“Acts of creation are ordinarily reserved for gods and poets. To plant a pine, one need only own a shovel.”

Those were the words of Wisconsin’s most prominent conservation expert, Aldo Leopold, who authored the famous book, “A Sand County Almanac” among his many achievements.

This month, everyone in Wisconsin will have the chance to follow Leopold’s advice – even if in a small way, because many small efforts can add up to a prominent positive impact on Wisconsin’s trees and forests.

The Wisconsin Urban Forestry Council presents annual awards for furthering urban forestry in the state.

The Wisconsin Urban Forestry Council recently announced its annual awards honoring those dedicated to protecting, preserving and increasing the number of trees that line city streets, fill community parks and beautify neighborhoods throughout the state.

The Wisconsin Urban Forestry Council advises the Wisconsin Department of Natural Resources (DNR) on managing urban and community forest resources.

“Each year, these awards remind me of how special the people are in our industry and the numerous accomplishments they fulfill,” said Lee Fredericks, Wisconsin Urban Forestry Council Award Committee Chair. “Whether they are taking on projects to expand their leadership, involving the next generation of arborists or advancing species diversity in the urban forest canopy, the state as a whole truly benefits.”

This year’s recipients were announced at the 2025 Wisconsin Arborist Association/DNR Urban Forestry Conference in Green Bay. The categories and winners are: Continue reading “Wisconsin Tree Leaders Recognized For Exceptional Community Service” →

With warmer spring weather fast approaching, the Wisconsin Department of Natural Resources (DNR) recommends protecting oaks from the often-fatal disease, oak wilt, by refraining from pruning, cutting or injuring oak trees from April through July.

Oak wilt is a serious disease that kills trees in the red oak group (including pin oak, northern red oak and black oak) and weakens those in the white oak group (bur oak, swamp white oak, white oak and English oak).

Property owners with healthy, valuable ash trees are encouraged to treat them with insecticide this spring to protect against emerald ash borer (EAB).

The invasive pest is currently the most damaging threat to trees in Wisconsin, killing more than 99% of the ash trees it infests.

Paul Cigan, the Wisconsin Department of Natural Resources’ (DNR) forest health specialist for the northwest zone, recently appeared on the Ventures of the Land podcast, hosted by George Atwell, to discuss oak wilt’s past, present and future in Wisconsin.

The talk included details on how and when the invasive fungal disease arrived in the state, how it attacks oak trees and methods landowners can use to manage the disease.

The April 1 application deadline for Weed Management Area-Private Forest Grant Program (WMA-PFGP) grants is coming up. There is still time to apply for funding to help you control invasive plants on your forested land in 2025.

Controlling invasive plants on your forested property can be a challenging and costly endeavor. WMA-PFGP grants help to make this process a little easier for its recipients.

It might be a bit chilly these days, but spring is coming. When the weather warms up, the annual return of spongy moth caterpillars will begin.

There’s a way for landowners to make a dent in the population of the hungry caterpillars: Get out now to locate and properly dispose of spongy moth egg masses, produced by adult moths last summer.

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.
