A simple idea, to celebrate planting trees, and it’s grown into a national holiday: Arbor Day.

Arbor Day’s roots began in the late 1800s in Nebraska where, according to the Arbor Day Foundation, residents of Nebraska City felt a lack of trees in their community. The secretary of the Nebraska Territory at the time, J. Sterling Morton, proposed a statewide tree-planting holiday, and on April 10, 1872, the first Arbor Day was celebrated.

Resources to Help Urban Foresters Set And Meet Tree Diversity Goals

Urban foresters are increasingly aware of the importance of tree species, age and size diversity to ensure resilient tree canopy and all the associated benefits in their communities. The 20-10-5 rule, which specifies that no more than 20% of trees planted should be from one family, no more than 10% from one genus and no more than 5% from one species (including cultivars), can be helpful in setting tree diversity goals. Applying these guidelines can provide urban forests some protection against huge losses caused by invasive forest pests.

Celebrate Arbor Day Using Social Media (See Our Suggested Posts Below)

Posted on by janness

For the last few years, our urban forestry team has been writing social media posts for Wisconsin communities to post during Arbor Week. We encourage you to use social media to celebrate the many benefits of trees and inform the public about the importance of tree care.

Feel free to use the suggested messages provided below or develop your own creative tree campaign. We encourage you to use pictures of local trees in your posts to inspire community members to get out and explore the forest outside their door.

The Wisconsin Urban Forestry Council presents annual awards for furthering urban forestry in the state.

The Wisconsin Urban Forestry Council recently announced its annual awards honoring those dedicated to protecting, preserving and increasing the number of trees that line city streets, fill community parks and beautify neighborhoods throughout the state.

The Wisconsin Urban Forestry Council advises the Wisconsin Department of Natural Resources (DNR) on managing urban and community forest resources.

“Each year, these awards remind me of how special the people are in our industry and the numerous accomplishments they fulfill,” said Lee Fredericks, Wisconsin Urban Forestry Council Award Committee Chair. “Whether they are taking on projects to expand their leadership, involving the next generation of arborists or advancing species diversity in the urban forest canopy, the state as a whole truly benefits.”

This year’s recipients were announced at the 2025 Wisconsin Arborist Association/DNR Urban Forestry Conference in Green Bay. The categories and winners are: Continue reading “Wisconsin Tree Leaders Recognized For Exceptional Community Service” →

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.

Right Tree, Right Place

Earth Day, Arbor Day and spring are all quickly approaching, and now is the time to start thinking about your tree plantings! Choosing the proper tree for a specific location will help ensure your tree’s long-term health and survival.

Think: “Right tree, right place.” It’s an old phrase, but the message is powerful and remains true today.

When selecting the right tree for your spot, many factors must be considered. Check out Choosing the Right Landscape Plants: Factors to Consider for a list of important considerations, such as landscape function, size and form, ornamental factors and pest issues. It even includes information on how to select high-quality trees in the nursery. Continue reading “Right Tree, Right Place” →

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” →
