Learn More About Rime Ice And Winter Tree Damage

During Wisconsin’s first week of 2021, a beautiful weather phenomenon occurred: rime ice. Rime ice forms when the tiny water droplets in fog freeze on trees and other objects. Hoarfrost, a similar phenomenon that occurs without fog, can form when water vapor in freezing air contacts a surface. The best news is that these winter conditions should not concern tree health when we emerge from the winter fog in spring.

Emerald ash borer (EAB) reports continued to grow across Wisconsin in 2020. The total number of communities with EAB was 808 as of December, an increase of over 50% since the start of 2020. In addition, the insect was confirmed for the first time in six additional counties (Dunn, Florence, Oconto, Pepin, Price and Shawano) during 2020. EAB has now been found in 58 of Wisconsin’s 72 counties and confirmed on Oneida Nation land. Additional unreported infestations are widely believed to be present.

Staff Highlights of 2020

Posted on by patricialindquist

As the year draws to a close, we asked DNR urban forestry staff to reflect on the last twelve months and choose their top highlight – whether it’s a project they’re especially proud of, a new partnership or a deeper relationship with coworkers. Here are their responses:

“The highlight of my year has been watching the partners we support achieve lasting impacts via their Urban Forestry projects. Two immediately come to mind. Restoration Of Our Trees Sheboygan (ROOTS) kicked off their EAB Mitigation Grant Program by funding five separate projects in Sheboygan County communities for a total project value of $165,500. The other is Cedarburg Green who instituted a public awareness campaign to encourage community leaders to refund the city’s tree planting budget. Their campaign consisted of a common council presentation, an educational workshop and tree sale for residents, Arbor Day plantings, student art and writing contests, tree benefit tags, multiple news articles and a “Trees of Distinction” booklet, video and walking tour.”  -Olivia Witthun, East Central Regional Urban Forestry Coordinator
