The Wisconsin Silviculture Trials Directory was created in 2002 for foresters to document silviculture trials and share results and experiences with their peers. It is a way of documenting non-research trials in applied forestry. A trial site often visited during training sessions is the Nebish Lake oak burn. Here a forester established an oak shelterwood in 2008, followed by a prescribed burn in 2011. The results showed that fire could set back competition while creating a favorable seedbed for oak regeneration.

Forest Growth, Removal And Mortality
Forest growth, removal and mortality are indicators of forest productivity. Each forest type in Wisconsin differs in productivity based on many factors such as silvics, demand for products and overall management. Recent data from the U.S. Forest Service shows that aspen, being a short-lived species, currently has the highest mortality rate of the top ten species while eastern white pine is increasing in growth and volume.
Forestry Best Management Practices For Water Quality
Forests play an important role in maintaining, protecting and enhancing soil and water quality. With the correct application of Best Management Practices for Water Quality, foresters can protect soil and water to ensure healthy forests and habitats.
Managing For Old-Growth Forests
Old-growth forests are unique ecosystems that were historically abundant across the forested regions of Wisconsin but have now dwindled to about 1% of their original presence. Realizing the importance of old-growth forest structure and composition, the Wisconsin Department of Natural Resources (DNR) and U.S. Forest Service (USFS) partners initiated a study in 2004 to look at silviculture methods to maintain and enhance old-growth characteristics. The Managed Old Growth Silviculture Study (MOSS) continues today on public lands in northern Wisconsin including the Flambeau River State Forest, the Northern Highlands – American Legion State Forest and the Argonne Experimental Forest (located within the Chequamegon – Nicolet National Forest). The main goal of this study is to develop forest management techniques that accelerate the development of structural and compositional complexity in second-growth northern hardwoods.
Dominant Forest Types
Wisconsin’s dominant forest type group by acreage is oak/hickory (26%), followed by maple/beech/birch (22%). Oak is particularly important as it is used for quality forest products such as furniture and wildlife rely on mast (seed) production for food.
The Forestry Bubble
The middle-aged bubble does not only pertain to the baby boomer generation. Wisconsin forests are experiencing this age phenomenon as well. Wisconsin forest data shows a significant bubble of acreage in the middle age class (60-80 years old) with lesser amounts in the very young and very old age classes. This middle age bubble can be attributed in part to the cutover period when many of these forests originated.
Forests Upon Forests
Wisconsin is one of the top 25 forested states in the nation by acreage and volume. Forested land occupies about 17 million acres of Wisconsin’s nearly 37 million acres, according to data from the United States Forest Service in 2019.
Forest Characteristics, Ecology And Management In The Statewide Forest Action Plan
The success of sustainable forest management starts with a solid plan. The United States Department of Agriculture (USDA) requires each chief state forester to develop a statewide action plan every ten years. The Wisconsin plan, developed in 2020, reflects on lessons learned from the past to prepare for future challenges.
The next 12 posts are related to the “forest characteristics, ecology and management” section of the plan. Goals in this section include providing connectivity between forest patches, as well as increasing the quality and scale of forested habitat for many forest-dependent species.
Monitoring The Condition Of Wisconsin’s Forest Regeneration
Have you ever wondered how Wisconsin’s forests are monitored for regeneration? Forest regeneration, the process of renewing tree cover by establishing young trees, is one of the most basic and important elements of sustainable forest management. After a harvest or disturbance event, like a fire or heavy winds, successful regeneration is crucial to developing healthy, productive forests that can provide sustainable economic and ecological functions. Forest regrowth patterns must be well understood to manage Wisconsin’s forest resources sustainably.
In 2018, the DNR’s Forestry Division launched the Forest Regeneration Monitoring (FRM) program to better assess the status and progression of naturally regenerating forests on county, state, federal and private lands across the state.

Wood Energy – Renewable And Locally Available
Did you know that wood energy makes up a large percentage of Wisconsin’s renewable energy consumption? In 2017, biomass (including wood) accounted for an estimated 70% of the state’s renewable energy use. Are you a business, school or institution interested in learning more about whether wood energy is a good fit for you? See how the Forest Products Services program can help!
