The Wisconsin Department of Natural Resources (DNR) Forest Products Services recently worked with UW-Extension and the Department of Agriculture Forest Products Lab to develop a technical primer highlighting vacuum drying technologies for lumber manufacturing.
This research was completed by using the vacuum kiln at Northcentral Technical College. Vacuum drying technology has recently gained attention in Wisconsin because of the availability of lower-cost vacuum kilns for smaller wood product manufacturers.
Vacuum drying utilizes a pressure vessel, a heat source and a vacuum pump to control the drying conditions under less-than-atmospheric pressure. This process is an economical alternative to conventional drying for many species under various environmental and economic conditions.
Vacuum drying can reduce drying time and be more energy-efficient than conventional steam drying. However, there are many factors to consider when comparing the two technologies. Ideal applications for vacuum kilns include high-value wood species, difficult-to-dry species (e.g. oak), timbers, large sections of logs and lumber (including live-edge slabs and wooden rounds), decorative or thick veneer and small-scale woodworking operations.
The new report describes the principles and practices of vacuum drying and discusses its advantages and disadvantages. To learn more about this technology and drying lumber, please view the recent technical report by visiting this webpage.
A group of researchers and Extension professionals from Michigan, Minnesota, and Wisconsin are working on a “Woodsheds” mapping project (similar to the concept of a watershed) to develop an interactive web-based mapping application they hope will be useful for forest landowners, forestry professionals, and wood products industry professionals. A 5-10 minute survey is intended to find out what your information needs are, and to see if you’d like to be part of a user testing group that helps them refine this tool. Direct any survey questions to email@example.com. Please use this link to complete the survey by April 18th:

Conservation partners, including Ducks Unlimited, Wisconsin DNR, U.S. Fish and Wildlife Service, City of Green Bay and UW-Green Bay, worked together to construct a woody breakwater to restore and enhance wetlands for wildlife and more.
The project took place in fall 2021 at the mouth of Duck Creek, offshore from the Ken Euers Nature Area in Green Bay, Wisconsin. The project involved several years of planning that brought together a team of fish and wildlife biologists, wetland and aquatic plant scientists, foresters and engineers to discuss ideas and plans to restore wetland vegetation in the Duck Creek Delta.
Steve Kaufman, DNR Forester on the Oconto Falls team, and Scott Lyon, DNR Forest Products Specialist with Forest Products Services, participated in technical advisory committee meetings and assisted in connecting the project coordinators with woody materials to be used in the structure.
The resulting breakwater structures were predominantly trees rather than a traditional breakwall composed of mostly rock and is one of the first for the bay of Green Bay and the broader Great Lakes system. Continue reading “Restoring Coastal Wetlands With Low-Value Woody Material”

Acres Of Black Walnut Forests
Black walnut is a valuable and highly sought-after species found in the Midwest and Eastern United States. In Wisconsin, its distribution is primarily limited to the state’s southern region, although scattered sites are found farther north. The total acreage of black walnut in the state has increased nearly three times, from approximately 35,065 acres in 2004, to 101,274 acres in 2019.
Of that total, surprisingly, only 10% is attributed to stands established by artificial regeneration. The distribution of acres by stand age shows a boon in stands aged 31 to 90 years since 2004, with younger age classes remaining relatively steady since 2009 (Figure 1). Relatively few stands have reached ages over 90 years.

Chapter 1 of the Private Forestry Handbook is available for stakeholder review and comment through April 4, 2022.
This chapter covers program guidelines for DNR forestry staff regarding their work with private woodland owners, including establishing walk-through service standards and a property walk-through policy. We’re updating this chapter to establish a property walk-through policy since there was no set standard for this important interaction with private woodland owners.
To review and provide feedback on this document, please visit the DNR Forestry Stakeholder Input Page.

The Wisconsin Department of Natural Resources (DNR) Division of Forestry’s reforestation program will accept seedling orders from Wisconsin forest landowners for trees and shrubs to be planted in spring 2022 starting Oct. 4, 2021. The high-quality seedlings are native species appropriate for planting throughout Wisconsin.
Seedlings grown by the state nurseries are used for reforestation and conservation plantings on private, public and tribal lands. These seedlings can provide future forest products and revenues, wildlife habitat, soil erosion control, living snow fences, aesthetics and shade to landowners and managers in every state county.
