Reminder:  2026 DNR Urban Forestry Grant Applications Due Oct. 1, 2025

Cities, villages, towns, counties, tribes and 501(c)(3) nonprofit organizations in or conducting their project in Wisconsin are encouraged to apply for a regular or startup 2026 Wisconsin Department of Natural Resources (DNR) Urban Forestry Grant.

The grants range from $1,000 to $25,000, and grant recipients must match each grant dollar for dollar. A startup grant of up to $5,000 is available for communities that want to start or restart a community forestry program. Grants are awarded to projects that align with state and national goals for increasing the urban forest canopy and the benefits it provides. These grants do not subsidize routine forestry activities. In total, $559,680 is currently available in regular and startup grant funding for 2026.

Issues including Tubakia leaf spot, mite damage and leaf scorch are all causing problems in northern Wisconsin and may be mistaken for oak wilt.

Witches’ broom is a term that describes a disease of many different plants. It’s a distinctive, abnormal growth typically caused by a pathogen — though in some cases it can result from insect feeding.

The namesake symptom appears as abnormally dense clusters of stunted shoots, branches, and foliage that strongly resemble a witch’s broom from storybooks and folklore. In Wisconsin, this is not often a critical forest health concern that merits management action, but Wisconsin Department of Natural Resources Forest Health staff recently observed widespread incidence of two particular witches’ broom diseases.

Tree managers met at Riveredge Nature Center (RNC) for a networking meeting/field tour at the end of July. RNC is located in Saukville, ground zero for Emerald Ash Borer (EAB) in Wisconsin, which was discovered in 2008.

The indoor portion of the meeting consisted of updates from DNR Urban Forestry and Forest Health staff.  There was also time for open sharing amongst attendees and an overview by Matt Smith (RNC) about what we’d be seeing in the field. Continue reading “Networking At Riveredge Nature Center” →

Golden oyster mushrooms (Pleurotus citrinopileatus) have eye-catching bright-yellow caps with branch-like white gills. Recently, more people have been noticing these gorgeous-looking clusters of mushrooms growing on trees in Wisconsin, especially in southern Wisconsin.

These mushrooms, prized for culinary delicacy, are native to eastern Asia. However, they are found in forests throughout the Midwest and northeastern United States, including Wisconsin.

Forest owners and land managers should look for beech leaf disease (BLD), a destructive beech tree disease in the United States, this summer.

Although it has not yet been found in Wisconsin, recent discoveries of the disease in Michigan and other nearby states highlight the continued importance of monitoring BLD’s expansion. There is potential for BLD to move into Wisconsin, as the eastern portion of the state overlaps with the native range of American beech.

There are plenty of trees in Wisconsin forests that haven’t been around as long as the Wisconsin Woodland Owners Association (WWOA).

In many cases, the 46-year-old WWOA has facilitated the information sharing, networking and hard work necessary to keep as many of those trees as possible, along with the older ones, of course, green and growing.

WWOA’s mission statement is one of those simple ideas that needs a lot of effort to become reality: “(T)o conserve and enhance the private woodlands of the state through the following actions:

  • Sustainably manage our woodlands with informed management plans that utilize best silviculture practices.
  • Assist private landowners in achieving their management goals by connecting them with natural resource professionals and fellow woodland owners.
  • Educate the public on the value of woodlands for economic, environmental, recreational and wildlife habitat purposes.”
