If we use the K.I.S.S. principle, then here is your formula: if your tree needs water, then water it. If your tree doesn’t need water, then don’t. Continue reading “Tree watering: a simple act, a science and an art, but bottom line – all trees need water (even in autumn)”
The Wisconsin Department of Natural Resources (DNR) and UW-Madison Division of Extension (UWEX) are partnering to better understand the informational resources available to professionals who provide tree care advice and services to urban residents in Wisconsin. Using information collected from an exploratory survey in early 2019, DNR and UWEX staff plan to improve access to these resources and address additional needs by creating new resources. Next steps include identifying a place where existing and new materials can be easily accessed by all audiences.
When asked to report the most commonly discussed topics with homeowners, pests and diseases emerged as the top issue (36% of respondents) with tree planting/care/selection or tree pruning as other popular topics (20-23% of respondents respectively). While 75% of respondents say that they use verbal advice to share information with residents always or most of the time, they also identified a diverse range of topics and types of content that they would find useful when communicating with their audiences.

Fall webworm started showing up in early July. This native insect feeds on deciduous trees and shrubs and appears every year in yards and forests. Fall webworm forms loose webbing over branch tips. It can even completely cover a small tree with webbing. Inside the webbing you will find both live and dead caterpillars, partially eaten leaves and frass (caterpillar poop).
Fall webworm is more of a cosmetic issue than a tree health problem, but if people are concerned, they can take some simple measures to remove them. Open up the webbing using a rake, fishing pole, long stick or another long tool.. This will allow predators to get at the caterpillars inside. Or people can use their tool to roll up the webbing, peel away from the branch and place the entire web in a container of soapy water for a couple of days.
Insecticides can also be used to control this insect. If you decide to go this route, make sure the insecticide is labeled for caterpillars/fall webworm and that it will penetrate inside the webbing. With all pesticides, the user needs to carefully read and follow label directions.
As a native insect, fall webworm defoliation is unlikely to cause any harm to healthy trees. Use a control method described above if you are concerned about the aesthetics of a defoliated tree. Do not prune off the branch or burn the nest. Burning will cause more harm to the tree than the caterpillars will. For more information about fall webworm, visit this page from Michigan State University Extension.
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 2020 Department of Natural Resources 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.
Communities and organizations interested in applying for a 2020 Urban Forestry Grant may find the grant application informational video to be a valuable resource. It highlights priorities of the Urban Forestry program and discusses several other key aspects of the application process. The video is approximately eleven minutes long and includes topics such as the difference between startup grants and regular grants and how to contact an Urban Forestry Coordinator.
The application period opened July 1, 2019 and closes October 1, 2019. To view the application and informational video, visit the Urban Forestry Grant’s website. If you have questions regarding application process and eligible projects contact your DNR Urban Forestry Coordinator.
Once again, the Village of Gays Mills will be providing excellent community forestry training for surrounding partners and cooperators. Workshop attendees will learn basic information to manage and care for their trees throughout their lifespan. Use the brochure found here to register. For any questions, please contact Cindy Kohles, Gays Mills Village Forester, at (608) 872-2184.
Green Bay Packers and DNR staff plant a ceremonial Sterling Linden tree in Titletown to help offset the Green Bay Packer’s carbon footprint produced by traveling to away games. Trees naturally sequester carbon dioxide, providing a long-term solution to the problem because trees sequester more and more carbon as they grow larger. This marks the 9th year of the Packer’s First Downs for Trees (FDFT) Program which has planted 5,144 trees to date throughout Brown County.
How does a community manage to increase its street and park tree species diversity by 445% without spending ANY public funds to purchase trees?!! Look no further than the Village of Cambridge, WI (pop. 1,500) for an answer. Continue reading “Cambridge Tree Project”
Providing timely and relevant information to the Wisconsin urban forestry community is a key role of the Wisconsin DNR Urban Forestry program. One of the ways in which this goal manifests itself is through a monthly newsletter received by 5,555 subscribers (May 2019). In order to ensure that the newsletter content is relevant and timely, the Urban Forestry program surveyed subscribers in spring 2019. Results are shown and interpreted below and suggestions made for future newsletter editions. Continue reading “Wisconsin DNR Urban Forestry News subscriber survey”

Invasive plants have been shown to impact Wisconsin’s economy, environment and human health. Roadsides are a key area where these unwanted plants establish and spread. These right of way habitats are challenging to work in but focused efforts can be successful in preventing spread and reduce invasive plant populations.
To help educate and jumpstart management, The University of Wisconsin-Madison Extension along with 4-Control are conducting roadside invasive plant workshops throughout the state. We invite you to attend one of these five regional workshops. While this training is available to anyone interested, the focus will be on training staff of municipalities that manage vegetation on roadsides.
