When cleaning up your garden this fall, be sure to dispose of yard waste properly. Not only is dumping on public lands illegal, but it is harmful to the environment.

With the dropping temperatures and changing leaves, it’s beginning to feel like fall hunting season.
While you travel across the state to check hunting spots or tend to food plots, look for unwanted hitchhikers on your clothing and equipment. Seeds from invasive plants like garlic mustard, tansy and spotted knapweed can travel far distances in the mud on your vehicle, trailer, ATV, shoes and clothing.

Twolined chestnut borer (TLCB) attacks on oak trees have increased in numerous Wisconsin counties, with decline and associated mortality in the last two growing seasons, most noticeably since August.
Symptoms of infestation by this native beetle are initially seen in mid-July on the outer portions of branches in the upper crown. Leaves begin to fade from green to yellow to red. Within a matter of weeks, they turn brown and remain on the branches for weeks to months. Their foliage may also appear sparse or completely bare (Fig. 1).

Don’t Move Firewood, The Nature Conservancy
October is Firewood Month! Help prevent the spread of invasive insects and diseases by buying firewood where you burn it.
Firewood Scout can help you find local firewood for sale.
See the DNR website for more information on invasive species and forest health. Continue reading “Moving Firewood Can Spread Invasive Species”

Governor Tony Evers proclaimed the third week in October as Forest Products Week in Wisconsin to recognize forests’ essential role in the state’s environment and economy. This week celebrates Wisconsinites who work in the forest products industry while considering the many ways forest products can improve our lives. Forest Products Week also highlights Wisconsinites working in and caring for our state’s forest land. Continue reading “Wisconsin Forests – Rooted In Our Lives, Rooted In Our Economy”
The Wisconsin DNR Urban Forestry’s own Laura Buntrock, Urban Forestry Program Specialist, and Olivia Witthun, Urban Forestry Coordinator, were awarded the National Association of State Foresters’ (NASF) Steve Sinclair Current Achievement Award for Urban and Community Forestry for their work in the recently published study on the economic benefits of urban and community forestry (UCF). The award ceremony took place at NASF’s 2022 annual meeting, and their awards represent extraordinary contributions to state and private forestry.

The economic study, covering the entirety of the Northeast-Midwest region (20 states and the District of Columbia), is the first comprehensive analysis of economic UCF benefits at a regional scale. Its findings justify the enhancement of current UCF programs and the creation of new initiatives to support urban forest management. They have already helped launch similar research in the South and the state of California.

The scientific community continues to grow its understanding and appreciation of the ecosystem services that urban trees offer. That is, we now know more about the good trees do, but we also better understand what we don’t know. This nuanced perspective has manifested itself in updated estimates of ecosystem benefits within the Wisconsin Community Tree Map (WCTM).
The WCTM is a compilation of tree inventories from around the state, comprising 910,000 trees across 180 organizations. One of the application’s many interesting and useful functions is the estimation of trees’ eco-benefits. This information can be found for an individual tree simply by clicking it and then the “Eco-Benefits” box. The eco-benefits can also be estimated for a collection of trees by navigating to the “Hub” tab, then clicking “Stats” and “Ecosystem Benefits.”
Estimated benefits showcased in the tree map include annual stormwater reduction, air pollutant reduction and carbon sequestration, as well as lifetime carbon storage. All these benefits are expressed by quantity, volume or weight and by the monetary impact of the trees.

Generally, attention to the planet’s extinction crisis focuses on charismatic animal species. But what about a different branch of life, one that appeals to those with specific interests and expertise (such as readers of this article)? What is the status of America’s trees?
An extensive study published in the journal Plants People Planet documented all tree species native to the contiguous United States and classified their global extinction risk, creating or updating hundreds of species threat assessments. The results provide one of the most comprehensive appraisals of trees across the country, informing not just our expectation of these trees’ future ecological and economic roles but our moral duty as stewards on and for this planet.

After being postponed twice due to the pandemic, the third time was a charm. The Wisconsin Department of Natural Resources (DNR)’s Urban Forestry Team hosted the first of three Community Tree Management Institute (CTMI) V sessions. The CTMI session took place at the Green Lake Conference Center in Green Lake, Wis. and brought together DNR Urban Forestry staff and 28 students from across the state. CTMI students, community foresters, utility foresters, UW Extension staff and a tree board member served as instructors to help educate and led exercises for the 2-day event.
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 – think of your typical small Wisconsin community’s Public Works Director. This CTMI class jumped right in from the get-go and were very involved in the conversations. The foundations of urban forestry were covered in this first session. The second session, February 2023, will cover planning, operations and biology. The third session, June 2023, will bring it all together. An applied project is also a requirement of attendees; each will work on something that will benefit their community’s urban forest. Continue reading “CTMI V Session I Successfully Completed”
The Arbor Day Foundation’s Recertification application portal for this year is now open and available. The Arbor Day Foundation’s Tree City USA program is working to help grow the urban tree canopy in Wisconsin. With more than 200 designated communities, almost 60% of Wisconsinites live in a Tree City USA community.
Tree City USA communities show a strong commitment to growing and maintaining a healthy tree canopy. To receive the recognition, communities must:
