Last year 195 Wisconsin communities achieved Tree City USA status, and those communities are home to nearly 60% of Wisconsinites. Wouldn’t it be something if we were number one in the country this year?! Well, here’s our chance – the application period for Arbor Day Foundation’s (ADF) recognition programs, including Tree City USA and Tree Campus USA, is now open!

How do Wisconsin professionals use outreach materials to engage residents in urban tree care?
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 activity in July
By Todd Lanigan, forest health specialist, Eau Claire, Todd.Lanigan@wisconsin.gov, 715-210-0150
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.
