The manufacturer, Lallemand Plant Care, recently decided to remove Rotstop® C fungicide from the North American market.

As a result, the product is no longer available for purchase in North America. If you already have the product and have stored it in an appropriate space, you may still use it as a preventative treatment for Heterobasidion root disease (HRD) as long as the expiration date has not arrived.

Campers Reminded: Don’t Move Firewood

Camping season is about to enter full swing, and campfires are a Wisconsin summer staple.

That makes this a good time for the Wisconsin Department of Natural Resources (DNR) to remind the public of the importance of protecting Wisconsin’s forests and trees by not transporting firewood long distances.

Even after a tree has died, firewood can carry pests or diseases — on its surface or inside the log —  which can attack or infect other trees. To help prevent the spread of invasive insects and diseases, always get your firewood near where you will use it.

A simple idea, to celebrate planting trees, and it’s grown into a national holiday: Arbor Day.

Arbor Day’s roots began in the late 1800s in Nebraska where, according to the Arbor Day Foundation, residents of Nebraska City felt a lack of trees in their community. The secretary of the Nebraska Territory at the time, J. Sterling Morton, proposed a statewide tree-planting holiday, and on April 10, 1872, the first Arbor Day was celebrated.

Celebrate Arbor Day Using Social Media (See Our Suggested Posts Below)

Posted on by janness

For the last few years, our urban forestry team has been writing social media posts for Wisconsin communities to post during Arbor Week. We encourage you to use social media to celebrate the many benefits of trees and inform the public about the importance of tree care.

Feel free to use the suggested messages provided below or develop your own creative tree campaign. We encourage you to use pictures of local trees in your posts to inspire community members to get out and explore the forest outside their door.

Hitchhiking invasive plants, insects and pathogens are worthy of concern.

As you dream of days spent at the cabin up north, planting your garden or wandering in the woods, here are a few reminders to help you avoid bringing hitchhiking invasives along as you enjoy your spring and summer activities.

Oak decline and mortality continue to be an issue in Wisconsin, and because of the recent droughts and spongy moth outbreak, we expect these impacts to become more widespread this summer.

Forest decline is the progressive loss of tree and stand vigor and health over several years without obvious evidence of a single causal factor. Typically, trees die in a scattered fashion across a large area over several years. The additional stress from defoliation can result in pockets of heavy oak mortality, particularly on dry, sandy sites and steep, rocky ridges and hills.

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” →
