Forest Health Factsheet: Environmental Causes of Tree Damage

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)
  • Drought
  • Flooding
  • Fire
  • 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.

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.

Forest products celebrated

Forestry organizations, businesses, and communities celebrated Wisconsin’s diverse forest products sector during National Forest Products Week on October 15-21, 2017. Gov. Scott Walker also proclaimed the week as Forest Products Week in Wisconsin, encouraging citizens to recognize the many products that come from our forests because of the people and businesses that work in and care for forests.  Several forest products businesses and organizations hosted open house events throughout the week.  DNR produced a new handout to showcase the economic value of Wisconsin forests.  If you’d like copies of this printed publication, send an email to DNRFRPublications@wisconsin.gov noting your street address, the number of copies you’d like and the publication code number (FR-698).
