As of July 1, 2026, cities, villages, towns, counties, tribes and 501(c)(3) nonprofit organizations in – or conducting their projects in – Wisconsin can apply for a regular or startup 2027 Wisconsin Department of Natural Resources (DNR) Urban Forestry grant.

Regular Urban Forestry grants range from $1,000 to $25,000 and grant recipients must match each grant dollar for dollar. These grants fund projects that improve a community’s capacity to manage its trees (e.g., management plans, ordinances, staff training, tree board development, inventories and public education) and projects that help conserve, protect, expand or improve the urban forest resource (e.g., planting, hazard tree removal, pest control).

Community Spotlight: Manitowoc’s Multifaceted Replanting Strategy

As a long-time Tree City USA (43 years) and frequent Growth Award recipient (14 years in a row!), Manitowoc has a deep-rooted tradition of supporting urban forestry. After the emerald ash borer was detected in Manitowoc County in 2016, the city redoubled its efforts. Hundreds of dead and declining ash trees have been removed, and thousands of diverse, pest- and disease-resistant trees have been planted to replace the lost canopy.

Manitowoc utilizes a variety of programs, methods and funding sources to plant trees. Read on to learn more about their creative, multifaceted replanting strategy. Continue reading “Community Spotlight: Manitowoc’s Multifaceted Replanting Strategy” →

Students Graduate From The Community Tree Management Institute

a group of people examining tree leavesCongratulations to the latest class of Wisconsin Community Tree Management Institute (CTMI) graduates! The CTMI wrapped up its sixth cohort mid-June.

CTMI is an advanced training course designed specifically for people responsible for urban forest management who do not have a degree and/or experience in urban forestry. Conversely, they may have technical skills but lack leadership and management experience.

Over six days of intensive training, students acquired the knowledge and skills needed to manage municipal trees and green space. Their exposure to various teaching perspectives gave them a well-rounded 38-hour training experience. The retreat-like setting created by the small class size and interactive learning curriculum reinforced the focus on support-network development with other students, staff and instructors. The capstone of the institute required each student to complete an applied project that benefited their community by utilizing their new skills and knowledge.

How Big Will My Tree Get?

This is one of my least favorite questions to get as an urban forester/arborist; it’s right up there with “how old is my tree?” The reason I despise this question is not because it is a bad question, but rather it is a complex one. A question that often requires much more discussion than the person who asked it is looking for… Continue reading “How Big Will My Tree Get?” →

Tree Species In An Uncertain Future Climate

One of the many challenges for urban foresters in navigating climate change is the fact that while temperatures are elevated across every season, it can still get pretty cold in Wisconsin, even along Lake Michigan. Nonetheless, hardiness zones are shifting, and there is plentiful experimentation underway by Wisconsinites to identify which tree species are appropriate for their location throughout the 21st century.

The Northern Institute of Applied Climate Science produced species vulnerability lists for six locations in Wisconsin, projecting what species are likely at increased risk (i.e. more vulnerable) under different climate change scenarios. Those are great resources that use the same background methodology as a species vulnerability analysis done for the Milwaukee metropolitan area.

The Go Outside Fund provides funding that helps connect youth to outdoor, nature-based learning experiences. Teachers or partner organizations may apply for funding to cover costs that facilitate getting kids outside and hands-on with nature, such as purchasing field supplies or paying for transportation and educator costs. Grants between $100 and $1,500 are available. Educators, as well as eligible organizations, are welcome to apply, with the next deadlines for applications being Sept. 1 and March 1, 2026.

When Can I Prune That Elm Tree?

Most urban foresters and arborists are aware of the historical significance of Dutch elm disease (DED). Introduced to the United States in the 1930s, this deadly fungus wreaked havoc on urban and rural forests throughout the United States. In many ways, DED was the impetus for many of the best practices of urban forestry we see today, such as species diversification and modern plant health care practices.

Likewise, most urban forest practitioners understand DED is still very much prevalent today, and if they are managing any lingering American elms, they know they can help decrease their susceptibility to the disease by not actively pruning or wounding them during the growing season. Pruning these elms during the growing season attracts bark beetles, which can carry thousands of DED fungal spores on their bodies. But elm is a complex genus; there are over 30 different species of elm and hundreds (if not thousands) of hybrids and cultivars in the landscape. So, which of these species and cultivars can you prune during the growing season, and which shall you not? Continue reading “When Can I Prune That Elm Tree?” →

By Mackenzie Manicki, DNR Natural Resources Research Scientist

The Wisconsin Department of Natural Resources has confirmed that the state’s first populations of the invasive vine pale swallow-wort (Vincetoxicum rossicum) have been found.

The populations were first detected in Oconto and Shawano counties, within the outskirts of Krakow along the shared county line.

These are the first known populations in the state, making rapid response efforts critical in preventing the establishment of this species in Wisconsin.
