The Wisconsin Department of Natural Resources’ (DNR) Forest Health team has debuted seven new fact sheets, providing information on various forest insects and diseases as well as tips on how to deal with their emergence on your property.
The new fact sheets provide details on spongy moth, oak wilt management, spruce budworm, jack pine budworm, tamarack insects (larch casebearer and eastern larch beetle), red pine pocket decline and mortality and a comparison of common spring defoliator caterpillars (forest tent caterpillar, eastern tent caterpillar and spongy moth).
Additionally, the Forest Health team has updated and/or refreshed the look of its 13 existing fact sheets.

The Wisconsin Department of Natural Resources (DNR) just released a new publication: Results of the 2020 Diverse Urban Species Survey.
You may have participated in this survey led by DNR Urban Forestry Coordinator Don Kissinger in 2020 (if so, thank you!) Wisconsin municipalities with more than 2,500 residents were asked a series of questions about the types of trees they prefer to plant (such as root stock type and caliper size), which lesser-used species they had successfully planted, which species they cannot find but would like to plant, and whether they use a gravel bed.

The forest health team has produced four new factsheets since the start of 2020. These resources are designed to be informative, 2-page documents for a wide audience that includes landowners, foresters and natural resource professionals, educators, and more. The new factsheets of 2020 are linked below, and more will be announced as they are finalized:
Please check them out and our other recently updated factsheets about Heterobasidion root disease, oak wilt, conifer bark beetles, and hickory decline and mortality. You can find all of these and more forest health publications in the publications catalogue and on the DNR forest health webpage.
The DNR Forest Health team recently updated its factsheet on common forms of abiotic (non-living, chemical and environmental) damage to trees in Wisconsin.
The factsheet provides a brief overview of the following topics:
- Storm damage (wind, lightning, hail)
- Winter damage (ice and heavy snow, frost, sunscald, salt spray, winter desiccation)
- Soil (compaction, improper pH and nutrient deficiencies)
- Pesticides (improper use, drift)
Find this factsheet, as well as the complete collection of DNR Forest Health publications, on this webpage.
Every wonder if you can successfully plant trees in the fall? Which species are suited to a fall planting and which aren’t? Check out this article from Iowa State University Extension and Outreach. Even though it originates from out of state, much of the information is applicable to the Midwest, including Wisconsin.
The professionally-designed version of the Heterobasidion root disease (HRD) stump treatment guidelines is now posted on the DNR’s HRD webpage. The revised stump treatment guidelines, developed to reduce the risk of introduction and spread of HRD in Wisconsin, were implemented January 1, 2019. The content is the same as the guidelines that were approved last year, but this document has a layout that is much more user-friendly. Explore the new look of the HRD guidelines.
“What tree should I plant?” This is one of the most common questions urban forestry professionals are asked. Well, the answer depends on many different factors. Continue reading “Figuring out what tree to plant this spring?”

The Wisconsin DNR is seeking public comments on a proposed revision to silviculture guidelines for emerald ash borer (EAB). Stand-level EAB silviculture guidelines were originally released in 2007, with periodic reviews and updates. A DNR technical team and stakeholder advisory committee prepared the current version using multiple sources of information, including recent research findings, identification and locations of new EAB infestations, economic considerations, and experience gained from implementing previous versions of the guidelines.
The draft document and information about the public comment process can be found at https://dnr.wi.gov/news/input/Guidance.html#open through Tuesday, October 9, 2018. All comments must be submitted by that date.
