Cover of Forest Products JournalBy Scott Lyon, DNR Forest Products Team Leader

A new study published in the Forest Products Journal by the University of Wisconsin-Madison Extension, the United States Forest Service and the Wisconsin Department of Natural Resources examined dry kiln operations across the northeastern and north-central United States.

The research explored current technology use, production practices, and workforce training needs in the hardwood lumber drying industry, with the goal of helping training providers and industry leaders better tailor education and support to real-world operating conditions.

The survey found that most firms dry a wide range of hardwood species, reflecting the region’s diverse forest resources. Eastern white pine was the only softwood species dried by a majority of respondents. While species diversity was common across operations, the study revealed a clear divide between small and large kiln facilities in technology use, investment plans, and quality-control practices.

Based on the findings in 2025, the maps in the HRD stump treatment guidelines and online viewer have been updated. The 6-mile and 25-mile buffer zone maps in the guidelines are updated annually and good through Dec. 31, 2026.

Have you ever heard a forester talk about shelterwood or group selection and found yourself wondering what they are talking about?

Or maybe you read those terms in your forest management plan and aren’t entirely clear what they mean? If so, you might want to check out a new publication called Managing Your Woodland:
Forestry Research Translated for Landowners [PDF].

The U.S. Forest Service recently released the publication, which breaks down forest ecology, silviculture and various forest management systems for landowners and other non-forestry experts. Although the publication comes out of the Northeast United States, the tree species, forest types and forest management are not entirely different from the forests and forestry practices in Wisconsin.
