This spring, the Wisconsin Department of Natural Resources (DNR) is collaborating with the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) to set traps to detect the invasive insect hemlock woolly adelgid (Adelges tsugae; HWA).

The project, funded by the Wisconsin Specialty Crop Block Grant Program, calls for traps to be set to detect the invasive insect. No detection of HWA has been made to date in Wisconsin forests. Continue reading “Cooperative Hemlock Woolly Adelgid Trapping Effort Begins” →

Note: This is the first installment in the Forest Health News “Invasives Spotlight” series, a monthly series of Forest Health News articles.

Many people recognize honeysuckle as a fast-spreading invasive shrub that can quickly displace native vegetation. But did you know that some honeysuckles exist as a vine?

Japanese honeysuckle (Lonicera japonica) is an invasive perennial vine that can grow to a length of 80 feet or longer. Birds will often eat and disperse the berries the vine produces, allowing for the creation of new populations.

Adult blacklegged (deer) ticks are already active this year, as of March 2026. The adults start looking for a host as soon as it warms up to around 40 degrees Fahrenheit.

In Wisconsin, between 20-60 percent of adult ticks are infected with the bacteria that causes Lyme disease. However, the risk of getting Lyme disease is higher with bites from nymphal ticks, which are most abundant in June and July, because they are so tiny and difficult to find. While only 10-28 percent of nymphs are infected with the Lyme disease bacteria in Wisconsin, rapid removal of a tick can reduce the risk of infection because it takes at least 24 hours for the Lyme bacteria to spread.

With camping season about to enter full swing, the Wisconsin Department of Natural Resources (DNR) urges campers to think twice before giving invasive species or harmful hitchhikers a ride in their firewood.

Memorial Day marks the unofficial start of summer, and campfires are a Wisconsin summer staple. And campers should know it’s a big help to the state’s trees when they help to prevent the spread of invasive pests by making smart firewood choices.

Community Spotlight: Tree Canopy Cover On Milwaukee School Properties

The thought of increasing a community’s tree canopy cover is sometimes overwhelming given how many landowners are present. Think about all the stakeholders who have to buy into the initiative, not only with enthusiasm, but likely contributing money and time as well.

Contrast that with a more actionable approach focused on areas where there’s a single landowner or manager.

This was the route taken by graduate student Michelle Hess in a recent paper for a UW-Milwaukee Geography course. Michelle investigated tree canopy on Milwaukee Public Schools (MPS) properties to identify which schools should be prioritized for future greening initiatives, like those organized through ReFlo. The goal was to use canopy data provided by the DNR, identify which schools had lower canopy cover, merge those data with median household income of the local Census tract and come up with a prioritized list of schools in need of tree planting.

Keep Wildlife Wild: Know What To Do If You Encounter Young Wild Animals This Spring

Posted on by janness

fawn behind leavesAs warmer weather approaches, the Wisconsin Department of Natural Resources (DNR) reminds the public that wild animals and their young will be on the move across Wisconsin.

“Springtime brings a flurry of inquiries from concerned individuals about the wildlife they are encountering. It is perfectly natural for many species of young wild animals to be left alone for extended periods of time, and they should not be disturbed,” said Jenna Fastner, DNR captive wildlife health specialist. “Wild animals are well-adapted to life in the wild and learning natural behaviors from their own species is imperative to their survival.”

Knowing what to do before you find a young wild animal can make all the difference in the moment to protect it and keep it in the wild with its parents. Continue reading “Keep Wildlife Wild: Know What To Do If You Encounter Young Wild Animals This Spring” →

It takes more than one celebration to pay tribute to Wisconsin’s 17 million acres of rich, diverse forestland.

So, the state has come up with multiple ways to acknowledge the value of trees to Wisconsin’s ecology, economy, health and way of life. Three of the biggest ones are taking place in April:

  • Earth Day will be observed on Wednesday, April 22.
  • Arbor Day is set for Friday, April 24.
  • Forest Appreciation Week runs April 20-24 statewide, covering both of those dates.
