Controlling Buckthorn With Plants

buckthorn The Cover It Up project is a suite of related research projects conducted by multiple partners in Minnesota that are evaluating the ecology and management of buckthorn and other invasive plant species. Buckthorn is an invasive understory plant that was introduced to Wisconsin well over 100 years ago. It was used primarily in hedgerows, prized for its lack of pest issues and the fact it greens up early and holds its leaves well into the fall. These once desirable characteristics are also what turned this non-native into one of our state’s worst invasive species, easily outcompeting our natives, taking over Wisconsin’s forests, riparian woods, savannas, prairies, old fields, roadsides and vacant lots.

Community Spotlight: Tree Canopy Cover On Milwaukee School Properties

By Dan Buckler, DNR Urban Forest Assessment Specialist

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

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”

Wisconsin Governor Tony Evers didn’t have to go out on a limb to make this announcement.

By issuing a Governor’s Proclamation this week, Gov. Evers has shined a spotlight on Wisconsin’s 17 million acres of forestland. His announcement officially recognizes Wisconsin’s participation in Forest Appreciation Week and Arbor Day.

“Wisconsin’s trees and forests are among the state’s most beautiful and critical natural resources,” Gov. Evers wrote, “and educating kids, families and communities about sustainable forestry is vital to their long-term conservation.”

This spring, a portion of Perrot State Park in Trempealeau County will be aerially treated for spongy moth with “Foray” bacterial insecticide, containing Bacillus thuringiensis var. kurstaki.

A reproducing population of the leaf-eating caterpillar was detected in the park last fall, leading to the decision to conduct aerial spraying in 2026.

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.
