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.

Four Wisconsinites Receive ISA Award For Arborist Apprenticeship Program

Posted on by patricialindquist

The International Society of Arboriculture (ISA) recently awarded the Millard F. Blair Award for Exceptional Contributions to Practical Arboriculture to August Hoppe, Randy Krouse, Ben Reince and Jon Welch. Their contributions have been critical to the success of the Wisconsin Arborist Apprenticeship Program, the first arborist apprenticeship program in the United States.

Welch, Krouse, Hoppe and Reince also received the Urban Forestry Council’s Innovations in Urban Forestry Award

This program created a training model for turning new employees into skilled workers. The group has worked with the Tree Care Industry Association and the U.S. Department of Labor to get the arborist apprenticeship program approved. All four individuals actively serve on the Wisconsin Apprenticeship Advisory Committee and perform outreach.

How to look for white pine bast scale and Caliciopsis canker

The association between a tiny insect and an inconspicuous fungus is causing branch and sapling mortality. White pine bast scale (WPBS; Matsucoccus macrocicatrices) and Caliciopsis canker (caused by Caliciopsis spp.) are agents in an insect/disease complex impacting white pines (Figure 1).

Phomopsis galls

Posted on by eleanorvoigt

By Elly Voigt, DNR Forest Health Lab Technician and Communications Specialist, Eleanor.Voigt@wisconsin.gov

Galls are woody swellings on the branches or trunk of a tree and can be caused by insects or fungi. Winter and early spring are the best times to notice galls thanks to bare branches. One type of gall, caused by Phomopsis fungi, occurs on northern red oak, hickory, maple and several other tree species.

Numerous woody galls on the branches of an oak tree.

There will frequently be many phomopsis galls on one tree while nearby trees are completely unaffected, probably due to individual resistance differences. While small phomopsis galls have minimal effects on trees, larger galls can girdle branches, causing branch dieback. Galls grow very slowly, and many heavily affected trees survive for decades, even with a large gall on their trunk.

There are currently no treatment recommendations for Phomopsis galls, but you can prune and dispose of affected branches. Many landowners choose to let them be.

Recipients Announced for Urban Forestry Regular and Startup Grants

Posted on by patricialindquist

The Wisconsin Department of Natural Resources Urban Forestry program has selected the 2021 grant year recipients, funding 48 applications in a dollar-for-dollar match.

In addition to annual state funding totaling $524,600, the program received an additional $175,000 in federal funding to mitigate damage associated with the Emerald Ash Borer.

Awards for the 48 applications range from $2,400 to $25,000. In total, the projects cost an estimated $1.8 million. Six additional applicants may also receive second-round funding in spring 2021 if funds reserved for the Catastrophic Storm Grant program are not needed through the winter months.

Of the selected applications, 28 are regular grants, and 20 are startup grants. The six chosen for possible second-round funding are all regular grants.

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
