As part of the Wisconsin Department of Natural Resources Forest Products Services mandate to explore new markets for species considered underutilized in the state, a research project was proposed to evaluate the viability of Eastern white pine (EWP) in cross-laminated timber (CLT) panels.

CLT has become increasingly popular in the U.S. during the last decade-plus, after the product was determined to be an effective alternative to traditional concrete and steel construction for multi-story construction in Europe. It is created by pressing dimension lumber (2x4s and 2x6s, typically) into large panels where each layer runs perpendicular to those above or below it, similar to plywood. This construction method allows for large structural panels to be created entirely from wood.

Urban Forest Inventory And Analysis Release

Much of what we know about our urban forests is limited to publicly maintained spaces such as in parks or along streets. However, the curtain covering other urban lands is rising, starting in Milwaukee and Madison.

The Urban Forest Inventory and Analysis (UFIA) program, a partnership between the USDA Forest Service and the DNR, has established 1,300 permanent plots in urban areas across Wisconsin. Project foresters captured loads of information on each plot, such as tree species and sizes, land ownership, tree damages, and wood volume. The data were extrapolated from those plots and made into estimates for each city. The data were also incorporated into i-Tree to calculate ecosystem services.

A Hopefully Not-Too-Deep Look Into i-Tree Benefits

Trees work in mysterious ways, and, for some users, so does i-Tree. The suite of software, developed by the USDA Forest Service and Davey Tree Expert Company, can, among other things, calculate the societal benefits of trees. Below, I try to summarize and demystify some of these estimates of ecosystem services, a somewhat sterile term for some of the cool things trees do for society and the wider environment.

Because the benefits identified in i-Tree only scratch the surface of trees’ importance to one’s community, it could be problematic and limiting if estimates from i-Tree are solely relied on to justify the investment in tree preservation, maintenance or planting. Nonetheless, these estimates help tell the story of the good work trees do in our communities. Continue reading “A Hopefully Not-Too-Deep Look Into i-Tree Benefits” →

Cambridge Tree Trials

Posted on by janness

By Jay Weiss, Cambridge Tree Project Executive Director

When the Cambridge Tree Project launched nearly 20 years ago, urban tree growth and survival data were nearly impossible to find. In response, I began tracking the trees my nonprofit donated to the Village of Cambridge to assess their performance.

To date, I have records for 1,375 trees planted throughout Cambridge and have taken nearly 9,000 annual tree growth measurements. This dataset, known as the Cambridge Tree Trials, is openly shared for educational purposes in the form of annual updates emailed to over 450 forestry professionals across America. To be added to the distribution list, email jay@cambridgetreeproject.org. Continue reading “Cambridge Tree Trials” →

Urban Forestry Internship Application Period Now Open

Posted on by janness

The application period is now open for hundreds of internships with the state of Wisconsin, including two positions with the DNR’s Urban Forestry program!

The urban forest interns will focus on data collection and analysis projects to expand our knowledge of the sustainable management of community forests. Daily work will mostly consist of different tree inventory projects, with opportunities to learn about the wider forestry and urban forestry fields in Wisconsin. Continue reading “Urban Forestry Internship Application Period Now Open” →

New Tree Canopy Resources Released

Urban Tree Canopy (UTC) assessments using aerial or satellite imagery have been one of the primary ways people estimate the extent of urban forests across an area of interest, whether it be a single park, a streetscape or a whole community.

Two recently released UTC resources are ready for use by Wisconsin communities and urban forestry practitioners. The first, TreeCanopy.us, is a mapping application that shows UTC and other land cover in urban areas across the country for 2017 and 2022. It also shows changes in canopy cover between those five years. Continue reading “New Tree Canopy Resources Released” →

Please Submit Trees Planted This Year!

Autumn is a wonderful time for planting trees. And after the trees go in the ground, please take a few minutes to document the effort in the Wisconsin Tree Planting Map. The map was designed to help track trees planted to advance the state’s pledge to the Trillion Trees Initiative.

Tree City USA: Wisconsin Can Take The Lead In Growth Awards Earned With Your Help

Posted on by janness

By Abby Krause, DNR Urban Forestry Coordinator; Abigail.Krause@wisconsin.gov or 608-556-5690

Tree City USA is an annual recognition program presented by the Arbor Day Foundation that allows communities to publicly demonstrate their continued commitment to the care of their local urban forest. Returning Tree City USA communities are also eligible to apply for Growth Awards. These awards recognize community forestry programs that go above and beyond the four core tenets of Tree City USA.

Wisconsin has consistently proven to be a national leader in the stewardship of the forests outside our front doors all across the state. In 2023, we saw participation from Milwaukee, our state’s most populous city, down to Ephraim, a village of only a few hundred residents. We ranked third nationally in both programs with 194 Tree City USA communities and 26 Growth Awards. Only Ohio and Illinois ranked higher.

It takes more than a village to foster healthy forests. More than a township, a city and a county, too. Sometimes, even more than a state.

That’s why the Great Lakes Basin Forest Health Cooperative (GLB FHC) was formed four years ago by Holden Arboretum in Ohio and the U.S. Department of Agriculture Forest Service.

Geographically, the group’s region encompasses an area from New Jersey to Wisconsin. The Wisconsin Department of Natural Resources (DNR) is an active member.

Sustainable Forestry Initiative Urban Forest Improvement Grant Application Now Open

Posted on by janness

The Urban Forest Improvement Program, funded by the Inflation Reduction Act and the USDA Forest Service’s Urban and Community Forestry Program, provides grants to help organizations benchmark their urban or community forests against the Sustainable Forestry Initiative (SFI) Urban and Community Forest Sustainability Standard.

These grants support the assessment of current management practices, offering valuable insights into how sustainably these forests are managed and a roadmap of opportunities for improvement. Continue reading “Sustainable Forestry Initiative Urban Forest Improvement Grant Application Now Open” →
