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.

S-shaped galleries under the bark of this ash were created by EAB larvae. You can also see epicormic branches (water sprouts) coming out of the trunk. These are a sign of significant stress in the tree. Photo Credit: Wisconsin DNR

WINTER FIRE SAFETY: Outdoor Brush Burning

Winter may seem like a perfectly safe time to burn, but it’s important to practice fire safety year-round to prevent wildfires. When the ground is entirely snow-covered, burning is permitted in DNR Protection Areas without a DNR burning permit for debris piles. As soon as the snow melts, DNR burning permits are required again. Always check with local fire officials before conducting any burning, especially in the spring.

Snow amounts vary across the landscape this time of year. The southern half of the state tends to have little to no snow, while the north looks like a winter wonderland. Just when you think winter is coming to an end, there’s that one lingering snowstorm to make everything white again. Suddenly, spring is finally here to stay, and it’s fire season!

Here are some tips for safe winter burning when the ground is snow-covered:

Winter Burning• Gather and pile brush in an open area away from over-hanging branches.
• If snow is in the forecast, place a tarp over the brush pile to keep it dry and time the burn, so the snow around the pile keeps the fire contained.
• When ready to burn, choose a calm day (less than 8 mph) with complete snow-cover on the ground.
• Snow must be next to the fire and stay there for the duration of the burn.
• Notify the local fire department and dispatch offices to avoid unnecessary fire response.
• Place small amounts of crumpled clean paper into the brush around the base of the pile.
• Light the paper all around the base of the pile. Do not use the fire to dispose of household garbage, rubber tires, oil or other accelerants.
• Using a rake or shovel, turn the debris into the flames to ensure all the materials are consumed.
• Avoid standing in direct contact or downwind of smoke and never leave the fire unattended.

Remember, spring is the peak of Wisconsin’s fire season. So, plan ahead and don’t wait until then to conduct debris burning. Better yet, consider alternatives to burning; compost, chip, leave brush for wildlife habitat or haul away to a transfer site.

2022 Tree City USA Requirements: Arbor Day Celebration And Proclamation

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

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

By Bill McNee, DNR Forest Health Specialist, Oshkosh, bill.mcnee@wisconsin.gov or 920-360-0942

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.

Learn About Wisconsin’s Urban Forestry Council In New 2021 Biennial Report

By Shahla Werner, Urban Forestry Council Chair and Plant Protection Section Chief for the Wisconsin Department of Agriculture, Trade, and Consumer Protection (DATCP)

The purpose of the Wisconsin Urban Forestry Council is to advise the state forester, currently Heather Berklund, and the Wisconsin Department of Natural Resources (DNR) on the best ways to preserve, protect, expand and improve Wisconsin’s urban and community forest resources.

The 27 members, who serve after being approved by DNR Secretary Cole, hail from all over Wisconsin. They represent a wide array of stakeholders, including citizens; municipal and utility foresters; medical and higher education professionals; nursery staff; environmental groups; public works, planning and parks staff; landscape architects; the Wisconsin Arborist Association (WAA); the Urban Wood Network Wisconsin; the League of Wisconsin Municipalities; and partner agencies like the Wisconsin Department of Transportation and the Wisconsin Department of Agriculture, Trade and Consumer Protection.

Understanding The Extent Of Invasive Species And Other Urban Forest Challenges

By Dan Buckler, DNR Urban Forest Assessment Specialist, Madison, daniel.buckler@wisconsin.gov or 608-445-4578

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.

Garden Planning – Avoid Invasive Plants

By Jaqi Christopher, DNR Forest Invasive Plant Specialist, Rhinelander, Jacquelyn.Christopher@wisconsin.gov and Mary Bartkowiak, DNR Forest Invasive Plant Coordinator, Rhinelander, Mary.Bartkowiak@wisconsin.gov

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.
