Property owners with healthy, valuable ash trees are encouraged to treat them with insecticide this spring to protect against emerald ash borer (EAB). The pest is currently the most damaging threat to trees in Wisconsin, killing more than 99% of the ash trees it infests.

Ash tree branch in West Allis has been damaged by woodpeckers. Sections of bark are missing or have been flecked away.

Emerald ash borer (EAB) continues to spread into areas of Northern Wisconsin and was detected for the first time in Lincoln County, in the Town of Harrison and the City of Tomahawk. EAB was first identified in Wisconsin in 2008, only 14 years ago. It is now in 62 of Wisconsin’s 72 counties.

2022 Tree City USA Requirements: Arbor Day Celebration And Proclamation

Posted on by patricialindquist

An Arbor Day celebration and proclamation will be required in 2022 to earn or maintain Tree City USA designation. An Arbor Day celebration will also be required to earn or maintain Tree Campus Higher Education and Tree Line USA recognition.

There are many ways a community/campus/utility might meet this standard, including:

  • An in-person gathering (e.g. community tree planting or festival)
  • A virtual event (e.g. webinar or live streamed tree planting)
  • A social media post or campaign

DNR Announces Additional Funding Now Available For Communities Impacted By Storm Damage

Posted on by patricialindquist

The Wisconsin Department of Natural Resources (DNR) announced that five communities impacted by severe weather last July will receive an additional $123,600 of aid from reserve funds.

On July 28, 2021, Marathon County and the cities of Omro, Ripon, Tomahawk and Watertown each experienced catastrophic storm damage following severe weather conditions.

Initially, the five grant applicants sought $228,435 from the DNR’s Urban Forestry Catastrophic Storm Grant program to lessen the burden of the impacted communities. However, the grant funds were limited to $104,920.

To assist with funding, the DNR submitted a request in November to the Joint Committee on Finance to transfer additional funds from the forestry emergency reserve.

90 New Municipal Detections Of Emerald Ash Borer In 2021

Posted on by patricialindquist

In 2021, emerald ash borer was found in 90 more communities in Wisconsin than in 2020, including 10 cities, 14 villages and 66 towns. This increased the total number of communities with a reported emerald ash borer detection 11% to 898 at the end of 2021.

Emerald ash borer was confirmed for the first time in Barron, Iron and Langlade counties during the year. It has now been found in 61 of Wisconsin’s 72 counties and confirmed on Oneida Nation land, and we believe additional unreported infestations are present.

Municipal emerald ash borer detections during 2021 are shown in orange. Older detections are shown in green or blue. Map courtesy of Wisconsin Department Agriculture, Trade and Consumer Protection.

How extensive are buckthorn and other invasive species in our communities? We don’t know yet, but Wisconsin’s Urban Forest Inventory And Analysis (UFIA) project will be able to answer that and many other questions.

Besides simple stem counts, we can learn about the type of land where buckthorn is found, species under which buckthorn is growing and trends in invasive species expansion or decline over time.

With winter in full swing, many gardeners dream of spring and begin planning what plants to add to their gardens. Now is a great time to brush up on what not to plant to avoid invasive species that might be hiding in plain sight.

Woodlot in fall, most trees have lost their leaves which are covering the ground. Several burning bush shrubs still with their bright red leaves stick out against the brown backdrop.
