layers of their bark chipped off by the birds. Woodpeckers do this to punch through the remaining bark more easily to get at the tasty emerald ash borer (EAB) larvae living there.

Flecking usually starts at the top of the tree, providing a sure sign that insects are under the bark. Although the problem could be caused by ash bark beetles, the more common culprit is EAB.

Impacts Of Winter Weather On Trees

Winter damage can significantly impact the health of trees. Keeping trees healthy through the fall is important for reducing winter stress. In dry falls, like the one Wisconsin experienced in 2024, you can help trees go into winter healthy by continuing to provide water to them until the leaves start falling (for deciduous trees) or until the ground starts freezing (for conifers).
