We are pleased to offer a new resource to communities to help assess, celebrate and share information about your community’s trees and the benefits they provide.

For the 165 communities that we have inventory data on (those communities within the Wisconsin Community Tree Map), we have created summary sheets like the sample shown below. These offer a quick snapshot of your community’s species and structural diversity, canopy cover and the i-Tree derived ecosystem services for both the publicly maintained trees as well as those of the whole community.

Cemetery Trees Of Southeast Wisconsin Study Now Available

Cemeteries are important and, to many people, sacred spaces in our communities. The landscaping of these places serves the dead, of course, but can also have a profound impact on the experiences of cemetery visitors and nearby residents. This is accomplished by vegetation and art, which encourages expressions of grief and melancholy but also celebration and hope.

Trees are a prominent part of this landscaping and this mission.

DNR Urban Forestry staff in the Milwaukee office became interested in these spaces and exploring whether we could offer ways to assist cemetery managers. Continue reading “Cemetery Trees Of Southeast Wisconsin Study Now Available” →

Annual program reports can be a very useful tool. One example is Cedarburg’s 2025 urban forestry report. It is detailed, yet not overwhelming, and the format provides for easy comprehension at a quick glance. The annual report includes things like: a mission statement, the number and location of vacant plantable sites, removal/planting/pruning numbers, specific cultivars planted, types and reasons for pruning and a comparison to previous years.

The report is shared with Cedarburg’s Parks & Forestry Board, City Council, and other leadership and can also be found on their website. Cedarburg’s city forester attends these local meetings, goes over the main points in the report and answers any questions they may have. Additionally, some of the information is useful when filling out their Tree City USA application. Continue reading “Community Spotlight: Cedarburg’s UF Program – 2025 Report” →

A New, Intuitive Way To Measure Species Diversity

Especially in the wake of emerald ash borer, urban foresters have stressed species diversity as an important goal in the management of local trees. Now there is a new, intuitive way of tracking species diversity by simply counting how many species it takes to make up half of your community’s trees.

This metric is called the top diversity index, or TD-50 index, and was proposed in a 2022 article in Urban Forestry and Urban Greening by Natalie Love and others. The index is deceptively simple — by counting the minimum number of species it takes to comprise 50% of your trees, you have an easy benchmark to improve upon to reduce your reliance on a few species.

Community Spotlight: West Allis’ Tree Inventory System

Posted on by janness

It was 2021 and the West Allis Forestry Division faced a crisis. For all intents and purposes, its tree inventory was no longer functional. The division had always been a program that kept and used a lot of data, but inefficiencies in the inventory process abounded, and now the software where the data was stored was essentially crashing. The status quo was clearly not working.

But as Winston Churchill apocryphally said, “Don’t let a crisis go to waste.”

Do you have a tree inventory but have a hard time keeping it up to date? Or are you interested in inventorying trees from scratch?

The Department of Natural Resources (DNR) has made a handful of “subaccounts” available for communities or organizations to edit data within the Wisconsin Community Tree Map at no cost to the community or organization.

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.

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.
