Forest managers planning silvicultural treatments in stands susceptible to spongy moth (Lymantria dispar) – such as those containing many host species, including oak, birch, aspen and basswood – are encouraged to conduct annual egg mass surveys before treatment.

Surveys make it possible to predict if heavy defoliation is likely. If more than 30 egg masses are found in a sample area – a circle with a 37-foot diameter – then heavy defoliation is expected in the spring, and management activities should be altered or delayed until an outbreak has ended.

Numerous research studies support the idea that green spaces and vibrant tree canopy at school campuses are important for students’ academic and socioemotional growth. But that can be easily overlooked during construction, design build and as our school grounds in our communities age over time. Municipal foresters and tree boards can be part of driving positive change.

Three critical preconditions for learning – ability to concentrate, intrinsic motivation and manageable levels of stress – have been linked to green schoolyards in recent research[1]. At the LEAF K-12 Forestry Education Program, a partnership between the DNR Division of Forestry and University of Wisconsin – Stevens Point, our resources can help you get students outdoors and connected with nature. For example, our Forest Mapping activity provides learners with hands-on outdoor mapping investigations of their school campus.

Please Submit Trees Planted This Year

Wisconsin Tree Planting MapAutumn is a great time to plant trees. 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.

While the DNR may be able to track the ultimate destination of seedlings grown at the state nursery, or trees which have been funded by DNR grants, there are so many others planted across Wisconsin which go undocumented. The planting map was designed to help fill that void and to ensure that those trees are accounted for in our tallies.

Whether it was a planting of one tree or a thousand, take a couple minutes to submit your information through an easy-to-use survey.

Tree City USA Application Portal Now Open

Posted on by patricialindquist

The application portal for Tree City USA is now open and available. Applications are due Dec. 31.

You will notice some changes to the recognition portal this year. These instructions will help you log in for the first time.

We hope you join us again this year in continuing our strong commitment to growing and maintaining a healthy tree canopy across Wisconsin. If you’re new to Tree City USA, you can learn more about the program on the Arbor Day Foundation’s website and from your DNR Urban Forestry Coordinator.

If you’ve been a Tree City USA for at least one year, you may want to see whether you’re eligible for a Growth Award. The Growth Award is presented by the Arbor Day Foundation to participating Tree City USA communities that demonstrate higher levels of tree care and community engagement during the calendar year. Communities need to earn at least ten points in any of the following five categories: Building the Team, Measuring Trees & Forests, Planning the Work, Performing the Work and The Community Framework. Review the point system to see if you’re eligible this year and talk to your Urban Forestry Coordinator if you have any questions.

From Decaying Park To A Vision For Tomorrow: The Story Of Mauston’s Living Food Pantry

Posted on by patricialindquist

By Randy Reeg, former City Administrator, Mauston

The city of Mauston (Juneau County, Wisconsin) is a small rural city of just under 4,500 people, situated along the I-90/94 corridor in central Wisconsin. Despite having a highly successful local manufacturing economy, a regional medical center and being situated in heavily trafficked regional tourist destination area, Mauston and Juneau County both have lower than average incomes and high levels of poverty. The region is one of Wisconsin’s rural food deserts, and the local food pantry, the Community Sharing Pantry, plays a crucial role in fighting local hunger.

The city of Mauston has seven public parks, and like in most other communities, the amenities, popularity and usage of each park differs greatly. Marachowsky’s Park is an approximately 2-acre mini park located on the city’s west side. It had historically contained a youth baseball field, a picnic shelter, playground equipment and public restrooms. Following the summer of 2019, Mauston’s Summer Recreation Director at the time advocated for the relocation of the youth baseball field to a different park for logistical purposes, including the muddy and mosquito-ridden conditions. The Parks & Recreation Board and City Council both agreed, and by summer of 2020, youth baseball was no longer an activity at Marachowsky’s Park.

Time To Seek Out Spongy Moth Egg Masses

The Wisconsin Department of Natural Resources (DNR) is encouraging property owners to seek out and dispose of spongy moth egg masses, which were produced by adult moths during the summer.

Each spongy moth egg mass contains hundreds of eggs that will hatch into hungry, leaf-eating caterpillars in the coming spring. Large numbers of these invasive caterpillars can be a tremendous nuisance that may cause tree mortality.

Aphids — and the honeydew they produce — have made their mark on trees in Wisconsin during 2023.

Midway through the summer, oak trees in areas of Vilas and Oneida counties were buzzing with activity. During September, beech trees in eastern Wisconsin became busy with a different species of aphid.

A look at the two situations:

Young Tree Training Pruning Workshops

Posted on by patricialindquist

The Wisconsin Department of Natural Resources (DNR) and UW-Madison Extension have teamed up to offer young tree training pruning workshops at five locations around the state. Wachtel Tree Science will be presenting the information in a morning-indoors-afternoon-outside format. The cost is $35 including lunch, and ISA Continuing Education Units (CEUs) will be offered. 

Set your trees up to thrive and help alleviate storm damage by properly pruning your trees when they’re young. It’s an excellent investment of resources providing exponential savings in the future.

Please register ASAP as these start in just a couple weeks.

Now that spongy moth egg laying is complete for 2023, it’s a good time to look for and dispose of the egg masses produced by adult moths over the past two months.

Spongy moth egg masses are tan-colored lumps about the size of a nickel or quarter, and can be found on trees, buildings and other outdoor objects. They may also be found in protected places such as firewood piles and birdhouses.

Wisconsin Urban Forestry Council Welcomes New Members; Says Goodbye To Others

Posted on by patricialindquist

The DNR’s Division of Forestry recently welcomed three new members to the Wisconsin Urban Forestry Council and said farewell to several members who contributed much to the council.

The Wisconsin Urban Forestry Council is an advisory committee to the DNR’s Division of Forestry, guiding the best ways to preserve, protect, expand and improve Wisconsin’s urban and community forest resources. The council is comprised of 23 people appointed by the Secretary of the DNR. Members represent the diverse groups and interests that impact our state’s urban and community forests, including representatives from professional organizations, private business owners, educators, green industry employees, nonprofit/service organizations, governmental agencies, municipalities of various sizes, utilities, concerned and active citizens and trade organizations throughout the state.
