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

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

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”

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.

Improving Employee Well-being With Exposure To Trees And Nature

By Olivia Witthun, DNR Urban Forestry Coordinator; Olivia.Witthun@wisconsin.gov or 414-750-8744

Employee attitudes and well-being improve with exposure to nature. Think about it. Every weekday we commute to work, only to be met by a dark cubicle in shades of beige and grey. Ever wonder why your mood starts to match the walls? It’s because the workplace environment contributes to employee health. We’ve known this to be true (anecdotally) for a long time, but mounting scientific evidence proves our urban and community forests have beneficial effects on employee performance.

Sampling Trees On Milwaukee Public School Campuses

By Dan Buckler, DNR Urban Forest Assessment Specialist; Daniel.Buckler@wisconsin.gov or 608-445-4578

The trees on school properties mirror those of the surrounding urban forest in composition but not in coverage.

That is one initial takeaway from an i-Tree Eco project on Milwaukee Public School (MPS) properties conducted by Wisconsin Department of Natural Resources (DNR) Urban Forestry interns Priscilla Loh and Taylor Colman this summer. Continue reading “Sampling Trees On Milwaukee Public School Campuses”

Retracted: Study Shows Drought Harms Wetter Forests Most

Note:

The original version of this Forest Health News article has been removed because the journal article in Science magazine that was referenced has been retracted by its authors due to a mathematical error. The journal authors reran their analysis and although many results remained unchanged, the statistical significance of some conclusions, and the results of some robustness tests, did change. It is unclear to what degree these errors affected observations in the Forest Health News article, so that article was removed. More information is available here.
