Hardwood lumber production in the United States reached a peak in 1999, with an estimated 12.6 billion board feet of output. However, the early 2000s ushered in a major structural shift – the large-scale offshoring of U.S. furniture manufacturing. Once the single largest user of hardwood lumber until the late 1970s, wood furniture has become the smallest major market for hardwood lumber today.

The Blanchette Forest Pathology Lab at the University of Minnesota is leading a project to study black locust in Minnesota and Wisconsin and requests the help of foresters and the public in locating stands of dying black locust (Robinio pseudoacacia) this summer.

The university plans to collect native pathogenic fungi from stands of dying black locust and testing them for their suitability to biologically control black locust clones.

Cemetery Trees Of Southeast Wisconsin Study Now Available

Cemeteries are important and, to many people, sacred spaces in our communities. The landscaping of these places serves the dead, of course, but can also have a profound impact on the experiences of cemetery visitors and nearby residents. This is accomplished by vegetation and art, which encourages expressions of grief and melancholy but also celebration and hope.

Trees are a prominent part of this landscaping and this mission.

DNR Urban Forestry staff in the Milwaukee office became interested in these spaces and exploring whether we could offer ways to assist cemetery managers. Continue reading “Cemetery Trees Of Southeast Wisconsin Study Now Available” →

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.

Annual program reports can be a very useful tool. One example is Cedarburg’s 2025 urban forestry report. It is detailed, yet not overwhelming, and the format provides for easy comprehension at a quick glance. The annual report includes things like: a mission statement, the number and location of vacant plantable sites, removal/planting/pruning numbers, specific cultivars planted, types and reasons for pruning and a comparison to previous years.

The report is shared with Cedarburg’s Parks & Forestry Board, City Council, and other leadership and can also be found on their website. Cedarburg’s city forester attends these local meetings, goes over the main points in the report and answers any questions they may have. Additionally, some of the information is useful when filling out their Tree City USA application. Continue reading “Community Spotlight: Cedarburg’s UF Program – 2025 Report” →

Wisconsin experienced a polar vortex in late January 2026, and temperatures got chilly throughout the state, even reaching close to -40⁰ F in some places! Although it has warmed up, the cold weather is still fresh in everyone’s minds, leaving insect and forest lovers alike wondering how insects survive temperatures that cold.

The Wisconsin Department of Natural Resources Forest Health staff has received several questions over the past month about how insects survive cold weather in winter and whether the January temperatures were cold enough to kill insect pests.
