Wisconsin Silviculture Trials

Posted on by grace.hershberg

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.

Managing For Old-Growth Forests

Posted on by grace.hershberg

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.

How do Wisconsin professionals use outreach materials to engage residents in urban tree care?

Posted on by margueriterapp

The Wisconsin Department of Natural Resources (DNR) and UW-Madison Division of Extension (UWEX) are partnering to better understand the informational resources available to professionals who provide tree care advice and services to urban residents in Wisconsin. Using information collected from an exploratory survey in early 2019, DNR and UWEX staff plan to improve access to these resources and address additional needs by creating new resources. Next steps include identifying a place where existing and new materials can be easily accessed by all audiences.

When asked to report the most commonly discussed topics with homeowners, pests and diseases emerged as the top issue (36% of respondents) with tree planting/care/selection or tree pruning as other popular topics (20-23% of respondents respectively). While 75% of respondents say that they use verbal advice to share information with residents always or most of the time, they also identified a diverse range of topics and types of content that they would find useful when communicating with their audiences.

Wisconsin DNR Urban Forestry News subscriber survey

Posted on by margueriterapp

Introduction

Providing timely and relevant information to the Wisconsin urban forestry community is a key role of the Wisconsin DNR Urban Forestry program. One of the ways in which this goal manifests itself is through a monthly newsletter received by 5,555 subscribers (May 2019). In order to ensure that the newsletter content is relevant and timely, the Urban Forestry program surveyed subscribers in spring 2019. Results are shown and interpreted below and suggestions made for future newsletter editions. Continue reading “Wisconsin DNR Urban Forestry News subscriber survey” →

Inaugural ‘Good Health Grows on Trees’ conference a success!

Posted on by margueriterapp

Whether it be a hike through the woods, time spent with your family at a local park or sitting beneath the shade of that stately red oak in your backyard, we, as urban forestry professionals and enthusiasts, experience and recognize the physical, mental and spiritual benefits of spending time outdoors in nature.

For decades, scientists have been researching and documenting the health benefits that trees and nature provide, and as urban populations continue to rise, the impact of nearby nature on human health has generated a lot of interest in our world of urban and community forestry.

To further that conversation in Wisconsin, the first ever ‘Good Health Grows on Trees: The Influence of Nearby Nature on Public Health’ conference was hosted by the DNR Urban Forestry program at the Rotary Botanical Gardens in Janesville on May 30th.  Continue reading “Inaugural ‘Good Health Grows on Trees’ conference a success!” →

One step closer to market: Renewable energy flooring makes debut in Union South
By Will Cushman, UW-Madison, Environmental Resources Center

As tens of thousands of visitors each day walk across a new flooring installation in UW-Madison’s Union South in fall 2017, they might not realize they’re participating in what could very well represent a leap into the future of renewable energy production.

A research team led by Xudong Wang, a University of Wisconsin-Madison professor of materials science and engineering, in collaboration with the UW-Madison Grainger Institute for Engineering, has installed a high-tech flooring prototype that harvests the energy of footsteps and converts it into electricity.

Are gravel beds right for your community?

Posted on by Ellen Clark

Gravel beds, a way of holding bare root trees and extending the bare root planting season, have been growing in popularity, especially in the Midwest. Several municipalities and other organizations throughout Wisconsin have been utilizing gravel beds to plant more trees on tight budgets, diversify plantings, decrease labor and ensure sound, healthy root systems. Hudson and Racine are wonderful examples of the success of gravel beds. Continue reading “Are gravel beds right for your community?” →
